The autonomous 3D reconstruction robot is a wheeled-legged robot mounted with MetaCam. Empowered by outstanding obstacle avoidance/surmounting capability and a working time of 60 mins, auto scanning over a site of 10,000㎡ can be achieved. The worker only needs to simply set the task, and the rest of the traversal scanning work can be done by the robot, making the daily scanning work efficient and easy.
