RPLIDAR A1 is a low cost 360 degree 2D laser scanner (LIDAR) solution developed by SLAMTEC. The system can perform 360 degree scan within 12-meter range (6-meter range of A1M8-R4 and the belowing models). The produced 2D point cloud data can be used in mapping, localization and object/environment modeling.
RPLIDAR A1’s scanning frequency reached 5.5 hz when sampling 1450 points each round. And it can be configured up to 10 hz maximum. RPLIDAR A1 is basically a laser triangulation measurement system. It can work excellent in all kinds of indoor environment and outdoor environment without direct sunlight exposure.
RPLIDAR A1 is based on laser triangulation ranging principle and uses high-speed vision acquisition and processing hardware developed by Slamtec. The system measures distance data in more than 8000 times per second.
360 Degree Omnidirectional Laser Range Scanning
The core of RPLIDAR A1 runs clockwise to perform a 360-degree omnidirectional laser range scanning for its surrounding environment and then generate an outline map for the environment.
The sample rate of LIDAR directly decides whether the robot can map quickly and accurately.
RPLIDAR improves the internal optical design and algorithm system to make the sample rate up to 8000 times,

OPTMAG Original Design
Most traditional non-solid LIDARs use slip ring to transfer power and data information, however, they only have thounds of hours of life due to mechanical wearing out. Slamtec has integrated the wireless power and optical communication technology to self-design the OPTMAG technology, which breakouts the life limitation of traditional LIDAR system. It fixes the electrical connecttion failure caused by the physical wearing out so as to prolong the life-span.
Configurable Scan Rate from 2-10Hz
Users can adjust the scan rate by alternating the motor PWM signal
Ideal for Robot Navigation and Localization
RPLIDAR is the designed sensor for applying SLAM algorithm
With the scan rate set as 5.5Hz and the resolution is 0.2% percent of the actual distance
Plug and Play
Just connecting the RPLIDAR and a computer via a micro USB cable, users can use the RPLIDAR without any coding job
Applications
Multi-point Touch and Man-machine Interaction
Compared with traditional technology, with infrared laser device, the RPLIDAR A1 can realize the multi-point touch on a super-large screen, which has a higher resolution, reacts quickly and resists ambient light.
Robot simultaneous localization and mapping (SLAM) Environment scanning and 3D rebuilding
Obstacle detecting and avoiding Multi-point touching and man-mechine interaction
