description This robot was designed to possibly compete in the MicroMouse competition or just to experiment with. For MicroMouse general info see http://nis-www.lanl.gov/robot/html/rules/micromouse.html Functions I tried to create this robot based on the Lego theory of being able to interchange parts (in this case sensors) to suit the task of the robot. I created modules of sensors (light detectors, sonar, IR, whiskers or switched, potentiometers and others)that can be inserted on any I/O of the Cricket board and depending on the software it would have different reactions to its environment. This allows me to experiment more and test for different scenarios. The robot will be able to do collision avoidance, light tracking/avoidance and other random behaviors Specifications small - smaller than a CD. Appox 10cm x 11cm Parts used Many parts from the Digi-Key catalog, including Plexiglass for the chassis, plastic and metal stand-offs, nicad batteries, old (very old) servos, tires from an old 1980's toy, and most important the Cricket Microcontroller and IR Whiskers - detects left and right obstacles for collision avoidance (soon to be installed, not shown on picture) For information on this excellent and mulitfunctional board see: http://home.earthlink.net/~henryarnold/ The board was originally designed for a cricket robot, but it can be easily modified to work on any kind of robot. Problems encountered Since the servos I used are very old, they were more difficult to modify and calibrate to work with the new electronics that I interfaced it with. Time to build 3 weeks (2 to 3 nights a week) Cost $180 Any other important information The robot is not complete but it will be by the middle of April Web site URL http://www.csulb.edu/~wmartinz Email: wmartinz@csulb.edu
