New AI method reconstructs object shapes from touch alone

Researchers have developed a novel topology-agnostic estimator capable of reconstructing the full mesh of deformable objects using only sparse touch data and no visual input. This method utilizes a permutation-invariant cross-attention architecture to handle various object types, including ropes, cloths, and soft bodies. The approach significantly reduces reconstruction error compared to traditional geometric completion and Gaussian-process baselines, with performance improving as more touch data becomes available. Furthermore, the system's deep-ensemble uncertainty is leveraged to guide subsequent touches, outperforming random and Gaussian-process active baselines in optimizing touch placement for error reduction.

    Topology-Agnostic Mesh Reconstruction of Deformable Objects from Sparse Touch

    Estimating the full shape of a deformable object is especially challenging when vision is unavailable: in the dark, inside an opaque bag, behind the manipulating hand, or under heavy self-occlusion. Touch is the natural sensor in these settings, but touches are sparse and local. …
