Sensors

Definition

Sensors are devices that detect and respond to physical stimuli, converting these inputs into signals that can be processed by a robot's control system. They play a critical role in enabling robots to perceive their environment and make informed decisions based on sensory information. By providing data about various conditions, sensors help robots navigate, interact with objects, and perform complex tasks autonomously.
