Here's the demonstration of the new single axis robotic arm I developed. It's a simple deign that's suitable for entry level robotics competitions. In this case, the CheapBot robot is combining a line follower, beacon detector, and robotic arm to carry plastic balls from a pick up point (which is marked by an IR beacon) and carries them to a destination. Both the pick up point and the destination are marked with black tape. A robot in a game like this would score points based on the number of balls it delievered in a fixed period of time. In the case of a tie, the smaller progam (in bytes) wins.
