RoboCub Coding Caterpillar

Children program a route by physically snapping segments together — forward, left, right, pause, sound — then press the head and watch the caterpillar drive the sequence. No screen and no app, which is the point: the program is a thing you can hold and rearrange.

Eight segments are included, extendable to sixteen. Runs on three AA batteries (not included) for roughly eight hours of play.
