GOAL: Generating 4D Whole-Body Motion for Hand-Object Grasping [PDF]
Computer Vision and Pattern Recognition, 2021 Generating digital humans that move realistically has many applications and is widely studied, but existing meth-odsfocus on the major limbs of the body, ignoring the hands and head.

Five-Fingered Passive Force Feedback Glove Using a Variable Ratio Lever Mechanism
Actuators, 2021 Force feedback gloves allow users to touch and manipulate virtual objects intuitively. Compared with gloves providing active feedback force, gloves with passive feedback force are promising in terms of safety and low weight, but simulating the variable ...

Birds land reliably on complex surfaces by adapting their foot-surface interactions upon contact
eLife, 2019 Birds land on a wide range of complex surfaces, yet it is unclear how they grasp a perch reliably. Here, we show how Pacific parrotlets exhibit stereotyped leg and wing dynamics regardless of perch diameter and texture, but foot, toe, and claw kinematics

Grasping Weber’s Law in a Virtual Environment: The Effect of Haptic Feedback
Frontiers in Psychology, 2020 Recent findings suggest that the functional separation between vision-for-action and vision-for-perception does not generalize to situations in which virtual objects are used as targets. For instance, unlike actions toward real objects that violate Weber’

Learning robotic motor skills for dynamic grasping, catching, and dexterous in-hand manipulation [PDF]
, 2023 Endowing robots with human-level grasping and manipulation skills is an appealing yet challenging research topic over decades. Towards more extensive functionalities, the robots should interact with the objects and environment in a more robust, efficient

Learning high-DOF reaching-and-grasping via dynamic representation of gripper-object interaction [PDF]
ACM Transactions on Graphics, 2022 We approach the problem of high-DOF reaching-and-grasping via learning joint planning of grasp and motion with deep reinforcement learning. To resolve the sample efficiency issue in learning the high-dimensional and complex control of dexterous grasping,

Learning Grasp Affordance Densities
Paladyn, 2011 We address the issue of learning and representing object grasp affordance models. We model grasp affordances with continuous probability density functions (grasp densities) which link object-relative grasp poses to their success probability.
