The hand that ‘sees’ to grasp
New findings advance our understanding of how vision is used to guide the hand during object grasping.
متن کاملHand synergies during reach-to-grasp.
An emerging viewpoint is that the CNS uses synergies to simplify the control of the hand. Previous work has shown that static hand postures for mimed grasps can be described by a few principal components in which the higher order components explained only a small fraction of the variance yet provided meaningful information. Extending that earlier work, this study addressed whether the entire ac...
متن کاملPurkinje cells signal hand shape and grasp force during reach-to-grasp in the monkey.
The cerebellar cortex and nuclei play important roles in the learning, planning, and execution of reach-to-grasp and prehensile movements. However, few studies have investigated the signals carried by cerebellar neurons during reach-to-grasp, particularly signals relating to target object properties, hand shape, and grasp force. In this study, the simple spike discharge of 77 Purkinje cells was...
متن کاملSearching a valid hand configuration to perform a given grasp ⋆
This paper presents a methodology to find a configuration of an anthropomorphic hand that satisfies some desire contact contact constraints on an object. The proposed approach has an on-line procedure, which iteratively looks for the final hand configuration starting from an initial one using the hand Jacobian, and an off-line procedure, which determines a set of initial configurations for the ...
متن کاملGrasp Planning for a Humanoid Hand
We focus on grasp planning for a humanoid multi-fingered hand attached at the tip of a humanoid robot’s arm. The hand has potential possibility to grasp various objects under several situations. Since the multi-fingered hand can use several grasp types such as fingertip grasp, and envelope grasp with taking the advantage of degrees of freedom. We develop grasp planner which selects a feasible g...
