Force Discrimination of Finger Pads Using Improved Hand Haptic Interface

A Multi Finger Haptic Hand with Force Feedback

This paper presents a proposal for a twelve degrees of freedom robotic hand system controlled via haptic technology with force control and force feedback. This robotic hand can be used in hazardous environment, deserted places, or aerospace. To achieve this goal, an experimental set up in addition to a computer simulation of this robotic hand system have been carefully designed and built. The e...

Design of a Multi-finger Haptic Interface

In this paper the design of a multi-finger force-reflecting haptic interface device for teleoperational grasping is introduced. The haptic interface or “master” controller device is worn on the human operator’s hand and measured human finger positions are used to control the finger positions of a remote grasping manipulator or “slave” device. The slave may be a physical robotic grasping manipul...

Design of Cylindrical Whole-Hand Haptic Interface Using Electrocutaneous Display

Precise manual work is frequently required in remote and virtual environments. Cutaneous feedback to the whole hand is a key element in achieving this goal; however, most haptic I/O systems for the hand only present haptic sensations to the tips of the fingers. I propose to use an electrocutaneous display to construct a whole-hand cutaneous feedback system. The display shape is cylindrical, to ...

Manual discrimination of force using active finger motion.

In these experiments, two plates were grasped between the thumb and forefinger and squeezed together along a linear track. An electromechanical system presented a constant resistance force during the squeeze up to a predetermined location on the track, whereupon the force effectively went to infinity (simulating a wall) or to zero (simulating a cliff). The task of the subject was to discriminat...
