The paper introduces VISTA, a workspace-level equivariant visuotactile diffusion policy designed for data-efficient imitation learning in contact-rich manipulation tasks. VISTA transforms visual and tactile inputs into spherical tokens, fuses them through permutation-equivariant spherical fusion, and aligns the fused representation with the end-effector orientation to produce spatially consistent actions. Experiments in simulation and real-world robotics demonstrate that VISTA significantly improves data efficiency compared to strong visuotactile imitation learning baselines.

arXiv:2606. 11743v1 Announce Type: cross Abstract: Vision-language-action (VLA) models provide strong visual, language, and action priors for robot manipulation, but visual observations alone often miss the local contact state required for contact-rich tasks.
DeCAL is a vision‑language‑action model designed for dexterous manipulation that incorporates tactile sensing through adaptive visuo‑tactile fusion and latent co‑imagination. It uses a Mixture‑of‑Transformers architecture with specialized experts for understanding, imagination, and action, enabling efficient information flow and dynamic regulation of tactile inputs. Experiments show DeCAL achieves state‑of‑the‑art performance, with a 71% average success rate and 83.4% progress success rate, and generalizes well to unseen scenarios.

DexTouch-WM is an action‑conditioned world model that learns from scalable human touch to predict future RGB observations and bilateral tactile dynamics for dexterous robot manipulation. By using compatible piezoresistive arrays on both human and robot hands and retargeting human motion into the robot action space, the model can be supervised with human interaction data while keeping a fixed amount of real‑robot supervision. Experiments show that adding up to 100 hours of human interaction improves robot‑domain visual, geometric, and contact prediction, and the model can serve as a surrogate environment for policy evaluation and synthetic trajectory generation.

ProxiDex is a dynamics‑guided proximity policy framework for multi‑finger dexterous manipulation that treats hand‑object proximity as an interaction state. It reconstructs interaction point clouds, converts geometric distances into proximity cues, and learns action‑conditioned proximity dynamics using a coupled forward‑inverse design. The framework adaptively reweights proximity tokens across manipulation phases and employs dynamics‑consistency supervision to stabilize action generation, leading to improved success rates and robustness in both simulation and real‑world experiments.
