Proprioceptive Sensing

Definition

Proprioceptive sensing refers to the body's ability to perceive its position and movement in space through internal sensors located in muscles, tendons, and joints. This sensory feedback is crucial for maintaining balance, coordinating movements, and enabling complex locomotion patterns, particularly in legged robots that mimic biological systems. Understanding proprioceptive sensing allows for the design of robots that can adapt to changing environments and navigate effectively.
