But as @Tully already wrote in another comment: you will need to give more detailed info on what specific you try to achieve (preferably with a sketch or image), how exactly you are currently trying, and what specific problems you run into that make it not work. | |

The difficulty really lies in making attachments with an entity whose location and ID I cannot know a priori, I would like to emulate the most realistic behavior possible and looking on the net I found only about vacuum gripper (not working) and I was looking for something that would narrow down the check on entities in a particular area of the gripper, and then make attachments with the closest one based on the lidar msg. | |
