Sensor Feedback

Definition

Sensor feedback refers to the data and information collected by sensors that monitor a robot's environment and internal state, allowing the system to make informed decisions based on that information. This feedback loop is crucial for the robot's ability to react to changes in its surroundings, adjust its actions accordingly, and improve its overall performance. By continuously processing sensor data, robots can enhance their navigation, manipulation, and interaction with objects and environments.
