Sensor feedback

Definition

Sensor feedback refers to the information provided by sensors that is used to adjust and control a system's behavior in real-time. This feedback loop is essential for maintaining the desired performance of systems, especially in robotics and motion control, where precise movements and actions are required. By continuously monitoring the environment or system state, sensor feedback enables dynamic adjustments, ensuring that systems can respond effectively to changes and disturbances.
