Meteorite or Puck Hunt Autonomous Mobile Robot

Advertising We will write a custom report sample on Meteorite or Puck Hunt: Autonomous Mobile Robot specifically for you for only $16.05 $11/page Learn More Introduction The creation of the autonomous mobile robot (AMB) project is the most important branch of the unit, HES 1305 ROBOTICS AND MECHATRONICS PROJECT 2. The plan, design, building, programming, testing, as well as debugging the different components of the project, would involve teams which consist of three members. The purpose of the autonomous mobile robot would be to travel through a maze while avoiding going over the wall of the maze. In addition, the AMB would also be required to look for certain types of â€Å"pucks or meteorites† that would be identified by their colours, in a mission, which is simulated, in Antarctica. As a result of the intricacies of the predicted settings, the AMB would be required to carry and place the meteorites or pucks in their respective base camps; they should not be thrown or rolled on the ground. In addition, the robots would not be allowed to get rid of unwanted pucks from the camps, or destroy other robots. The project is in fact a competition pitting different teams against one another. Each team would provide one robot in the competition area to collect as many meteorites and place them in the specified camps. The teachers and staff of Swinburne University provided all the sensors, LEGO parts, software, and actuators. The Method Of Design Design Philosophy One vital building block of artificial intelligence involves creation of a robot that has the ability to function under diverse and indeterminate environments, while under partial supervision. The Development of the Design Being the first time that we are taking part in this type of competition, we decide to work out a plan that would help us develop the autonomous mobile robot in the given surroundings.Advertising Looking for report on other technology?

After that, we had to go backwards with the intention of building a structure that could support all the equipment, actuators, and sensors, in order to produce a practical robot in the contest atmosphere. Design Process Hardware Part – (Name of Team member who handled this part) Handy board Autonomous robot control is usually attained by means of a Handy Board [Martin 2001]. The Handy Board was found to be a battery-powered and hand-held microcontroller board. It was perfect for both educational and personal robotics projects. It was based on the structure and functions of the Motorola 68HC11 microprocessor. Figure I The Handy Board contained the following parts: Processor: Motorola 68HC11 8-bit microcontroller with 2MHz speed RAM: 32KB battery-backed fixed RAM Scree n: 16Ãâ€"2 character LCD display unit Four 1A motors support 6 Servo motor controllers 9 Analog and 7 Digital inputs 16 Analog and 8 Digital outputs Infrared I/O capabilities Serial interface capacities Sound output 11cm x 8.5cm x 5.25 cm (L x W x H – with LCD screen, expansion board, and battery) Figure IIAdvertising We will write a custom report sample on Meteorite or Puck Hunt: Autonomous Mobile Robot specifically for you for only $16.05 $11/page Learn More The Handy Board manages Interactive C (IC). The Interactive C is a custom-made version of ANSI C programming language. Interactive C is the most widely held compiler software that is made use of with the Handy Board. In addition, the Interactive C software is a multi-tasking compiler; it has a user command line that is used for dynamic expression evaluation and compilation (Martin, 2001). The IC is sustained by the Kiss Institute for Practical Robotics (KIPR). The figure above (figure II ), demonstrates the running of the IC compiler on Windows XP. Procedure followed for programming the Handy Board using Interactive C Step 1: The Handy Board was connected to the computer using either the Serial Interface or the USB. Step 2: The wall adapter was then used to supply power to the Handy Board. Step 3: Afterwards, the Interactive C compiler software was launched on the computer. Step 4: The board was then initialized with firmware. This was achieved by holding Handy board in a unique bootstrap download mode and then clicking on the download firmware found on the tools menu of the IC compiler software.Advertising Looking for report on other technology? Let's see if we can help you! Get your first paper with 15% OFF Learn More Step 5: After completion of downloading the firmware, the Handy Board beeped, and the Interactive C welcome message appeared on the LCD screen of the Handy Board. This means that the Interactive C is now ready for use. After finishing configuring the system, we are now ready to write the necessary programs using Interactive C IDE software. Then later, we would compile it, and after that download it on to the Handy Board that will run that program. Sensors Each LEGO kit was supplied with the following sensors: Item Quantity Red LED 1 Blue LED 1 Phototransistor 4 Servo Motor 1 IR(Infra Red) Emitter/Detector 2 Micro switch 4 Combined Lego Motor Gearbox 4 Potentiometer 2 IR Range Finder (Sharp GP2D02) 1 Shaft Encoder 2 Table I Out of all these sensors, our interest and use will be limited to Combined Lego Motor Gearbox, Micro switch, Shaft Encoder, Phototransistor, LEDs, as well as IR Emitter/Detector. LED is the short form of a light-emitting diode. Just lik e the name suggests, an LED is basically a diode that gives off light. The difference between LEDs and other incandescent bulbs: LEDs are different from ordinary incandescent bulbs in the sense that they are short of a filament, which burns out. As a result, they do not get especially hot. They are solely lighted up by the motion of electrons in a semiconducting material. In addition, they could last as long as a typical transistor. Advantages: The use of LEDs endows the user with a number of advantages in comparison to the use of regular incandescent sources of light. Some of these advantages include enhanced robustness, lower consumption of energy, longer lifetime, greater durability, smaller size, improved reliability and faster switching (Jones, Flynn Seiger. 1999; Papert Harel, 1991). How LEDs work? Figure III When an LED is switched on, i.e. forward biased, electrons in the PN Junction are capable of recombining with the holes found within the device. As a result, energy is released in the form of photons. Consequently, the energy gap of the semiconductor has some bearing on the colour of the light, or the wavelength of the radiation. This is to mean that doping has some bearing on the wavelength of the Electromagnetic radiation which will be given off. In general, light-emitting diodes are usually made from substrates of Aluminium-gallium-arsenide (AlGaAs). From Electromagnetic spectrum, the wavelength for red is normally between 620 and 750 nm, while that for blue is between 450 and 475 nm. In other words, Red LED and Blue LED means that their doping components are such that the emitted wavelengths range between 620 and 750 nm, and between 450 and 475 nm in that order. Figure IV LEDs have two major uses; visual indicators and light emitters. As visual indicators, they detect the presence of things. When used as light emitters, they are usually detected by other detectors, such as phototransistors and photodiodes. Interestingly, they can be used as narrow band light sensors. Here, they operate in the reverse-bias mode. They act in response to incident light as opposed to emitting light. Phototransistor: Figure V A phototransistor can be described as a transistor that operates differently from common transistors. Unlike common transistors, whose operation modes are under the control of the applied input voltage, the operation mode of the phototransistor is can be directed by light, or the wavelength of the light. The structure of a phototransistor varies from that of a common transistor, at least in two distinct ways; While the phototransistor has a transparent window that allows light to shine on the junctions, ordinary transistors do not have such windows. An ordinary transistor has more surface area than a phototransistor, hence is able to maximize the area of light capture. When the junction is struck by light photons, there is formation of a base current. As a result, the received power is converted into a collector cur rent by the phototransistor. The phototransistor that comes with the LEGO kit has its peak response at 850 nm and its spectral sensitivity is higher than 30 per cent for light radiation that ranges between 6oo nm and 900 nm. The achievement of different gain and frequency of operation (bandwidth) is dependent on the amplifiers, or circuits, formed with these phototransistors. The positive thing that is exhibited is that the frequency and gain response is reliant on the light and its wavelength. Infra Red (IR) Emitter/Detector: The infrared emitter or detector is a circuit that is created using LEDs and phototransistors (Martin, 1994). The purpose of the IR emitter/detector is either to give off or to detect infrared radiation. An extremely fundamental infra red emitter/detector circuit is shown and described below. Figure VI This custom made circuit has one disadvantage; the use of this custom made circuit means that the ambient infra red light would constrain its detecting devices (Martin, 1994). The IR emitter/Detector that came with the LEGO kit had its peak response at 940 nm, with peak sensitivity for about 880 nm wavelengths. The IR Emitter/Detector has found many uses in robotics; it can be used for colour detection, transmitters, motion detection, obstacle detection, and encoders. Shaft Encoder: Shaft encoders can also be referred to as rotary encoders. In essence, it is an electro-mechanical piece of equipment that translates the total amount of mechanical rotation, or angle, into a corresponding amount of current (Sutton Barto, 1998). As a result, knowledge in relation to the amount of current offers information regarding the amount of rotation of the shaft, or the wheel connected to the shaft. In general, there exists, two kinds of shaft or rotary encoders; Absolute shaft encoders These types of encoders are the ones that provide us with information regarding the complete angle of rotation of the shaft. The digital type of absolute shaft encode rs generates distinctive digital code for each different angle of the shaft. There exist two fundamental kinds of absolute digital rotary encoders. These are optical encoders and mechanical encoders. Incremental shaft encoders These types of rotary encoders are the ones that provide us with information regarding the angles or rotations with regard to their previous states. The angles of rotation that are provided by the shaft encoders are in coded form. The two available and most popular methods used for encoding are Gray encoding and standard binary encoding. It is worth noting that for all advanced jobs, which involve the rotation of the wheel, there must be a feedback mechanism that comes from the wheels. As a result, it is vital that the control program is aware of the extent to which the wheel would rotate to with the intention of either altering the speed of rotation of the different wheels, or simply making sure that the vehicle is motionless and no unknown force is acti ng on it. This is basically the reason why shaft encoders are employed. Micro switch: Figure VII A micro switch can also be referred to by its technical name, miniature snap-action switch. As implied by its name, the micro switch is a switch that calls for a comparatively miniature movement of the actuator button, with the intention of producing a relatively large amount of high velocity motion of the electrical contacts in spite of the speed of actuation. Micro switches are popular and their use is widespread. This is attributed to their relatively low cost, as well as high durability. They undergo more than one million cycles; for heavy duty models, this may go up to ten million cycles. There are many places and gadgets that require micro switches for proper functioning. Some of these areas include machinery, vehicles, industrial controls, appliances, and numerous other areas for control of electrical circuits. Some common but particular areas where micro switches are employed in clude the door interlock systems on microwave ovens, safety and levelling switches in elevators, detection of faults in photocopiers, such as paper jams, and vending machines. Miniature snap-action switches are frequently made use of in tamper switches on gate valves of fire sprinkler systems, in addition to other water piping systems. In this application, it is vital to be conscious of whether valve has been shut, or it is open. Combined Lego Motor Gearbox: Figure VIII There are DC motors that were provided in Lego kit. These motors are great for building robots in view of the fact that they are powerful and compact. They normally rotate at thousands of rotations per minute. Nevertheless, most electric motors are in actual fact lacking in torque. In other words, this can be attributed to the fact that they cannot push incredibly hard. If hooked directly up to the motor’s shaft, we can note that it can hardly rotate the wheel, let alone nudge a whole robot. Despite the fact that they have inadequate torque, what they do have in plenty, is speed. In reality, if the shaft is running freely, it can rotate at a rate of numerous thousands revolutions per minute. As a result, this speed is much faster than what one wants for a robot to drive in any case. Therefore, we could do with gearboxes with the intention of trading some of this unnecessary speed for additional torque. Figure IX The LEGO system is composed of a wide range of gears with varying functions (Brooks, 1986). On the other hand, for universal purposes, 8, 24, and 40-tooth gears can be employed. These are the easiest and most efficient to utilize of the group for the reason that their diameters are selected, such that they can be interlocked with one another at standard LEGO distances. Through gear reductions, one is able to translate speed into torque (or the other way round by application of this technique in reverse). Suppose an 8-tooth gear is employed in turning a 24-tooth gear. Given tha t the smaller gear is required to rotate three times in order to turn the large gear once, the axle with the 8-tooth gear spins faster than the other. As a result of this exchange for this reduction in speed, the axle is now able to apply three times as much torque. Consequently, this generates a gear reduction ratio of 3:1. This implies that we are relinquishing a factor of three of speed and swapping it over for production of three times the torque. Lego parts Figure X Each component of the LEGO has its work cut out for it (Overmars. 2000). A number of those components are available and are simply used to join two parts that are not able to be stick together with one another. A number of other parts, for instance rollers, are supposed to hook up the wheels with a few other parts of the robot with the intention of making the wheels move with mush ease. What is more, a number of parts are large in size, which could be utilized as the base of the robot; therefore, we could place man y parts on. In addition, they could be used to connect parts that are relatively far away in distance from each other. A good number of the components that we employed in the creation of our robot were the thick red bars and long red bars that assisted us in connection between the wheels. Into the bargain, we used the big bars that have a large area to make use of it as the base of our robot. Furthermore, we could include on those big bars with the broad areas handy board, the battery, and a number of small components that could furnish a better look to our robot. In addition, we made use of the linking parts to a large extent that is on grey to join the parts which we experienced a few difficulties in connecting them together. Assembly Part – (Name of team member who did this part) Grabbing Mechanism The hardest part of the whole project was finding a solution to the problem of grabbing flip over the puck. So as to come across a superior and realistic arm, we stumbled upon a possible like way out on the internet (Williamson, 1998). The ultimate form of the grabbing piece of equipment has two motors; the work of one of the motors was to spin the arm, while the other motor had to push the meteorite aside. Chassis The chassis had to have enough strong in order to give support to handy board, batteries, and all the other sensors that the robot needed. Figure XI Sensors (Name of team member who did this part) It is worth noting that sensors are the most significant components of the robot (â€Å"How to Make a Robot – Lesson 7: Using Sensors†, 2011). When robots have them, they are able to feel, look at and make out the disparity in their surroundings. To enable the robot to verify whether there existed a puck or meteorite in the vicinity of the loading area, we employed one blue led as well as one phototransistor. The purpose of the blue LED was to give off a light beam that would be used by the phototransistor. There are cases when the beam light would be broken; this means that a puck or meteorite is in the loading region. After verifying this and finding a puck in the region, the function of the second phototransistor was to verify the colour of the puck. Readings ranged from 50 to 185 for the red puck. On the other hand, readings were larger than 200 for blue puck. The function of the third phototransistor was to rummage around for the base light with the intention of finding a way back to the base. In case the indicated value was less than 10, this showed the correct direction to the base. An infra red (IR) emitter/detector was made use of with the purpose of determining the exact location of the base. In case the indicated value was higher than 236, then the location of the black line and subsequently, the location of the goal area was illustrated. In addition, the Infra red (IR) range finder was employed in the verification of the ultimate position of the goal area. Lastly, the 4 micro switches were used to †Å"feel† the obstacles as the robot moved around. Motors and the Motor drive mechanism As a result of restriction on the available materials and constituent parts of LEGO, the drive mechanism was made to order for two motors. Figure XII The steering mechanism of the robot was very heavy. The robot used big wheels at the front, and small ones at the rear. The option of making use of rear small wheels was attributed to minimising friction, as well as having a good manoeuvrability. The robot created had major strength; it was very robust. The robustness of the robot ensured that it continued to manoeuvre in every environment it was subjected to. Conclusion This project report has covered all the things the team worked on in the hope of producing a successful robot. In addition, the report also looked at the constituent parts that were used to create the robot, and how the team employed them with the aim of building a physically powerful and innovative robot that could not be easi ly damaged or broken. In addition to that, the project report offers a number of concise ideas in relation to the Interactive C (IC) program and the Handy board. The IC program was used to program the robot so that it could be able to perform the mission as the team wanted it to do. I believe that this activity was an extremely interesting experience. The fact that were could be responsible for creation of a robot that could do a fine job by holding a verifying, collecting and putting a puck in its rightful place as the required by the task. The only initial challenge we faced was the manner in which we could thrust the arms of the robot into the exact place, and how the team could make them turn. This was soon overcome and the team successfully completed the task. References Brooks. R.A. (1986) A robust layered control system for a mobile robot.

Community in Two Novels essays

Community in Two Novels essays Community is often thought of as a town, city, or even neighborhood, but community can refer to just about any group who has common beliefs, common values, or some sort of commonality. Families are small communities, and so are schools, churches, and groups with like ideals or causes. Both of these novels concern communities, and how many of the novels' characters interact with communities, both small and large. Communities are made up of individuals, but unless the individuals conform to community standards, or feel comfortable with them, they will have an uneasy relationship with the community, and with themselves, just as these two novels so graphically illustrate. Both main characters in these novels have uneasy relationships with their family, which translate into uneasy relationships within their small community, and thus translate to uneasy relationships with their larger community. In "The Wars," Robert's estrangement from his family begins with the death of his sister Rowena, and his decision to join the army to fight in Europe, as this passage illustrates, "'You think Rowena belonged to you. Well I'm here to tell you, Robert no one belongs to anyone. We're all cut off at birth with a knife and left at the mercy of strangers. You hear that' Strangers. (Findley 23). Immediately the reader understands the depth of the division in the family, and how Robert is struggling with his identity in his small familial community, just as his mother, Mrs. Ross, will struggle with her identity in the larger community where they live after he leaves. Part of successful assimilation in a community is feeling comfortable and that you belong. In this case, Robert feels he has nothing in common with his mother, and so, leaves the family because the member he loved the most is gone. He is searching for himself, meaning in his life, and attempting to discover where he fits i...

A Modest Proposal With A New Critical Approach Essay -- Johnathan Swif

A Modest Proposal, by Jonathon Swift is very much an ironic persuasive essay. He is proposing the eating of babies as a way to help with poverty. Throughout the essay he makes many thought-out yet almost unthinkable arguments that support his proposal. You do however know he doesn't really want people to start eating babies. He is just trying to show a major problem in a shocking way. His arguments for the eating of babies are as follows: it would greatly reduce the number of poverty stricken people (especially children); it would give those same people income when they sold their children; the nation as a whole will have more money because of this new income; there would be more food for everyone (baby might even become a delicacy); people would save a lot of money by not having to support their children after the first year of birth; and finally, it would help out marriages since there would be less stress on the parents. These theories are stated and supported throughout Swift's essay. He uses the structure of the essay to help you get a good understanding of the material he is presenting. The basic structure of the essay starts out with him explaining the problem he plans to help solve, that Dublin is poverty stricken. There are too many beggars with way too many children. Next, he starts to subtly drop hints about his proposal. He explains that he is going to, "Humbly propose (his) own thoughts," and that he hopes they, "Will not be liable to the least objection."(Abcarian, 629) He continues by further explaining some of his proposal's benefits, then in a list fashion states the six main arguments for it. Swift then adds his last few reasons why people should consider h t before he is about to say something horrible. This is ironic because it is not expected. The speaker has just totally changed his tone. The biggest use of irony is situational irony. The whole proposal is absurd and the speaker kn ows it. He is proposing the idea to show the larger picture. That there is no solution to this problem, and no one has any useful ideas. The eating of babies is utterly outlandish which is precisely why he chose it. The speaker of this modest proposal uses irony to create a tension that helps to convey a certain message. That message is that even though this may be a totally outrageous proposal, no one can complain or judge until they have a proposal of their own. Works Cited Fish,Tom.

Worldview Beliefs Essay Example | Topics and Well Written Essays - 1250 words

Worldview Beliefs - Essay Example This essay demonstrates and shows that what a person looks like at the present does not matter because as we age, our looks also change so that although we may have once been physically beautiful, with time, this beauty is eroded by age and what is left behind is a shadow of what we once were. However, I believe that inner beauty lasts forever because our character and our actions tend not to change as fast as our physical beauty does. An example of this is the way people care for others and one of these is my best friend who has influenced my worldview on this matter. She is a kind, loving, and helpful person and she has the ability to make others feel better, which makes her a treasured friend to have. In conclusion, I believe that the world would be a better place if only all of us could treat each other with respect and tolerance. We should seek to understand and appreciate that people have diverse opinions due to their backgrounds and experiences in life before passing any judgm ent, as this would stop many of the prejudices which some of us have against others. In addition, I am of the opinion that for people to experience greater success in life they have to develop the virtue of perseverance considering that every undertaking has its challenges. In addition, inner beauty, as opposed to the physical outer beauty, is very important since it outlasts the later. Moreover, inner beauty concerns inherent good characters other than the outward impression, which is often deceiving.... Doing so has also helped me to develop very close friendships with people who I would otherwise have not have had any time for and this has ensured that I have developed friendships which have filled my life. It has enabled me to develop the necessary social skills to interact confidently with people from different backgrounds on an equal basis without any feeling of superiority on my part. Many people consider the ability not to give up or perseverance a virtue and in fact, the majority of the world religions encourage it in their followers. Perseverance, from ancient times, has been one of the keys to success and it is very difficult to achieve any level of success without it. I believe that it involves the ability to be committed to a task that one has set for him or herself, to be able to work hard towards it, and to have the patience and endurance to make sure that this task is fulfilled satisfactorily. Never giving up also involves the ability to be able to bear the difficultie s that one is facing calmly and without any complaint because these tend to explain why many fail to succeed in whatever they are doing. A good example of perseverance is the one that the Wright Brothers had when they were attempting to make a flying machine. Many people had no faith that they would be able to make it and in fact, some even tried to discourage their attempts. Despite all this, the Wright brothers became even more determined to achieve their goal, it is this ability of never giving up that made them create the first airplane, and that is why we are able to travel by air today. There are many definitions of beauty but one of the most of these definitions tends to be based on the physical

Norplan - The 5 Year Birth Control :: Contraceptives, Birth Control Essays

Norplant are Six thin, bendable plastic implants that are put in under the skin of the upper arm. These soft capsules are the size of a small stick. Each capsule contains one hormone. Those hormones are called levonorgestrel. Levonorgestrel is like the progesterone that is made by a woman's ovaries. A very small amount of hormone is released regularly. This hormone typically stops the ovaries from getting released. It also condenses the cervical mucus, keeping all sperm from getting together with egg. Some scientist believes that Norplant stops the fertilized egg from sticking to the lining of the uterus. Norplant only last about five years. The Cost of Norplant costs between $500 and $750 dollars. This cost includes the medical exam, a pregnancy test, the implants, and the insertion of Norplant. The cost is about $150 a year for a five-year period. The Doctor will eventually charge an additional fee in order to remove the Norplant her body and that costs from $100 to $200.Some insurance plans may cover Norplant. Norplant is one of the most effective birth control. It becomes effectual in 24 hours of insertion. Out of 10,000 women that get Norplant 5 will get pregnant. Norplant is more effective than sterilization Norplant does not protect women from sexually transmitted infection. The process of inserting Norplant starts with the doctor washing the skin with an antiseptic and she will numb a small area under your arm with a painkiller. The doctor will then make a small cut. Then the doctor will insert six capsules. The person needs all six capsules to prevent a pregnancy. The Insertion takes about 10 minutes. This procedure is painless. The only pain that a person get is by the needle is used to insert the painkiller. Some women have a little bit of discomfort just for a little while it can be inserted at any time of the month even though they usually insert Norplant during the first seven days of a menstrual cycle. This is just to be sure that the women are not pregnant. Norplant must be removed by five years when it stops working. Removal has to occur after five years because if not the hormones may continue to be released and cause irregular periods without pregnancy prevention. To remove Norplant your doctor will numb the area with a painkiller. And he or she will make a small cut will in order to remove all of the capsules.
