The fingertips and fingerpads are very important organs in human hand for handling minute objects, for example, picking up, carrying and rolling them. Therefore, imitating the advantages of these organs can lead robot hand to improving dexterity of the finger operations. In this paper, dexterity of pinching and rolling the minute objects is brought by explicit designing of the tip part of fingers...
This paper proposes a segmentation method of human manipulation task based on measurement of contact force imposed by a human hand on a grasped object. We define an index measure for segmenting a human manipulation task into primitives. The indices are calculated from the set of the contact forces measured at all the contact points during a manipulation task. Then, we apply the EM algorithm to the...
Human hands are capable of many dexterous grasping and manipulation tasks. To understand human levels of dexterity and to achieve it with robotic hands, we constructed an anatomically correct testbed (ACT) hand which allows for the investigation of the biomechanical features and neural control strategies of the human hand. This paper focuses on developing control strategies for the index finger motion...
The actual development of humanoid robots has recently led robot designers to take interest in human-like artificial hands to be used by anthropomorphic manipulators instead of the classic, but so weakly anthropomorphic, industrial robot gripper. Controlling a robot upper limb with an artificial hand is, according to us, a new challenge for robotics. We analyze how to derive a Denavit-Hartenberg table...
