Microprocessor based robotics arm

Microprocessor based robotics arm Abstract Robotic arm has become popular in the world of robotics. The essential part of the robotic arm is a programmable microprocessor. The microprocessor based brick capable of driving basically three stepper motors design to form an anthropomorphic structure. The first design was for experimental use on a human-size industrial robot arm called PUMA 560 which stands for Programmable Universal Machine for Assembly. This human size robot was used to explore issues in versatile object handling and compliance control in grasp actions it was done in Bejczy city in the Jan, 1986. This paper explains the method of interfacing the robotic arm stepper motors with the programmed 8051-based microprocessor which are used to process and control the robot operations. We have employed the assembly language in programming our microcontroller of the microprocessor. A sample robot which can grab by magnetizing and release small objects by demagnetizing is built for demonstrating the method explained. 1. Introduction A robotic arm is a robot manipulator which is programmable and its functions are almost similar to that of human arm. The links of such a manipulator are connected by joints allowing either rotational motion or translational displacement. Kinematic chain can be formed by the links of the manipulator. The business end of the kinematic chain of the manipulator is called the end effecter and it is analogous to the human hand. The end effecter can be designed to perform any desired task such as welding, gripping, spinning etc., depending on the application. The robot arms can be autonomous or controlled manually and can be used to perform a variety of tasks with great accuracy. The robotic arm can be fixed or mobile (i.e. wheeled) in the nature and can be designed for industrial or home applications. 2. Robotic Arm The word robotics, the meaning and the study of robots was done by a famous foreign scientist Isaac Asimov. Robotics is a branch which involves elements of mechanical and electrical engineering in it, as well as control theory, computing and now artificial intelligence in it by which we can implement it in the different fields. According to the Robot Institute of America, â€Å"A robot is a reprogrammable, multifunctional manipulator designed to move materials, parts, tools or specialized devices through variable programmed motions for the performance of a variety of tasks†. The way in which we are going to use robotic term in the form of arm is called as robotics arm. In order to perform any useful task the robot must interface with the environment, which may comprise feeding devices, other robots, and most importantly people. As the robot with which we are going to deal with work as arm and is therefore known as robotic arm 3. Types Of Robotic Arm There are various kinds of the robotic arm available in the market for the different tasks these are as follows. i. Cartesian Robot / Gantry Robot. ii. Cylindrical Robot. iii. Spherical Robot / Polar Robot. iv. SCARA Robot. v. Articulated Robot. vi. Parallel Robot. 4. Block Diagram For Robotic Arm The method employed in designing and construction of the robotic arm is based upon the operational characteristics and features of the microcontrollers of the microprocessor, stepper motors, the electronic circuit diagram and most importantly the programming of the microcontroller of the microprocessor and mainly the stepper motors. This work is able to successfully accomplish the defined functionality means it defines all the functions of the robotic arm. A sample robot which can rotate, magnetize an object, lower and raise its arm, by being controlled by the 8051 microcontroller of a microprocessor is built successfully and it was named as robotic arm. The 8051-development board is soldered and it used the required procedure for the correct operation of the controller. The 8051 development board has been interfaced to the stepper motors such that the anthropomorphic like structure can be controlled from the buttons at the base of the structure which is robotic arm. These buttons help to control the whole system of the robotic arm. These four buttons have the uncommon task from each other which is explained as follows. On/Off The ON button puts on the system while the OFF button puts off the system. This is only the task allotted to them just to ON and to OFF the robotic arm. Start/Stop The START button starts the initial movement of the whole arm from its reset point, while the STOP button takes the arm back to its reset button after completion of its movement applied for the required task. Right-Left/Left-Right When this button is switched to the RIGHT-LEFT part it causes movement from right to left, while the LEFT-RIGHT part causes movement from left to right. It is used only for the right and left movement. Rotation Of 180/90 When the button is on 180, it causes a rotation of 180 degree of the base stepper motor, but when put on 90 degrees, it causes rotation of 90 degrees. It means it is used for the 90 and 180 degree rotations. 5. Mechanical Structure Of The Arm For the construction of any kind of the robot we must have any kind of the idea over which we have to work for its construction. Same is the case of the robotic arm for its construction we need its mechanical structure. In constructing our robotic arm, we made use of three stepper motors and gears since our structure is a three dimensional structure. A typical prototype that we employed for the construction of our robotic arm. There is a stepper motor at the base of the arm, which is used for circular movement of the whole structure for the easiness of the task; another stepper is at the shoulder which allows for upward and downward movement of the arm again used according to the task given to the robotic arm; while the last stepper motor is used at the wrist which allows for the picking of objects by the magnetic hand. 6. Robotic Arm Design Process It includes various points related to the designing of the microprocessor based robotics arm. All those points which explain them are as follows: Defining The Problem i. Identifying the purpose of a construction. ii. Identifying specific requirements. A community wants to construct a robotic arm. Design and build a prototype device which could satisfy this need. Design and build a prototype device which could satisfy this need. You need to determine what problem you are trying to solve before you attempt to design and build a robotic arm to solve a problem. Researching And Designing i. Gathering information. ii. Identifying specific details of the design which must be satisfied. iii. Identifying possible and alternative design solutions. iv. Planning and designing an appropriate structure which includes drawings. Creating A Prototype i. Testing the design. ii. Troubleshooting the design. Building Your Robot Construction work can now begin. Here are some sites that help with: i. Structure. ii. Gear combinations. iii. Arm mechanisms. iv. Placing sensors. v. Hints and tricks. vi. The Art of LEGO Design by Fred Martin an excellent resource for building very strong structures. Programming And Testing Your Robot Now it is time to program your robot. This can be achieved in many different ways. Use can achieve rudimentary intelligence in your robot by using only relays, potentiometers, bump switches and some discrete components. You can increase complexity in intelligence in your robot by adding more sensors and continuing in the same vein of using hardwired logic. By introducing a more sophisticated control element, the microprocessor, you introduce a significant new tool in solving the robot control problem. Evaluating Your Robot i. Evaluate the design. ii. Evaluate the planning process. As building and programming work progresses, and the design begins to take shape, you will automatically carry out tests on the design. You will also need to complete systems tests at various stages of the construction. If any of the tests show that you have failure in a joint, or that part of your structure is not meeting specifications, then you will have to make modifications in your plan. When building and programming is complete, the entire project must be tested to see if it does the job for which it was designed. An evaluation needs to then be written. This should be a statement outlining the strengths and weaknesses in your design. It should describe where you have succeeded and where you have failed to achieve the aims set out in the specifications. 7. Overall Arm Design The two arms used both have six degrees of freedom, and are mounted on the humanoid robot cog. The arms are mirror image of one another. The kinematics of the arm is designed to be similar as that of the human arm. There are two joints each at shoulder, elbow and wrist although the axis of the first elbow joint is coincident with the co-axes of the shoulder joints. The arms has length same as that of the length of the human arm. 8. Market Applications Of Robotics Arm Applications of robotic arm are very effective in the market world. There are various fields where there is a deemed need of the robotic arm these can be explained as follows. Automotive Robotic arm can be used in different ways in the automotive field. i. Power train Control ii. Body Electronics iii. Driver Information Systems iv. Chassis v. Safety vi. Automotive Networking Consumer Robotic arm can be used in different ways in the consumers. i. Mobile Consumer Electronics ii. Home Electronics Industrial Robotic arm can be used in different ways in the industrial field. i. Factory Automation ii. Building Control iii. Metering iv. Medical v. Point of Sale/Kiosks vi. Home Appliances Medical Robotic arm can be used in different ways in the medical field. i. Home Portable ii. Diagnostics and Therapy iii. Imaging iv. Intelligent Hospitals Networking Robotic arm can be used in different ways in the networking field. i. Network Security ii. Home and SOHO Networking iii. Network Storage 9. Future-Scope The scope of this work for manufacturing of robotics arm involves confirming the 8051 micro-controller of microprocessor. Input/output (I/O) signals are compatible with that of the robotic arm stepper motors and testing of the robots motor signals through programming the 8051 microcontroller of the microprocessor. Assembly programming is used to develop the programs for the EPROM 2732 on the 8051 micro-controller of the microprocessor platform that takes robots motor signal as I/O and controls the robot operation programmatically. We have assumed that after figuring out the interface issues for the Robot with the 8051 microcontroller, the same knowledge can be extended to make very complex robots with enhanced functionality. With the technique used in the manufacturing of the robotic arm we can also make other robots for the different tasks. Conclusion Finally from this topic we can conclude a robotic arm is an instrument by means of which we can do any kind of the task and use it in the way in which manner we want to solve the task. The controlling software used in this robotic arm can be general for any kind of robot arm and set of sensors. This paper introduces a set of design principles which seek to reduce robotic applications design and implementation time so reducing the errors present in any practical implementation as well. Experiments show that the solution presented in this paper, although its limitations, allow the robotic applications designer to save development time while keeping the overall complexity low. There exists open-source applications which handle similar problems but they are not well fitted for small control applications. We have learnt that because of limitations in the programming language used to develop the application and the final application itself is highly sensitive to implementation issues. Also , to completely verify the design principles it would be necessary to evaluate the effort required to design a control application for multiple and heterogeneous platforms.

Intersectionality and assignment Essay

Intersectionality Assignment The definition of intersectionality states that it is the social theory suggesting various socially and culturally constructed categories of discrimination interact on multiple and often simultaneous levels, contributing to systematic social inequality. Intersectionality holds that the classical models of oppression within society, such as those based on race/ethnicity, gender, religion, nationality, sexual orientation, class, or disability do not act independently of one another; instead, these forms of oppression interrelate creating a system of oppression that reflects the â€Å"intersection† of multiple forms of discrimination. (http://geekfeminism.wikia.com/wiki/Intersectionality) I think the author intended to include intersectionality in the story to show that people have the tendency to categorize others immediately without even getting to know them. As humans we judge others way too much for our own good and we don’t even realize we are doing it majority of the time. I think Morrison’s main purpose in Recitatif is to make the reader a lot more aware of their stereotypical judgements about different races based on the use of different signs that Twyla and Roberta display as characters throughout the story. By writing with this technique of using hidden signs in the text it makes the reader begin to try to naturally figure out the races of Twyla and Roberta. She also includes things in this story such as their views on intelligence, physical appearance, racial tensions, wealth and social class. I think Morrison hopes to make her readers aware that we are all guilty of using stereotypes that this society has created for us. It’s just what we have known all our lives. Maybe a learned behavior from our parents, grandparents, or anyone we are around a lot. Everyone, even if they are racist or the most non-racist human being on earth, makes judgments on a â€Å"different† person that doesn’t fit into their â€Å"norm †. If I had to take a guess I would say Twyla is black and Roberta is white. One part in the story Roberta says that â€Å"they never washed their hair and they smelled funny†,  referring to Twyla. Roberta also said this about Twyla’s mother â€Å"She was big. Bigger than any man and on her chest was the biggest cross I’d ever seen. I swear it was six inches long each way. And in the crook of her arm was the biggest bible ever made.† This description sounds like a big African American mother because that’s what you could picture her as. Being Christian, not interested in being friends with Roberta’s mother, and storming away from her gets my mind visualizing that she is the attitude black big momma type of woman. Another thing I decided to look at to help me decide was their names. As the story goes on it gets harder to keep the same the same thought process on who’s apart of what race because of the different stereotypes and statements that are made by the characters when they continue to cross paths later in life. Also because as an individual you start to realize that you are judging and trying not to. For me that begun a whole new way of thinking and continuously changed my opinion about the reading several times At times Roberta could possibly be the black girl and Twyla could be white. In conclusion, its basically left up to you to decide who’s what race and its really going to open your eyes to how judgmental you can be and how big of a role these everyday stereotypes really have on your mind, even when it seems that you have no racism or judging in you.

Essay about North by Northwest, by Alfred Hitchcock

Alfred Hitchcock’s film North by Northwest (1959) is famed as a classic man-on-the-run thriller, following protagonist Roger Thornhill as he flees across state lines in a mad dash to save his life and unravel the mystery to his extraordinary predicament. However, mid-way through the film Thornhill’s quandary is further complicated by the introduction of Eve Kendall, a beautiful yet mysterious woman he encounters on a train during his escape from the authorities and people trying to kill him. During the dining room scene on the train, Hitchcock expertly uses the camera to convey the characters thoughts and feelings. Interestingly, in a film that has several sequences with complicated cinematography and editing, the dining car scene is†¦show more content†¦Once the flirtations between the two in intensify, Hitchcock transitions into using close shots, beginning when Eve discloses her bribe arranging Thornhill being seated with her, and her subsequent reveal that she knows Thornhill wanted for murder. The use of the close shot provides a better, more intimate view of their expressions as they banter back and forth and the sexual innuendos ramp up. Thornhill’s thoughts are particularly evident across his face as he changes from showing interest in the attractive woman across from him, to tension at being recognized by her, to unabashed glee at the prospect of sleeping with same said beautiful woman, and finally to alarm as he learns police are boarding the train. In contrast to Thornhill’s expressive looks, Hitchcock shows Eve’s as being more controlled and understated. Throughout her linguistic dance with Thornhill, Eve manages to maintain an air of surety about herself, revealing only those pieces of information that she wants him to know. She manages to exude a sense of cool certainty and control during arguably the most sexually suggestive moment of the film: in the only profile shot of the scene, the camera shows Eve as she slowly blows out the flame on the match Thornhill uses to light her cigarette, clasping his hand as she does so. This aura of calm calculation gives the sense that she is in complete control, no doubt dueShow MoreRelatedComparative Analysis Of Vertigo, North By Northwest And Notorious By Alfred Hitchcock1348 Words   |  6 PagesComparative Analysis of Vertigo, North by Northwest and Notorious by Alfred Hitchcock The British master of suspense, Alfred Hitchcock, made the cinematographic history by the unique auteur approach.

Solving The Criminal Mind From A Grander Perspective

The best way to prevent crimes in the community is to have all agencies affected by crime, working together to minimize the influence of it. I call this theory, ONE SYSTEM. The numerous theories mentioned in chapter one of the criminology theory book have one common goal, to understand. Theories such as macro level theories try to explain the criminal mind from a grander perspective. Where micro theories attempt to bring an improved perception on an individual level. Have we mastered the evolution needed to bring change to the social or individual level? I will assess some of the different criminology theories reviewed in class, the pros and cons of the one system theory, that an adequate comparison can be produced of the one system theory. There are numerous theories in place to help understand the criminal mind and to assist with carrying out change. Social structure theory looks at the environment as a whole. Where social processing looks at the procedure the person learns. Social processing looks at the family, and subcultures. You have classification of theory which compact development in a well-ordered bundle. Another theory is classical which emphasis legal reform and the ability to target individually. They are two of the oldest classification theory.

Hence, a manager always has to organize in order to get results. A manager performs organizing function with the help of following steps:- Identification of activities - All the activities which have to be performed in a concern have to be identified first. For example, preparation of accounts, making sales, record keeping, quality control, inventory control, etc. All these activities have to be grouped and classified into units. Departmentally organizing the activities - In this step, the manager tries to combine and group similar and related activities into units or departments. This organization of dividing the whole concern into independent units and departments is called depart mentation. Classifying the authority - Once the departments are made, the manager likes to classify the powers and its extent to the managers. This activity of giving a rank in order to the managerial positions is called hierarchy. The top management is into formulation of policies, the middle level management into departmental supervision and lower level management into supervision of foremen.

The Gospel of Luke Free Essays

The Gospel of Luke like the other three Gospels depicts the life, teachings, death and the resurrection of Jesus of Nazareth. This is the largest of the four Gospels. The Gospel opens with a salutation to Theophilus and proceeds to tell the story of the appearance of Angel Gabriel to Zachariah, whose wife Elizabeth did not have the ability to bear a child. We will write a custom essay sample on The Gospel of Luke or any similar topic only for you Order Now The Angel announces to Zachariah that his wife will bear a child and that â€Å"he will bring back many people of Israel to the Lord their God. He will go as God’s messenger, strong and mighty like the prophet Elijah. He will bring fathers and children again; he will turn the disobedient people back to the way of thinking of the righteous; he will get the Lord’s people ready for him†. The dumb founded Zachariah could not believe the words of the Angel Gabriel. Zachariah was spending a long time in the Temple and when he came out he could not speak. He was punished with the dumbness till the miracle was realized by him. People knew that he had seen a vision in the Temple since he was making signs to them with his hands and unable to say a word. Gabriel then appears before Mary, who was promised in marriage to Joseph and proclaims that the Holy Spirit will come on her and she will give birth to a son who is to be named Jesus. He adds that â€Å"He will be great and will be called the Son of the Most High God† and that the Lord God will make him a king, as his ancestor David was, and he will be the king of the descendants of Jacob for ever and his kingdom will never end†. After a few months Mary visited her cousin Elizabeth, and when Mary greeted her, the baby in Elizabeth’s womb â€Å"jumped with gladness†. In due course Elizabeth gave birth to a baby boy and he was circumcised and named John. Zachariah regained his speech at that time, as he was filled with the Holly Spirit. The baby grew up into John the Baptist. Joseph and Mary went to Becklehem to register their names for the census and ordered by Emperor Augustus. There Mary gave birth to Jesus and laid him in the manger. An Angel announced the birth of Christ to the shepherds. The shepherds visited the Holy Baby and spread the word around. The baby was named Jesus, as preordained, was circumcised, and was taken for the ceremony of purification. There Simeon, a God-fearing man, filled with Holy Spirit, held the baby in his hand and praised the Lord for bringing glory to the people of Israel. When Jesus was twelve years old his parents took him for the Passover ceremony as usual, but that year he did not return with his parents, and stayed back in the temple, with the Jewish teachers listening carefully, and asking intelligent questions. Jesus grew into a boy of great wisdom. While Herod was the ruler of Galilee, John the Baptist was appealing to the people to turn away from their sins and to get baptized. He also preached the Good News that one much greater than him is coming to baptize them with the Holy Spirit. He also spoke critically of Governor Herod and subsequently became imprisoned. When Jesus was about thirty years old the power of the Holy Spirit started radiating from him very powerfully and he was revered and praised by all. The Devil tried his level best to tempt Jesus through many tricks, but Jesus did not succumb to any of the tricks. But when Jesus went to Nazareth to read from the scriptures, He was not appreciated there. There is a saying that the darkest place is under the candle. Nazareth was the place where Jesus had been brought up. Yet people failed to recognize the Holy Spirit emanating from Him. The power embedded in Jesus started performing miracles. At Capernaum, a town in Galilee, He drove away the evil Spirit that had possessed a man. He cured the high fever of Simon’s mother-in-law. Learning about His miraculous powers, sick people started flocking to Jesus. A touch by his hand cured every one of them. He cured a leper of his leprosy. Once a paralyzed man was carried on a bed and brought to Jesus. He told the man that â€Å"your sins are forgiven you, my friend†. The listeners were puzzled by this, thinking that only god can forgive sins. They thought Jesus was impersonating God. The paralyzed man walked back home. Jesus was unconventional in many of his acts. He kept company with outcasts, supported and eating on Sabbath days, and even cured the crippled hand of a man on a Sabbath day. Gradually anger hatred and fear started building up against Jesus among the Pharisees and the teachers of law. Jesus went on healing and teaching the people who flocked to him. He even breathed life into a dead man. He assured the poor and the sorrow-stricken that there is a great reward awaiting them in Heaven. He taught them to shun violence. He spread the gospel of love. He warned people against judging others. Through powerful parables Jesus started driving great ideas into the minds of the people. As time passed, the number of miracles performed by the spiritual power of Jesus grew unbelievably. The fisherman who could not net any fish in spite of a hard day’s labor, caught netfuls of fish at the order of Jesus. A mob of evil spirits had been driven away from a possessed man into a group of swine. He calmed a storm in the ocean with a single command. A woman who had been sick for twelve days touched the robe of Jesus and got cured instantly. He raised from death the daughter of Jairus. Once He fed a crowd of five thousand with just five loaves of bread and two fish. Jesus had gathered His disciples from among the fisherman. He gave them power and authority to drive out demons and to cure diseases. In due course of time He told His disciples about His impending death and resurrection. He recruited more disciples and sent seventy two of them to different towns with the message of God’s love. To the skeptical teacher of law, He gave the parable of the Good Samaritan. He advised the Pharisees to keep their minds clean and worthy. He even told them that they â€Å"are like unmarked graves which people walk on without knowing it. † When one of the teachers of the law protested saying that Jesus was insulting them, Jesus accused them of holding the keys to the house of knowledge, neither themselves going in, nor allowing anybody else to go in. This infuriated the teachers and they wanted to wreak vengeance on Him. In the meanwhile Jesus went on enriching the peoples’ minds through the parables of the Yeast, Mustard Seed, the Narrow Door, the Unfruitful Tree, Faithful and the Unfaithful Servant, the Great Feast, Worthless Salt, the Lost Sheep and many more. His healing miracles continued as ever. He taught the people that the kingdom of God is within themselves. He reminded them that it is harder for a rich man to enter the Kingdom of God than for a camel to go through the eye of the needle. Jesus drove the merchants from the Temple, and warned people to watch out for the Teachers of Law who take advantage of the weak. They wanted to kill Jesus and finally Judas under the devil’s influence agreed to betray Christ. During the Feast of the Unleavened Bread, Jesus broke the bread and gave it to His disciples saying that it was His body, and gave them the wine as new covenant sealed with His blood. He added that â€Å"the one who betrays me is here at the table with me†. Jesus also predicted the denial of Peter. Jesus was arrested after being kissed and identified by Judas, and Peter three times denied knowledge of Him, as predicted by Jesus. The elders of the Jews, the teachers and the Chief Priests asked Him if He was the â€Å" Son of God â€Å" and He answered â€Å" you say that I am â€Å". For claiming Himself to be God, they decided to punish Him and took Him to Pilate. Pilate sent for Herod. Pilate told the crowd that he did not find Jesus guilty, but the crowd shouted that Jesus must be killed. He was nailed on the Cross along with two criminals. At Jesus’ death, noon turned into darkness, and the curtain in the Temple tore into two. His body was received by Joseph of Arimathea and some ladies who were with him and He was buried. But the third day Jesus resurrected, as He had foretold earlier. Jesus later appeared before His disciples and then was taken into heaven. Conclusion: The word Gospel literally means â€Å"Good News†. But the Gospels in the Bible are more than â€Å"Good News†. They belong to the genre of biography and historiography. As biography it races the birth, growth, crucifixion, and resurrection of Jesus. As historiography it draws a continuous line from the scriptures, from Abraham, through Moses, David, and Isaiah to the age of Jesus. The gospel of St. Luke, from another perspective, is the exposition of God. Its power as scripture is simply unique. How to cite The Gospel of Luke, Papers

Treasury and Risk Management Derivatives

Questions: 1.Why futures and options contracts are generically referred to as derivatives?2.What is the difference between a European and an American option, as far as the buyer and the writer are concerned?3.You are a speculator and you think stock prices will increase. Should you buy a call or a put option?4. Under what circumstances would you make a profit at maturity from a long position in a futures contract on live hogs?5.Who might find a futures contract on (the price of) orange juice, useful? Answers: 1. Futures and options are two most general forms of derivatives. A derivative is commonly stated as the financial instrument that receives its significance from the worth of an underlying instrument. The contract prices of futures and options are also determined by the worth of underlying instrument. Therefore, they are commonly referred as derivatives (Golez 2014). 2. The buyer of the put or call option is in a position to take decision about whether to exercise the option or not. On the contrary, the writer holds the passive position and is obliged to go with the decision of the person having long position. In Europe, the option can be exercised only after the maturity date, that is, the expiry date. On the other hand, the person with long position, that is, the holder at any time, can exercise the American option. Therefore, if the person with long position exercises the option only with consideration to his own profit, the writer may have to bear huge losses. The person with long position of a call or put will never bear loss at the maturity of the contract as he always has the option of not exercising the option. However, he has to make the upfront payment for option premium, and if the contract is held to the date of maturity, he will have to bear the maximum amount of loss (Wang, Zhang and Fang 2015). 3. As a speculator, it will be a better option to buy a call as the price of the stock are expected to increase beyond the strike price and will generate profit for the speculator. Here, the seller of the stock fixes the strike price (Schwager and Etzkorn 2017). 4. Suppose, the price of future at the beginning (t = 0) for the contract of futures, which is also known as the delivery price is F0 = $500 per hog. At the expiry date, suppose the hog price is ST = $310. At this point, there are two options. Firstly, the delivery for the hog under the future contract can be taken and payment can be made as F0 = $500. This amount will go for short under the future contract. On the same day, the hog can be taken to the local market can be sold on Spot for ST = $310 and will earn a profit of ($500 - $310) = $190. 5. It is beneficial for the farmers to use the future contract on dealing of orange juice. The reason behind this is that most of the oranges are grown in Florida, where the weather is of disastrous nature. Due to this, the prices of oranges may raise and make it costly for the buyers, which in turn, may results into high supply and low demand. If the weather is favourable and there is no disaster, the price will decrease for the oranges. The competitors from other counties may also lead to price fall. To protect themselves from loss, the farmers will opt for future contract at a fixed price that will prevent them from losses (Glinberg and Landa 2014).
