RPLIDAR
360° 2D LiDAR Series
Compact 360° laser scanners for robot mapping, localization and obstacle avoidance — five models from 12 m to 40 m range, for indoor and outdoor use.
Description:
SLAMTEC RPLIDAR is a family of 360° 2D laser scanners for robot mapping, localization, navigation and obstacle avoidance. The S3, S2 and C1 use SLAMTEC's direct time-of-flight (DTOF) ranging; the A3 and A2 use laser triangulation. Ranges reach from 12 m (C1) to 40 m (S3), with sample rates up to 32 kHz and angular resolution down to 0.1125°. The S2 is rated IP65, and the S2 and S3 tolerate strong ambient light for outdoor use. All models work with SLAMTEC's SDK and communication protocol. Compare the models in the table below.
12–40 m — Range, by model
32 kHz — Max. sample rate
0.1125° — Angular resolution
360° — Scanning range
KEY FEATURES
RPLIDAR at a glance
Direct time-of-flight ranging
S3, S2 and C1 use SLAMTEC's SL-DTOF ranging for stable measurement on low- and high-reflectivity surfaces.
Indoor and outdoor
S2 and S3 resist up to 80 klux ambient light; the S2 is rated IP65.
One ecosystem
All models work with SLAMTEC's SDK and communication protocol.
TYPICAL APPLICATIONS
