This kit gives you the structural pieces you need to build your own 3pi+ robot. The chassis includes an integrated ball caster and battery holder for four AAA cells, a pair of 32×7 mm wheels with silicone tires, a bumper skirt, and motor clips that can be used to hold in the gear motors for operation without the bumper skirt. The chassis is designed to work with our Micro Metal Gearmotors, and you can add a 3pi+ 32U4 Control Board or your own electronics to complete your robot. Motors and electronics are not included.
