Chapter 13: Sensors and Perception: Types of sensors (proximity, tactile, vision, force)
Abstract: When discussing sensors in terms of perception, the main types include: proximity sensors which detect the presence of an object without physical contact, tactile sensors that measure physical contact and force applied, vision sensors (like cameras) that capture visual information, and force sensors which specifically measure the magnitude of applied force . Explanation of each type: Proximity sensors: Use various methods like ultrasonic waves, infrared light, or magnetic fields to determine how close an object is without touching it. Examples: capacitive proximity sensors, photoelectric sensors, inductive sensors. Tactile sensors: Detect direct physical contact with an object, often measuring the pressure or force applied. Can be designed to sense pressure distribution across a surface, providing detailed information about the object's shape and texture. Examples: piezoresistive tactile sensors, piezoelectric tactile senso...
