An encoder is a sensor of mechanical motion that generates digital signals in response to motion. As an electro-mechanical device, an encoder is able to provide motion control system users with information concerning position, velocity and direction. There are two different types of encoders: linear and rotary.
I'm developing a prototype that uses a quadrature encoder to measure it's linear displacement. The encoder is attached to the prototype body and has a wheel in it's shaft. As the prototype moves straight forward the encoder measure the linear distance.
