Hyper Squirrel Robot

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!

wait how exactly does it map though?

do you run the timer and time how long it takes to find a wall and save the time to each turn in eeprom to be read by the computer?

I just added a second link to the info box. It should explain how I did it. Just scroll down to Range Finder Basic 2D Mapping.
