AM890 series chips are high-end LiDAR Navigation Solutions, helping robots to enter into the era of "intelligent identification". It is available for a wide range of peripheral interfaces alternatives and also exceptionally supporting 3DToF and line laser modules so that it could implement LiDAR navigation algorithm calculation and robot motion control meanwhile avoiding obstacles. Flexible and smooth motion mode switching allows the robot to effectively cover the to be cleaned area around obstacles. Accurate and all-covered obstacle detection can effectively reduce the collision and stuck failure.
