A cracked smartphone, a forgotten waffle iron, a beat-up skateboard, some old skis — in the world of the ReBotz, old tech and discarded junk are given new life. This squad of four loveable robot pals springs into action from a heap of junkyard parts. Quickly piece together a motorized model of each ReBot from a set of easy-to-assemble parts. Then, switch them on and watch how each robot moves in a unique and wacky way. Collect all four kits and mix up the interchangeable parts to make your own rebooted robotic creations. These science-fiction models provide an opportunity for some real science lessons. Conduct experiments with the different simple machines and mechanisms that make the robots move, including cams, springs, sliders, cranks, motors, wheels, and levers. + New line with four different build-it-yourself robots that each have a unique design and movement + Learn how different mechanisms make the robot models move in fun ways. + Conduct experiments with cams, springs, sliders, cranks, motors, wheels, and levers. + Mix and match the parts from different kits to make your own wacky robotic creations that look like they’re made from recycled parts. + Battery-powered motors Robots ahoy! This crawling robot is cobbled together from two halves of an old pirate ship’s wheel, and scoots along the floor on a repurposed iron and snow ski. + Fast and easy to build + Demonstrates cranks, cams, and motors in action + Powered by an electric motor + Combine the parts from different ReBotz kits to build your own creations.
