What happened
Ant Lingbo has open-sourced LingBot-Touch, a tactile foundation model that encodes signals from visual, magnetic, and resistive tactile sensors into a shared representation for action models. In reported tests, adding LingBot-Touch raised π0.5's average success rate on six XHand tasks from 48.00% with raw tactile signals to 74.17%, without changing the model's parameters. The article also links the project page, technical report, code, and model weights.
Why it matters
The article compares raw tactile input with LingBot-Touch across robot hands and tasks, showing how a shared tactile representation relates to reported success rates and transfer to an unseen sensor layout.
