A car that can be turned into a robot... Just what your child dreamed of. Smartivity Roboformers Rover-Bot 2-in-1 construction toy allows your child to construct two different toys using the same parts - a wind-up rover, and a attacking bot. In the process, your child is introduced to core understanding of STEAM concepts like wind-up mechanism, gears, elasticity, torque, transfer of energy and laws of motion. It is a win-win either way.
