Price Options

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.


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.

NOTE: Combine the Protobot Robot Kit with your VEX control system or consider one of our discounted Robot Starter Bundles for a complete working robot.
