AGV obstacle sensors are including ultrasonic, infrared, LiDAR and visual, etc. Each one of them are
difference: Infrared is cheap and cannot detect black object. Ultrasonic can detect glass and the acoustic
wave has poor controllability may cause false alarm. LiDAR has better controllability but may penetrate
glass. Visual cost higher than any other sensors and cannot detect blind areas.
Benewake are specialized in single-point and 3D directional obstacle avoidance for AGV. LiDAR is a
non-contact, based on Time of Flight principle measurement equipment. It will out put the distance of
the nearest objects.
