Feature: 1. Long Life: The radar sensor uses a combination of wireless power supply, optical communication, non contact energy and signal transmission technology, which completely solves the problem of electrical connection failure due to physical contact wear and tear and the short life span of the lidar, making the radar last longer. 2. Strong Light Resistant: The radar sensor is strong light resistant and can be used both indoors and outdoors The for RPLIDAR S1 can effectively avoid the interference of ambient light and strong daylight to achieve stable ranging and high accuracy map building in outdoor scenes. 3. Wide Application: The lidar sensor can be used for general purpose simultaneous localisation and mapping (for SLAM), environmental scanning and 3D reconstruction, home care, navigation and localisation of cleaning robots, general purpose robot navigation and localisation, smart toy positioning and obstacle detection. 4. Small and Lightweight: The lidar sensor is small and lightweight, making it easy to install in situations where space is limited. 5. Long Lasting: This lidar sensor is made of ABS and is very reliable, compatible, has a long measuring range and a long service life.
