This omni-wheel robot has three sonar, three sharp IR rangefinders, and many various pathfinding and object avoidance behaviors.

Created in May of 2004, my goal of this project was to build a robot that can do realtime 2D mapping accurately while going insanely fast.

It uses two Sharp IR rangefinders on a scanning servo to generate a 2D map using a PIC16F877.

In the last scene, you will hear the really loud DC motors on the treaded chassis. I didnt realize it at the time, but the reason it kept spinning clockwise was because a sensor had a loose connection making it work only sometimes. Despite the bad sensor data, it still had zero collisions!
