Robotic sensors are devices that allow robots to perceive their environment. They collect data about various conditions, such as distance, temperature, light, and motion. This information helps robots make decisions and perform tasks more effectively, enhancing their ability to interact with the world around them. Common types of robotic sensors include ultrasonic sensors, which measure distance using sound waves, and infrared sensors, which detect heat and motion. These sensors play a crucial role in applications like autonomous vehicles and industrial automation, enabling robots to navigate safely and efficiently in complex settings.
