Description: The RPLIDAR S1 is the next generation low cost 360 degree 2D laser scanner (LIDAR) solution developed by SLAMTEC. It can take up to 9200 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 40-meter range. The generated 2D point cloud data can be used in mapping, localization andobject/environment modeling. Compared with RPLIDARs in other series, RPLIDAR S1 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 40-meter ranging radius. Therefore, it can be widely applied in many consumer-oriented business scenarios. The typical scanning frequency of RPLIDAR S1 is 10Hz(600rpm), and the frequency can be freely adjusted within the 8-15Hz range according to the specific requirements. With the 10Hz scanning frequency, the sampling rate is 9.2kHz and the angular resolution is 0.391°. Due to the improvements in SLAMTEC hardware operating performance and related algorithm, RPLIDAR S1 works well in all kinds of indoor environment and outdoor environment with direct sunlight. Meanwhile, before leaving the factory, every RPLIDAR S1 has passed the strict testing to ensure the laser output power meet the eye-safety standard of IEC-60825 Class 1.
TOF Ranging Method
RPLIDAR S1 adopts TOF(Time of Flight) ranging technology, which guarantees the ranging resolution not changing with distance. Even within a longer distance, the ranging resolution is still stable and accurate.
40 Meters Range Radius
The ranging radius of RPLIDAR S1 is up to 40 meters, which meets more application requirements in larger scenarios. 
Resistance to Strong Daylight, Outdoor Available
Effectively avoiding the strong daylight interference, RPLIDAR S1 has a stable ranging and high-resolution mapping performance in outdoor environment.
Small Size, Easy Use
The first pocket TOF laser range scanner of SLAMTEC. Ultra-thin design, compact and portable for various application requirements.
Independent Enclosed Cover
RPLIDAR S1 adopts an enclosed cover to protect its interior mechanism from external interference, which provides a stable working environment and meets the industrial application.
Compatible with SLAMTEC Ecosystem
Compatible with existing hardware and software interfaces of all SLAMTEC products.
360° Omnidirectional Scan
The ranging core of RPLIDAR S1 runs clockwise to perform a 360 degree omnidirectional laser range scanning for its surrounding environment.
Stable Service Life
SLAMTEC has integrated the wireless power, optical communication, non-contact energy and signal transmission technology, to completely solve the electrical connection failure and short lifespan problem caused by the physical contact wearing out, so as to prolong the service life of RPLIDAR S1.
Laser Safety Standard
The RPLIDAR S1 adopts the low power infrared laser light as its light source, and drives it by modulated pulse. It reaches Class 1 Laser Safety Standard which can ensure its safety to human eyes.
Application Scenarios
The RPLIDAR can be used in the following application scenarios:
o General robot navigation and localization
o Environment scanning and 3D re-modeling
o Service robot or industrial robot working for long hours
o Home service /cleaning robot navigation and localization
o General simultaneous localization and mapping (SLAM)
o Smart toy’s localization and obstacle avoidance
