EM4 Motorized Education Robot Kit

The EM4 Educational Motorized Robot Kit allows your child to build four unique robot projects.


This kit is designed to boost your child's kit building confidence by offering easy to assemble robot projects. The EM4 robot kit can be easily assembled into one of four fun projects: a six legged Cricket, a two legged Beast, a rolling Trailer and a bobble headed Grandpa-bot. Robots can be transformed into other robots by simply reassembling the parts.

Each robot features its own unique form of motorized movement. One AA battery is required. The EM4 Robot set comes with everything needed to build one of four robots at a time. Each robot measures about 5 inches square.

Recommended for ages 6 and up.
