Build your own renewable energy-powered robot with the 4M Solar Robot Kit! Teach your kids about mechanics by building a real moving robot that runs on solar energy. No batteries are required! All you need to construct your new friend is included in this kit. When completed, watch the robot walk outside on a sunny day powered completely by the sun's UV rays. Once your robot is assembled you can teach it to do simple, everyday tasks. Household recycled materials can be adapted to turn your robot into a dinosaur or monster with its own personality.
