Puck bouncing off rails, sliding fast enough that you flinch, and the arm still gets its blade behind it. Real hardware, not sim, no one on the controls.
The system behind this clip is LingBot-VA 2.0, a from-scratch video-action model out of Robbyant. It's framed as world-model-grounded rather than purely reactive, a different bet than pi-0.5's reactive VLA approach. On the dual-arm RoboTwin 2.0 benchmark it scored 93.6 avg, though that's only a +1.4 gap over its own 1.0 and needs independent reruns to mean much.
One thing to keep straight: the 225 Hz is control step frequency from chunking 142 ms forward and unfolding K=32 low-level steps, not model forward passes. Actual policy throughput is closer to 7 chunks a second. Still real-time, just not 225 Hz inference. Project page link in comments.
