ME-Dex 1.0: Bringing Heterogeneous Tactile Sensing into World Action Modeling

arXiv · AI, language, vision and robotics · article · Sep 18, 2026 · UTC

World Action Models bring the predictive capabilities of video models into robot action generation, providing a rich foundation for modeling future visual states. Tactile sensing complements this foundation with direct measurements of physical interaction. Some existing methods use tactile features as conditioning inputs without jointly predicting future tactile states, visual observations, and actions. Our key insight is that tactile signals, like video, provide observations of the evolving world state and should be modeled as future observations alongside video. We present ME-Dex-1.0 (MachEm
