LiDAR SLAMTEC RPLIDAR S3 (40M) TOF

Buy the SLAMTEC RPLIDAR S3 lidar for accurate navigation and reliable obstacle avoidance of your robot or drone

SLAMTEC RPLIDAR S3 is a new generation of 2D laser scanners with direct time-of-flight (dToF) technology. The model provides a stable scanning range of up to 40 meters at 70% reflectivity and up to 15 meters for objects with low reflectivity (10%).

With a sampling rate of 32,000 points per second and angular resolution of up to 0.1125°, the lidar generates a detailed point cloud for mapping, navigation and detection of small objects. With a compact body of just 41 mm and a weight of 115 g, the S3 is the smallest lidar in the SLAMTEC range. This makes it easy to integrate into any mobile platform.

• Maximum scanning range up to 40 meters for working in large spaces.
• High measurement rate of 32,000 points per second for detailed mapping.
• 0.1125° angular resolution for small object detection and precise positioning.
• Light protection up to 80,000 lux for stable performance in bright sun and indoors.
• IP65 protection class and compact size for operation in any environment and easy integration.

How RPLIDAR S3 lidar works

The lidar uses SL-TOF technology, SLAMTEC's own development based on direct measurement of the time of flight of a laser pulse. The device emits modulated laser pulses, measures the time of their return from objects and calculates the distance with an accuracy of ±30 mm.

The rotating mechanism provides a full 360° view with a typical scanning frequency of 10 Hz (up to 20 Hz). The built-in processor generates a 2D map of the environment in real time. Data is transmitted via the TTL UART interface at a speed of 1 Mbit/s. Class 1 laser is safe for the eyes. Due to its high resistance to external illumination, the lidar maintains accuracy even in direct sunlight.

Specifications

The RPLIDAR S3 model has a working range from 0.05 to 40 meters for objects with 70% reflectivity and up to 15 meters for objects with 10% reflectivity. The blind zone is only 0.05 meters.
