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. The

generated 2D point cloud data can be used in mapping, localization and

object/environment modeling.

Compared with RPLIDARs in other series, RPLIDAR S2 has a more stable

performance when detecting objects in long distance, objects in white or black

alternatively and objects under direct sunlight, which is ideal for map building in

the outdoor environment within a 30-meter ranging radius. Therefore, it can be

widely applied in many consumer-oriented business scenarios.

The typical scanning frequency of RPLIDAR S2 is 10Hz(600rpm). With the 10Hz

scanning frequency, the sampling rate is 32kHz and the angular resolution is 0.12°.

Due to the improvements in SLAMTEC hardware operating performance and

related algorithm, RPLIDAR S2 works well in all kinds of indoor environment and

outdoor environment with direct sunlight. Meanwhile, before leaving the factory,

every RPLIDAR S2 has passed the strict testing to ensure the laser output power

meet the eye-safety standard of IEC-60825 Class 1.
