Abstract

Grasping and manipulating objects is an important human skill. Since most objects are designed to be manipulated by human hands, anthropomorphic hands can enable richer human-robot interaction. Desirable grasps are not only stable, but also functional: they enable post-grasp actions with the object. However, functional grasp synthesis for high degree-of-freedom anthropomorphic hands from object shape alone is challenging. We present ContactGrasp, a framework for functional grasp synthesis from object shape and contact on the object surface. Contact can be manually specified or obtained through demonstrations. Our contact representation is object-centric and allows functional grasp synthesis even for hand models different than the one used for demonstration. Using a dataset of contact demonstrations from humans grasping diverse household objects, we synthesize functional grasps for three hand models and two functional intents.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The contact forces that separate stable grasps from infeasible poses are not recorded in kinematic data.

    “the contact forces that distinguish stable grasps from infeasible poses (Brahmbhatt et al., 2019) are unrecorded”

    From Dexterous Robot Manipulation from Human Demonstrations via Contact-Anchored Retargeting and Residual Policy Learning (2026) · cites this paper as Brahmbhatt et al., 2019

    The Introduction (page unavailable) says recorded hand poses lack a clear objective for reproducing demonstrated contact, and the Results (page unavailable) distinguish stable grasps from functional ones. Neither passage says that kinematic data omit contact forces or that those forces distinguish stable grasps from infeasible poses. A search for force-related passages found no statement establishing that claim. (LLM, conf=0.72)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
