Introduction The RPLIDAR S2 is the next generation low cost 360 degree 2D laser scanner (LIDAR) solution developed by SLAMTEC. It can take up to 32000 samples of laser ranging per second with high rotation speed. And equipped with SLAMTEC patented OPTMAG technology, it breakouts the life limitation of traditional LIDAR system so as to work stably for a long time. The system can perform 2D 360-degree scan within a 30-meter range.

System connection The RPLIDAR S2 consists of a range scanner core and the mechanical powering part which makes the core rotate at a high speed. When it functions normally, the scanner will rotate and scan clockwise. And users can get the range scan data via the communication interface of the RPLIDAR. Communication and Power Interface Range Scanner Core Figure 1-1 RPLIDAR S2 System Composition The RPLIDAR S2 comes with a rotation speed detection and adaptive system.

value and angle value between object and RPLIDAR S2 via communication interface. 𝐝 Figure 1-2 The RPLIDAR S2 Working Schematic When drove by the motor system, the range scanner core will rotate clockwise and perform the 360-degree scan for the current environment. *Note ： The LIDAR scan image is not directly relative to the environment showed here. Illustrative purpose only.

Safety and Scope The RPLIDAR S2 system uses a low power infrared laser as its light source, and drives it by using modulated pulse. The laser emits light in a very short time frame Class I which can ensure its safety to human and pet, and it reaches Class I laser safety standard. Complies with 21 CFR 1040.10 and 1040.11 except for deviations pursuant to Laser Notice No. 50, dated June 24, 2007.

Self-protection and Status Detection To ensure the laser of RPLIDAR always working in the safety range and avoid any other damage caused by device, the RPLIDAR comes with laser power detection and sensor healthy check feature. It will shut down the laser and stop working automatically when any of the following errors has been detected.
