This pair of white plastic wheels from Pololu with 42mm diameter rubber tires have been custom designed to fit our micro metal gearmotors. The treaded tire gives more grip for adventurous robots and the built in teeth on the inner hub allow an optional wheel encoder to provide feedback to a microcontroller. Overview:
These sturdy plastic wheels are sold in pairs and have rubber tires with grip. They have been designed to fit the output shafts of our micro metal gear motors and should be attached by pressing the shaft into the side with the protruding teeth.
To mount the wheel we recommend the use of the extended micro metal gear motor bracket as the wide rubber tire means the normal brackets will not fit.
A quadrature encoder can be added to the wheel and attached to the same extended gear motor bracket.
