Here are some videos of the robot.
When the robot first started moving, i put some videos up on Youtube. Here they are-
Here it is just turning on the spot. This tests the motor driver board and the stepper motors to see how quickly they can run.
This video shows the stepper motor acceleration (explained in the Theory page).
Before I had a maze build, i made the robot into a wall avoider. Here are some videos -
This is the robot with very simple bang bang on-off control. When something gets too close to the robot, it stops one motor.
This is the robot with P Control. This time it speeds up and slows down the motors proportionally to the distance an object is away from the mouse.
