Uni-VLaT reportedly hits 85% success on back-tap walking with touch, versus 0% without

A user sharing the Uni-VLaT paper says its back-tap walking task had 0% success without touch and 85% with it. The robot walks while its back is tapped and stops when the tapping stops, with no visual signal involved. The user also cites a rise in average success across five tasks from 68% to 75% when a prediction objective is added to raw tactile input, and says the approach generalizes across GR00T and π0.5.
