Overview
YDLIDAR 4ROS is a TOF (time-of-flight) LiDAR sensor designed for 360° scanning, ranging, and mapping in both indoor and outdoor environments. It features anti-glare capability up to 100KLux, an IP65 enclosed protective cover (waterproof and dustproof), and an integrated motor driver with speed regulation. ROS1/ROS2 support is provided with an open-source package, making it suitable for robot navigation and SLAM workflows on platforms such as Raspberry Pi and Jetson.
