VEX Optical Shaft Encoder

With the Quadrature Encoder's two output channels you can measure both the position and direction of rotation of a VEX shaft. This will allow you to calculate the speed of the shaft, as well as the distance it has traveled; these are very useful measurements for autonomous programming. You can measure with greater precision than IR or ultrasonic sensors. More Info


A Programming Kit is needed to change the program in the VEX Controller to use the Quadrature Encoder.
