Get hands-on with physics and engineering by constructing eight awesome walking machines.
This 134-piece kit contains the supplies to build eight complex moving models inspired by nature. Construct a crawling leopard, a hopping kangaroo-bot and a cool fairy shrimp model that wriggles along on swimmerets. You can even create a monkey that uses its arms to climb along a piece of string. Using the 44 page full-color manual to guide you, explore the working of gear chains and linkages - fascinating!
