Ant-backed open-source touch encoder lifts π0.5 robot success from 48% to 70%

- Physical Intelligence's π0.5 jumps from 48% to 70% success on 26 real-world robot tasks with a small touch encoder added.
- The encoder is LingBot-Touch from Robbyant (an embodied AI company under Ant Group), open sourced; the Tiny version has only 5.46M parameters, under 0.2% of the policy it plugs into.
- Charts show consistent gains across Diffusion Policy, T-Rex, π0.5 and LingBot-VLA versus raw touch signals.
