The unique suspension system acts to keep each wheel in contact with the ground to enable maximum traction, even over rough or bumpy terrain.
The Propeller Project board and HB-25 Motor Controllers provide a reliable control system for this all-terrain robotics platform. The Propeller multicore microcontroller enables you to interface to add-on electronics and sensors for added functionality and mobility, all while monitoring them in real time and making accurate navigational decisions. The motor controllers included are capable of handling up to 30 A each, and provide a durable, easy-to-use method of driving the platform.
