Project Difficulties

The difficulties of this solution are as follows:

  • Randomly stacked: Square steel billets are randomly stacked in the deep bin. Due to potential significant variations in point cloud features resulting from changes in target object poses, the 3D vision system should infer the target object poses based on local features and subsequently generate high-quality point clouds.

  • Path Planning: For randomly stacked square steel billets, considering the robot path constraints, collision avoidance, and other factors, the appropriate robot tool and pick points should be selected to ensure the bin clearance rate.

  • Flexible and easy to use: Suitable for picking square steel billets of different specifications. The vision solution needs to be easy to deploy while meeting user requirements for efficiency, cost control, and other factors.
