With the Roboxplorer Kit by SmartLab Toys children can construct their very own multi-terrain robotic vehicle, complete with six S-shaped legs intended to triumph over some of the toughest terrains, such as sand, rocks, and grass. Experiment with its limits by towing toy cars, climbing a stack of books, or negotiating a wall—RoboXplorer will stop at almost nothing! Included with the Roboxplorer Kit by SmartLab are instructions for five guided projects that touch upon the science of motion and energy to explain why RoboXplorer reacts differently to various landscapes. In addition, you receive a science journal, 32 plastic pieces and a gear box. Requires 3 AAA batteries, not included.
