Sensor

Definition

A sensor is a device that detects and responds to physical stimuli from the environment, such as light, temperature, motion, or pressure. In robotic systems, sensors play a crucial role by providing the necessary data for decision-making and enabling robots to interact with their surroundings effectively. They are essential components that allow robots to perceive their environment, facilitating tasks like navigation, object recognition, and environmental monitoring.
