Ant Group's Robbyant Open-Sources LingBot-Touch Tactile Model

Robbyant, a company under Ant Group, announced the open-sourcing of LingBot-Touch on November 10, a tactile foundation model designed to unify touch perception in robotic hands. The model is pretrained on nearly 5,000 hours of real tactile data and encompasses three sensing principles: magnetic, visuotactile, and piezoresistive. LingBot-Touch addresses the issue of incompatible raw signals from tactile sensors, as touch experiences from one sensor rarely transfer to another. It provides each sensor type with its own input tokenizer, enabling the generation of unified tactile tokens that can be utilized by various action models.
