DLR predictive simulation compensating 6-second round-trip delay

This brief video shows results of the ROTEX experiment on the fully automatic grasping of a small free-floating cube with flattened edges by the ground computers which evaluated the stereo images from the robot gripper, estimated the motion, predicted it for the 6 s communication round-trip delay, and sent up the commands for grasping. In the view are the results of predictive simulation (right-hand side) and the delayed true-camera measurements (left-hand side).
