Proprioceptive sensors

Definition

Proprioceptive sensors are specialized sensors that provide information about the position, movement, and orientation of a robot's body parts relative to itself and its environment. They play a crucial role in allowing robotic systems to understand their own physical state, which is essential for effective navigation and manipulation in various tasks. By simulating or implementing these sensors, robots can achieve a level of self-awareness necessary for complex interactions and tasks in both simulated and real-world settings.
