Feedback and position sensing

An encoder’s ability to receive and provide feedback improves its ability to convey movement metrics and the precise location of the robot’s tool center point. After every gear train, supplementary rotary encoders are installed to record the precise location of a robot joint, preventing backlash and zero position error while monitoring retroactive forces. As a result, there is a 70–80% improvement in absolute location accuracy. Modular encoders are perfect for problems with hollow shaft sizes and spatial limits specific to many robots since they employ scale drums or tape and independent scanning units.

Multi-axis arrangement

Because robot joints are completely dependent on one another, it is essential to constantly regulate each axis’ movements to ensure accuracy and consistency. No matter how many axes the robot moves on, such control is made possible by the constant feedback that a rotary encoder provides.

Control of acceleration and velocity

Rotating encoders enable high-quality velocity monitoring by tracking the rotation of a robot’s joints. Operators have more precise control over the robot’s motions since they may precisely modify acceleration in real time depending on this feedback. This maximizes productivity, produces a superior final product, and maintains the process accurately and repeatably.

Every year, automation and robotics become more common in more industries. The encoder you choose can elevate your robotics designs to the next level in the ever-changing and increasingly demanding automation market. Be sure to weigh all of your alternatives and learn how to choose wisely.
