Scribbler Robot with Wheel Encoders

A short demonstration of a Parallax Scribbler robot to which I added optical encoders for monitoring wheel rotation. The stock robot cannot drive very straight, travel specific distances or make accurate turns because it doesn't know how fast its wheels are turning. Here, the robot uses its homemade encoders to navigate a simple square pattern and return close to its starting point, a blue mark on the floor. 3 green LEDs on the robot flicker to show which wheel is ahead or behind of the other as the motors speed up and slow down.
