Creating a rotational mount for the XV11 Lidar is fairly simple from a parts perspective, a slip ring, a spindle, a motor, pillow blocks, and an encoder. The software component includes a joint state publisher for ROS and a pd controller for the spindle speed.
Sorry about the ambiguity. I'm procrastinating with the details and build log. I'm just adding an additional rotational joint in order to get 3D scans similar to the Multisense-SL's setup. If you want to try to revive your lidar you could look at adafruits slip rings. It would be a little tough to modify but doable.
sorry, but I do not get the point. Are you going to build your own Lidar ?
I am a owner of a Neato with a broken Lidar; apparently, the splip ring is dead.
