Robots are used for a variety of material handling applications including material handling, machine load/unload, palletizing and depalletizing. 

Traditional 2D vision camera has not always been successful guiding the robot to correctly pick up the part due to lighting variation and the lack of depth information. 

ROBO-PAL, hybrid laser sensing system for material handling, etc. overcomes these problems by virtue of its ability to utilize ultrasonic, laser vision and a web cam to facilitate quick, robust and accurate handling.
