The core of RPLIDAR A2 runs clockwise to perform a 360 degree omnidirectional laser range scanning
for its surrounding environment and then generate an outline map for the environment.
 
Compared with traditional technology, with infrared laser device, the RPLIDAR A2 can realize the multi-point touch on a super-large screen, which has a higher resolution, reacts quickly and resists ambient light.
 
Applications:
Environmental scanning and 3D reconstruction
Robot simultaneous localization and mapping (SLAM)
Obstacle detecting and avoiding
Applications: Multi-touch and human-computer interaction
Multi-point touching and man-machine interaction
