3 Applications Of Rotary Encoders In Robotics

Robots used in an industrial setting are known for their speed and power. However, accuracy is a point of contention in many cases. Finding the right tools to accurately position and propel industrial automation can be challenging. The main problem arises in the fact that each robot has multiple axes of motion, with each axis requiring its own servo motor. Therefore, manufacturers have to contend with position errors and backlash in each motor. Fortunately, rotary encoders can be employed to solve this problem in robotics. Here are 3 features or applications of rotary encoders that have transformed the landscape of industrial automation.

Uses Of Rotary Encoders In Robotics

Position Sensing And Providing Feedback

Rotary encoders are excellent at processing and communicating feedback. This means it can accurately pinpoint the movement and position of the tool in the robot. However, they can be susceptible to strong vibration and electromagnetic interference. Therefore, only high-quality rotary encoders should be used for this application.

Better Velocity And Acceleration Control

Another major application of rotary encoders lies in monitoring the velocity of the robot during movement, especially the joints. It does this by primarily monitoring the rotation of the joint. This high-quality monitoring helps the technicians to calibrate the acceleration of the joints in real time. This, in turn, leads to more concise movements and improves the efficiency of the whole operation.

Multi-Axis Coordination

Due to multi-axis motion, the robot joints are interdependent on the movement of other joints. Therefore, in order to prevent any errors that might hinder the robot’s precision and control, rotary encoders are employed to carefully monitor the movement of the joint on each axis. 

Thus, rotary encoders are an integral part of industrial automation, particularly robotics.
