The Rubber Wheel & Motor Kit is a quality pack for indoor robots especially for a home care robot platform and comes with a 12V low noise DC motor 146RPM, encoder and rubber wheel 136×24mm (pair).

Motor:
The DC motor is a customized high quality, low noise, high torque output motor with optical encoder built-in. The optical encoder gives 663 pulses per rotation which is able to sense 0.54 degree rotation from the shaft. This resolution meets general PID speed control requirements thus making it a great choice for robotics. The sturdy metal casing, and gears is a good choice for a competition robot or in harsh environments where your robot might get hit by objects or people. This motor is widely used in the mobile robot area and some stationary automation devices. The optical encoder is cased in a plastic top which is easily accesible, and with the included cable you can easily connect it to your device.

Rubber Wheel:
This high quality rubber wheel is formed after testing more than 6 different rubbers on carpet, wood surface, marble surface, glass surface, with proper softness and tire surface design. The dent on the tire plays a good anti-slip effect and provides a firm grasp over the moving surface. This tire has been widely used on HCR mobile robot platforms.

I bought this kit since I wanted to build a more powerful robot. Usually these motors and wheels can be very expensive, but in my opinion this kit is good value for money if you want a relatively large wheel and powerful motor. With the help of the forum I managed to get the motor and the hall encoder connected easily (although I can imagine that beginner programmers will find the descriptions on the forum a bit vague). I have not found an exactly matching mounting bracket, but if you are willing to file and drill a bit the RB-Cyt-111 bracket can be made to fit.
The package is worth it
