A Castro is an undriven wheel that is designed to be attached to the bottom of a larger object (the “vehicle”) to enable that object to be moved. Your 2-wheel drive at some point requires a third wheel to lean on, if it is not self-balancing , it can lean on this castor wheel. Perfect for use with 2-wheeled robots that need a third-point of support, this Support Wheel comes attached to a mounting plate and requires 4x screws and 4x nuts for fastening to any robot or project. It can rotate a full 360° on the plate and the sleek metal look suits any robot.
