This page collects information on various motors available that are suitable for [robots]. Some motors have a [motor encoder] kit available, to perform [odometry]. ! MiniQ Motor Wheel Set RobotShop sell a [MiniQ Motor Wheel Set w/ Encoder|https://www.robotshop.com/en/miniq-motor-wheel-set-encoder.html|https://www.robotshop.com/en/miniq-motor-wheel-set-encoder.html] that includes two micro gear motors, wheels, white plastic hubs, and a [motor encoder] pair — with the encoders integrated into the motor mount — for US$36. They use a 50:1 gear ratio rather than 298:1 (perhaps that's better?). This uses an optical encoder rather than a Hall Effect encoder, using the white teeth of the inner wheel hub for the optical interrupter, 48 pulses per revolution. ---- [{Tag Hardware Motors}]
