Build a clever robotic crab that can roam across a tabletop without tumbling over the edge. Once assembled, the robot detects ledges and changes direction automatically, demonstrating how simple mechanical systems can respond to their surroundings. Building and experimenting with the robot seamlessly introduces robotics, motors, gears, mechanics, and sensor-based movement while strengthening problem-solving, logical thinking, fine motor skills, and scientific curiosity. Requires 1 AA battery and a small crosshead screwdriver, which are not included.
