MRA2000

MRA2000 was my first moving robotic arm. If it hit something it would back up and try to pick it up. While doing this it would check twice to see if the sensor on the arm is hitting anything. If it was it would back up and try again. Once it had picked up the object (or try to incase it was a wall or something to heavy) it would back up turn and drop it, then it would back up and turn again then move forward tell it hit something. The two light sensors made the two RCXs beep at different light readings. It was really slow because the drive base was powered by two worm gears. All the sensors were wired to both RCXs.
