چکیده

We show the existence of two and three finger grasps in the presence of arbitrarily small friction for two and three dimensional smooth objects using a simple new technique. No convexity of the objects is assumed. We also prove the existence of finger gaits for rotating a planar object using three and four fingers. Additional results for smooth convex objects are presented which describe two different finger gaits using four fingers.

Acquiring Visual-Motor Models for Precision Manipulation with Robot Hands

Dextrous high degree of freedom (DOF) robotic hands provide versatile motions for fine manipulation of potentially very different objects. However, fine manipulation of an object grasped by a multifinger hand is much more complex than if the object is rigidly attached to a robot arm. Creating an accurate model is difficult if not impossible. We instead propose a combination of two techniques: t...

MasterFinger: Multi-finger Haptic Interface for Collaborative Environments

This paper introduces the MasterFinger developemt and application, a multi-finger haptic interface for virtual object manipulation. This haptic device, with a modular interface, is specially designed to perform collaborative tasks. Each module is in charge of managing the haptic interaction with a finger. The mechanical structure of the module is based on a serial-parallel structure linked to t...

An involuntary stereotypical grasp tendency pervades voluntary dynamic multifinger manipulation.

We used a novel apparatus with three hinged finger pads to characterize collaborative multifinger interactions during dynamic manipulation requiring individuated control of fingertip motions and forces. Subjects placed the thumb, index, and middle fingertips on each hinged finger pad and held it-unsupported-with constant total grasp force while voluntarily oscillating the thumb's pad. This task...

New Control Architecture Based on PXI for a 3-Finger Haptic Device Applied to Virtual Manipulation

To perform advanced manipulation of remote environments such as grasping, more than one finger is required implying higher requirements for the control architecture. This paper presents the design and control of a modular 3finger haptic device that can be used to interact with virtual scenarios or to teleoperate dexterous remote hands. In a modular haptic device, each module allows the interact...

Multifinger interaction between remote users in avatar-mediated telepresence

In avatar-mediated telepresence, remote users find it difficult to engage and maintain contact, such as a handshake, with each other without a haptic device. We address the problem of adjusting an avatar’s pose to promote multifinger contact interaction between remote users. To this end, we first construct a contact point database for nine types of contact interactions between hands through con...
