Purpose:
To explore sensors and use them to knock down a box filled with bean bags without going over the edge of a precipice. Hypothesis:
I think that designs with a high point of impact and and sensor placed out in front of the robot will have the best results.

Group 2 | Trial | Distance from the Egde | 1 | 28 mm | 2 | 32 mm | 3 | 35 mm | 4 | 22 mm | 5 | fail | Average | 32 mm |

Competion | Group | Average | 1 | 23 mm | 2 | 32 mm | 3 | fail | 4 | 7 mm |

Program Flow:

1. #Include “Main.h” 2. 3. void main (void) 4. { 5. int limitswitch; 6. 7. // 0 is pressed 8. // 1 is not pressed 9. Wait (5000) 10. while (1==1) 11. { 12. limitswitch = Get DigitalInput (1); 13. if (limitswitch==1) 14. { 15. Set Motor (1.0); 16. Set Motor (10.0); 17. Wait (200) 18. } 19. else 20. } 21. Set Motor (1.-40); 22. Set Motor (10.40); 23. } 24. } 25. }

Results:
Group 1 cam in second place with an average of 23 mm from 5 trials. Group 2 (my group), came in third place with an average of 32 mm from the edge of the table. Group 3 came in last place with one fail and not having completed the rest of the trials yet. Group 4 came in first place with an average of 7 mm from the edge of the table.

Conclusion:
I think that my hypothesis was proved correct since every robot that was successful had both a high point of impact and the sensor at least some distance in front of the robot. I think that an error that my group made was that we did’n allow for enough time to tweak the program and bot together and ended up being, although not aslant minuet as the last lab,

...Introduction to Information Systems 3.6 – Analysis Short Paper Exercise Publication Summary This report will provide a brief summary of an article titled, “Smart Powered Wheelchair Platform Design and Control for People with Severe Disabilities” by Youcef Touati, Arab Ali-Cherif (Computer Science & Artificial Intelligence Lab. LIASD, University of Paris 8, Saint-Denis, 93526, France), published on Scientific and Academic Publishing’s website. The author explains the development of innovative systems for the disabled and elderly based on new technology according to individual needs. Research from medical, paramedical, and advanced technology fields contributed to the development of new strategies, which contribute to a role in helping the disabled and elderly live more autonomously [1,2]. The design ensures reliability of an interactive, powered wheelchair with obstacle avoidance capability in a constrained environment, though methods such as edge detection [3], potential field [4] and impedance control [5]. The principle is to generate a virtual force between mobile system and environment using exteroceptive (relating to, being, or activated by stimuli received by an organism from outside) localization tools such as Ultrasonic (US) sensors, Light Detection and Ranging (LIDAR), a Wireless Internet Camera Server (WICS), and onboard processing. The wheelchair can be controlled and monitored using a force-feedback joystick. Generated virtual forces are transferred...

Abstract This paper presents solutions for one requirement of autonomous characters in animation and games: the ability to navigate around their world in a life-like and improvisational manner. These “steering behaviors” are largely independent of the particulars of the character’s means of locomotion. Combinations of steering behaviors can be used to achieve higher level goals This paper divides motion behavior into three levels. It will focus on the (For example: get from here to there while avoiding obstacles, follow this corridor, join that group of characters...) middle level of steering behaviors, briefly describe the lower level of locomotion, and touch lightly on the higher level of goal setting and strategy. Introduction Autonomous characters are a type of autonomous agent intended for use in computer animation and interactive media such as games and virtual reality. These agents represent a This stands...

...elements. This matter clumped together under its own gravitational pull to form clouds. Within these clouds, scientists think hydrogen atoms (which contain one proton and one electron) bonded with negatively charged hydrogen ions (one proton and two electrons) to form molecular hydrogen, consisting of two hydrogen atoms chemically bonded. This chemical reaction served to cool and condense the clouds until they were dense enough to ignite nuclear fusion, the process that powers stars. Theorists had predicted this chemical reaction, but had trouble calculating just how it would happen and how quickly.

...System Engineering Management ROBOT PAINTING USING ARTIFICIAL INTELLIGENCE SUBMITTED BY Hari priya Kapileswarapu 1504606 ADVISOR Steven Maher; Geoffrey Rodman OKLAHOMA CHRISTIAN UNIVERSITY ABTRACT: This paper describes about one the functionality of the robot and how robot paints an object using artificial intelligence. And objects like iron wall, wooden box, motor bike etc. Suppose if the robot has to paint a motor bike it has to identify the parts of the motor bike and has to paint the color to those parts. For example, if the rims of the wheels had to be painted in black color then the robot has to identify the rims and paint the black color. In the same way, if the chassis had to be painted with black color then the robot has to identify the chassis and paint it accordingly. In this way, the whole motor bike would be painted by the robot based on the parts. For painting the parts of the motor bike there are some methods like generating the optimum path and the trajectory methods. In this way, robot can paint the respective object based on the models with different colors.

...Robotic Assistants for Aircraft Inspectors Mel Siegel, Priyan Gunatilake, and Gregg Podnar Intelligent Sensor, Measurement, and Control Laboratory The Robotics Institute -- School of Computer Science -- Carnegie Mellon University Pittsburgh, Pennsylvania 15213-3891 ABSTRACT Aircraft ﬂight pressurization/depressurization cycling causes the skin to inﬂate and deﬂate, stressing it around the rivets that fasten it to the airframe. The resulting strain, exacerbated by corrosion, drives the growth of initially microscopic cracks. To avoid catastrophe, aircraft are inspected periodically for cracks and corrosion. The inspection technology employed is ~90% naked-eye vision. We have developed and demonstrated robotic deployment of both remote enhanced 3D-stereoscopic video instrumentation for visual inspection and remote eddy current probes for instrumented inspection. This article describes the aircraft skin inspection application, how robotic deployment may alleviate human performance problems and workplace hazards during inspection, practical robotic deployment systems, their instrumentation packages, and our progress toward developing image enhancement and understanding techniques that could help aircraft inspectors to ﬁnd cracks, corrosion, and other visually detectable damage.

#### Brain Controled Wheel Chair

...Brain-Controlled Wheelchairs A Robotic Architecture By Tom Carlson and José del R. Millán © photodisc & techpool studios I ndependent mobility is central to being able to perform activities of daily living by oneself. However, power wheelchairs are not an option for many people who, due to severe motor disabilities, are unable to use conventional controls. For some of these people, noninvasive brain– computer interfaces (BCIs) offer a promising solution to this interaction problem. Brain-Actuated Wheelchairs Millions of people around the world suffer from mobility impairments, with hundreds of thousands of them relying on power wheelchairs for activities of daily living [1]. However, many patients are not prescribed power wheelchairs either because they are physically unable to control the chair using a conventional interface or because they are deemed incapable of safely operating them [2]. Consequently, it has been estimated that between 1.4 and 2.1 million wheelchair users might benefit from a smart-powered wheelchair if it were able to provide a degree of additional assistance to the driver [3]. Digital Object Identifier 10.1109/MRA.2012.2229936 Date of publication: 8 March 2013 In our research with brain-actuated wheelchairs, we target a population that is or will become unable to use conventional interfaces due to severe motor disabilities. Noninvasive BCIs offer a promising new interaction modality that does not rely on a fully functional peripheral nervous...

Nature has always inspired human achievements and has led to effective materials, structures, tools, mechanisms, processes, algorithms, methods, systems, and many other beneﬁts (Bar-Cohen Y (ed) 2005 Biomimetics—Biologically Inspired Technologies (Boca Raton, FL: CRC Press) pp 1–552). This ﬁeld, which is known as biomimetics, offers enormous potential for inspiring new capabilities for exciting future technologies. There are numerous examples of biomimetic successes that involve making simple copies, such as the use of ﬁns for swimming. Others examples involved greater mimicking complexity including the mastery of ﬂying that became possible only after the principles of aerodynamics were better understood. Some commercial implementations of biomimetics, including robotic toys and movie subjects, are increasingly appearing and behaving like living creatures. More substantial beneﬁts of biomimetics include the development of prosthetics that closely mimic real limbs...
