Encoders
An encoder is an electromechanical device which generates an electrical signal depending on the position or the displacement of the measured item. In mobile robotics, rotary encoders are used to measure the movement (direction and speed) of each of the wheels of the robot.
This Optical Encoder Pair Kit for Micro Metal Gearmotors is designed for fitting to the rear of Polulu micro metal gearmotors with extended back shafts. You also get two pairs of toothed wheels in different dimensions, so you can choose your resolution.
These quadrature encoders are essential accessories for Wild Thumper robots. They are supplied with their motors, which can also be used separately.
With this pair of Pololu 12 CPR, 2.7–18V magnetic encoders for micro metal gearmotors, you can equip your micro metal gearmotors with quadrature encoders with Hall effect sensors and a magnetic disc. They are designed specifically for Pololu micro metal gearmotors that have an extended back shaft.
Use this pair of magnetic encoders for your Pololu 20D micro metal gearmotors.
The Me Encoder Motor Driver has an embedded TB6612 circuit for controlling the speed and position of two DC motors as precisely as possible.
This pair of magnetic encoders uses a Hall effect sensor for conveying a digital signal to your microcontroller.
