RoboShape: The Drawing Robot ABSTRACT For our final project, we have chosen to build a robot, using the Legos Mindstorm kit. It will be programmed using NQC. The name of the robot is Roboshape. It is comprised of two main structures; a rectangular base, which is the y axis, and a black log, which is the x axis and moves along the y axis. Our robot uses a light sensor to scan in a certain colored piece of paper, and using this percentage input, it will print out the desired shape. BACKGROUND/PURPOSE Every child has their own unique approach to learning. While some can easily comprehend information by just listening, the majority of adolescents need a visual example to fully understand a specified subject. Being able to associate their much loved colors to shapes would greatly improve a child?s desire and enthusiasm towards learning. We are proposing a robot that will use one RCX to scan in colored strips of paper and reflect a certain percentage of light. This percentage of light will then be transmitted to a second RCX, which will use its stored program to print out a particular shape. Though we are building a robot, it will mainly be used as a toy and a learning tool. Parents and kindergarten teachers are the main consumers that this product will be directed at. I was able to locate a similar robot to the one that we are planning to construct. It is called the Geo-bot and is used to draw polygons and other shapes. It requires the use of a two motor design, where one motor drives each wheel or tread. Our project is different in that the Geo-bot merely drives out the shapes, while ours will use motors and rotational sensors to direct and move pens to draw out shapes. BACKGROUND/PURPOSE Research shows tha... ... middle of paper ... ...itching. The great difference in speed, the y-axis moves much slower than the x-axis, affects the overall performance of the robot, making it even more unreliable. If expanded upon, the gear reduction could be changed so that a much more desirable ratio can be achieved. With more time we can also construct a series of gear that would raise the pen, enabling us to draw more efficiently and even allow us to write a letter or words. REFERENCE Baum, David.

For the construction of the robot, only the Lego pieces and sensors provided in the tackle box were used. The design of the robot was modified from the original versions however, with the following specifications. The wheels were positioned in the front part of the robot, thus changing the axis of rotation to the front of the robot when it turned. Instead of the conventional four wheel design, the two rear wheels were replaced with a single pivoting wheel, thus reducing the resistance when turning. Finally, an ultrasonic sensor and sound sensor were mounted at the front of the robot as shown in Figure 2.

Zeus, Crowder’s first robot, runs on a 9-volt battery, was solar powered, and has a “brain” composed of three neurons and a communication hub. Zeus was shape was inspired by a cockroach and given simple knowledge. Zeus was programmed to feel ‘pain’ from being exposed to light and and that it can moved its body. Eventually it learned to walk and that it ran with solar power. This created a paradox for the intelligent robot. Zeus needed light to recharge its batteries when it ran low but it was programmed to avoid light like it hurt them. Crowder mentioned this paradox was emotion-like for this intelligent robot. The conflict made the robot learn from its emotions and artificial survival instincts. Emotions can help artificial intelligent robots learn and adapt. This simple setup for artificial intelligent robot but it is a start to understanding how to program a robot to think intelligently and

During middle school, my interest in creating things had sparked brighter than ever. Each creation kept me rolling down the same path. As I got more advanced, each set presented new challenges. After years of watching me enthralled in building custom sets, my dad enrolled me into a Lego Robotics tournament. One magical idea kept jumping to the next. What would I build? What task would I complete? From that point forward, I devoted every Saturday morning

First off, CAD is computer technology that has contributed in design and drafting of a portion or an artifact and frequently a complete structure as well. Computer aided drafting software is identified as CAD. It is fascinating and intriguing software because we can assemble a 3-D detailed view and that is very challenging to envision without CAD. “The two essential categories of computer aided design software are two dimensional and three dimensional. Here are a few types of CAD, Turbo Cad, IntelliCad, StrucCad, and Solidworks. Some advantages of CAD are precise drawings in dimensions, enhanced info flow via email, simplified project documentation, effortless and systematic archiving of CAD drawings, reduced retrieval time of electronic files, minimal probabilities of harm or information loss.” (Benefits of Computer Aided Drafting software and CAD applications), (2011).
A robot can be autonomous or semiautonomous. There are two main type of a robot it either robot by application or robot by locomotion, most Application robot are used in the military, domestically, Industrial, medical, hobby, and space. A robot might be legged for example the robot manipulator FD-500 this kind of robots is used in car assembling lifting of heavy

This step begins with an analysis of the design solutions and moves on to functional analysis, examination of ergonomics, a review of product safety and liability, economic and market analysis, mechanical/strength analysis, and finally, vetting the chosen solution through the decision process. The fourth step of the robotic design process is to simply "build the robot", this is considered it's own step as the assembly of said robot could take weeks, months, or even years depending upon parts availability, systems correlations, and any unexpected negative results during
Robots have been around for less than fifty years, but the idea of metal creations that do our bidding is much older. The ancient Greek poet Homer described maidens of gold, mechanical helpers built by Hephaistos, the Greek god of metal smiths. The golems of medieval Jewish legend were robot-like servants made of clay, brought to life by a spoken charm. In 1495, Leonardo da Vinci drew plans for a mechanical man. However, real robots wouldn’t become possible until the 1950s and 1960s, with the invention of transistors and integrated circuits. Compact, reliable electronics and a growing computer industry added brains to already existing machines. In 1959, researchers demonstrated the possibility of robotic manufacturing when they unveiled a computer-controlled milling machine that made ashtrays.
My undergraduate course in the field of Electronics Engineering has given me a comprehensive exposure to all the core fields of computer science and mathematics. In my junior year, I participated in the prestigious robotic contest-Robocon 2007 with my peers. It was an eye-opening experience as I got an opportunity to manufacture a robot from scratch– from designing, assembling to programming. I was extensively involved in programming it, using C++ language for path planning and motion control. During this phase, I learned about different algorithmic strategies like Line and Sensor-based Algorithm, Fuzzy Logic etc. that could help the robot decide faster navigation and make correct decisions to avoid getting blocked kindling my interest in that area. Overall, it was a great learning and challenging experience as it gave me an insight into how the concepts of different branches of engineering culminate to make a robot and required a host of activities including problem solving, research and team-coordination to achieve our goal.

The use of robot has created a great impact on human lives and made them easier. Today human efforts have been reduced so much that all heavy load work can be done with the help of robots. Robots often use computer systems for their control, sensory feedback, and information
