RPLIDAR A1 is a low cost 360-degree 2D laser scanner (LIDAR) solution developed by SLAMTEC. The system can perform a 360degree scan within a 6meter range. The produced 2D point cloud data can be used in mapping, localization, and object/environment modelling.

• Measures distance data in more than 8000 times/s
• 360 Degree Omnidirectional Laser Range Scanning
• 8000 times sample rate, the highest in the current economical LIDAR industry
• OPTMAG Original Design, prolong the life-span
• Configurable Scan Rate from 2-10Hz
• Ideal for Robot Navigation and Localization
• Plug and Play
