What is Encoder -
In robotics, an encoder is a sensor that measures physical movement and converts it into electrical signals, such as measuring how much a motor rotates, which is converted into electrical signals, which can then be processed by a robot’s motion control system. It is possible to group encoders in a few ways such as: Incremental vs. Absolute which is to keep track of positions, Rotary vs. Linear for measuring rotational or linear movement Or the system that is used to measure the movement such as magnetic, optical, capacitive and a few more. As an example, (see figure below) an optical encoder works by a light source emitting a tiny amount […] Read More
