Powerful 12 VDC motors are combined with precisely machined aluminum hardware to provide the power, strength, and beauty demanded by your mid-sized robot.

The mounting block makes securing this kit a breeze; and the included 6 inch (15.3 cm) pneumatic rubber tyres are durable enough to handle a variety of smooth or rugged terrains without hesitation.

The included Position Controllers use a quadrature encoder system to reliably track the position and speed of each wheel and report the data on demand.

They can also be interfaced with HB-25 motor controllers to automatically provide smooth speed ramping and accurate position control. 

This leaves the main processor free to handle more important tasks like reading GPS coordinates, processing sensors, and manoeuvreing complex environments.
