STEM Kit Build Alien Robots Build 10 reptilian-looking robot models, 10 unique mechanisms and learn about the physics of levers and articulated mechanisms. The models are powered by a battery-powered motor box. ● An alien robot snake model with rotating arms and articulated tail, an alien insectoid robot that crawls on six legs, an alien raptor model with wings that move up and down, a claw pincer with a scissor mechanism, a bipedal alien robot model. In addition, you can build models of a pumpjack, oscillating device, hopping alien frog robot, reciprocating arm dino robot and rolling alien dragon robot. The pincers, designed with rolling and climbing functions, give the models an extra touch of realism. The 28X motor with switch offers higher torque and faster speed, and can operate in both clockwise and anticlockwise directions. Assembly is quick and easy. Requires 2 AA/LR06 batteries – not included. A step-by-step illustrated instruction manual guides you through model building and experiments. The durable plastic parts can be reconfigured in a variety of ways; build models from the manual or create your own models, learning mechanical physics with simple experiments. The kit contains 138 parts, 10 models, instruction manual. Recommended age: +6 years. Made of plastic, rubber, polystyrene. According to EN71&ASTM regulations.
