The VEX Protobot Robot Kit serves as the core around which all of our Robot Starter Bundles and Classroom Bundles are based. Bundles offer the best way to buy a complete robot package while saving you money because they combine the required control systems with the Protobot Robot Kit at a discount. When combined with one of our control system options you can create a radio control, programmable autonomous or dual control robot. This kit contains over 300 parts, pieces and detailed assembly instructions in the form of a Quick Start Guide to build the VEX Protobot Robot, the VEX Tumbler Robot, or some creation of your own design!

If you already own a VEX robot control system, the Protobot Robot Kit includes all the structural metal, fasteners, wheels, gears, and motors you'll need to build either the Protobot or Tumbler robot designs.
