Sensors

Definition

Sensors are devices that detect and respond to physical stimuli, such as light, heat, motion, or pressure, converting these inputs into signals that can be processed by a robot. They play a critical role in how robots perceive their environment, allowing them to interact intelligently with the world around them. By gathering data about their surroundings, sensors enable robots to perform tasks more effectively and safely.
