About this product

RoboSense Bpearl is a 32-channel spinning LiDAR for detecting near-field blind spots around mobile robots and autonomous vehicles. Its 360° horizontal coverage and 90° vertical field of view suit installations where a sensor needs to see obstacles close to the vehicle body. RoboSense lists autonomous delivery robots, sweepers, security robots and robotic forklifts among its intended applications.
