measurement units using gyroscopes and accelerometers help measure the movement and determine the range between reference positions. ■ Image sensors like three- dimensional (3D) cameras and 3D LiDAR are used to identify
integrate information from external sensors into the AMR's sensor fusion system for improved performance. ■ Proximity sensors like laser scanners and two-dimensional (2D) LiDAR detect and track objects near the AMR, including people's movement. 2D LiDAR, 3D LiDAR, and ultrasonics 2D and 3D LiDAR and ultrasonics are common sensor technologies that support SLAM and safety in
AMRs. The differences between those technologies enable one sensor to compensate for the weaknesses of the others to improve performance and reliability. 2D LiDAR uses a single plane of laser illumination to identify
objects based on X and Y coordinates. 3D LiDAR uses
and track nearby objects. ■ Communications links, compute processors, and
multiple laser beams to create a highly detailed 3D representation of the surroundings called a point cloud. Both types of LiDAR are relatively immune to ambient light conditions but require that objects to be detected have a minimum
logistics sensors like barcode scanners and radio frequency identification (RFID) devices link the AMR to facility-wide management systems and
