A child can bring EM4 Educational Motorized Robot Kit to life in one of its four exciting modes: Cricket—who’s a joy on 6 legs, Beast—the  master of bipedal movement, Trailer—the little engine that could move forward thanks to its motorized transmission, and good ole Grandpa-bot—everyone’s favorite bobble-headed gear-driven family member. Each mode is equipped with its own unique form of movement and with a few easy steps, transforming between each mode is a breeze.
