Smart sensors allow smart equipment to have a variety of "feel" sensors as the only autonomous input for smart equipment. It is equivalent to various sensory organs of intelligent equipment and robots. The perception of smart laser pointer equipment to the external environment is mainly visual. Position, speed, force, touch, etc. Vision is the most commonly used input system for intelligent equipment, and can be divided into two categories: one is intuitive vision, the data type is a picture composed of pixels, and a typical application is machine vision. Object recognition, etc. Such sensors include high-speed cameras and video cameras. The second is environmental model-based vision. The data type is a spatial model composed of point cloud data. A typical application is spatial modeling. Such sensors include 3D lidar and laser scanners.
Position awareness refers to the perception of the distance between surrounding objects and oneself. In order to determine the location of the environment, such sensors have laser rangefinders. 2D lidar, magnetometer (to determine direction), millimeter wave radar, ultrasonic sensor, etc. Speed perception refers to the knowledge of the speed, acceleration, angular velocity and other information of the intelligent equipment running. Such sensors include speed encoders, acceleration sensors, gyroscopes, etc. Force perception is used in smart equipment to sense the force of external contact objects or internal mechanical mechanisms. Typical applications are force sensors mounted on joint actuators. Used to achieve force feedback. A force sensor installed between the end of the robot arm and the last joint of the robot. Used to detect the force exerted by an object, etc.
