Robo Arm

Design and build a robotic arm that can lift a cup off a table.

Robotic arms are cool, useful, and fun to make. In this video, kids design and build controllable mechanical arms and use their "robo" arms to lift objects and to play a series of games. The video shows kids using the engineering design process, applying a variety of science concepts (e.g., levers and tension and compression), and learning how NASA uses robotic arms in many of its missions.
