Technical details and manufacturing context for Position Feedback Sensors

Definition
Position feedback sensors are critical components in robotic part handlers that continuously monitor and report the precise position, angle, or displacement of robotic joints, end-effectors, or moving parts. They enable closed-loop control systems to verify commanded positions, detect deviations, and ensure accurate part handling operations.
Working Principle
These sensors detect physical position changes through various technologies (optical, magnetic, capacitive, or resistive) and convert them into electrical signals. Common types include encoders (incremental/absolute), resolvers, potentiometers, and linear variable differential transformers (LVDTs). The sensor output is processed by the robot's control system to compare actual position with target position, enabling precise motion control and error correction.
