Whiskers on Robots
Sometimes sophisticated sensors based on video cameras, infrared or ultrasound are not quite up to the job, and we have to resort to somewhat more primitive switch-type sensors. These work like an animal’s whiskers (or ‘antennae’ on insects), detecting nearby objects in the environment. When disturbed, a sensor sends a pulse to the robot to indicate that an object is present.
