Unitree 4D LiDAR L2

Description

Unitree’s compact 360° 4D LiDAR for Go2 and robotics projects: it outputs 3D position plus 1D intensity (“4D” data, with a 2D mode), for SLAM, navigation and obstacle avoidance. Higher effective point rate, wider vertical field of view and finer range resolution than the L1, with open ROS1/ROS2/Windows SLAM examples from Unitree.
