The TWPS consists of a conveyance module, thin film deposition module, and so on. The conveyance module is a key component in the TWPS because it decides both specifications of produced wire and production system performance. The proposed conveyance module combines transportation and rotation units to achieve transportation rotating the wire. This paper proposes a new mechanism to generate transportation performance by a difference in rotation action of the transportation and rotation units. This paper verities the effectiveness of the new mechanism by experiments.

When the fingertip is pressed and slid slightly on a rigid plate, a partial slip, called Incipient slip, occurs on the contact surface. Since the deformation around the center of the contact surface is small, the center of the fingerprint can be detected during the incipient slip. The Group Delay Spectrum (GDS) tracking is utilized to detect the center of the fingerprint. The velocity of the pointer is determined by the changes of the contact area on the basis of the tracked center. An experimental pointing device is developed to examine the operationality of the proposed method. The experimental results show that an operator can operate the pointer with high accuracy.

Surface electromyogram (surface EMG) and pinching force are measured during the pinching motion of human subjects. Experimental results show that subjects feel comfortable pinching a 60 [mm] cylinder. The surface EMGs are lower in the vicinity of 60 [mm]. Furthermore, a tendon-driven robot hand is developed as a sensing hand prototype. The surface EMGs and the motor torque are compared in a pinching experiment using the tendon-driven robot hand. Experimental results show that the tendon-driven robot hand is effective for quantitatively evaluating pinching effort. Simulation of the pinching motion is conducted using a simple finger model. The simulation results show the importance of finger posture and the moment arm in estimating tendon force. Taken together...

Research paper thumbnail of NAIST hand 2: Human-sized anthropomorphic robot hand with detachable mechanism at the wrist

Dexterity of robotic manipulators can be achieved by equipping an anthropomorphic robot hand with multiple fingers. Additionally, in order to manipulate various tools that humans are using in daily life, the size and the exerting force of the robot hand should be similar to that humans are. In this paper, we proposed a human-sized multi-fingered robot hand with detachable mechanism at the wrist. The robot hand can be split at the wrist into the hand part and the actuator part. The fingers are driven by wires and are controlled by actuators embedded in the arm part. The driving force from the arm part is transmitted to the hand part by gear mechanism at the wrist. The developed robot hand has the size of 200[mm](length) × 78[mm](width) × 24.6[mm](thickness) and can exert 10[N] at the fingertip. The performance of the developed robot hand was shown by a motion control experiment.

The experimental results show that the subjective effort human feels is affected by the size of the object he/she pinches, and the subjective effort correlates with the finger length. The simulation results show that the pattern of the tendon forces is similar to that of the EMG activity measured in the experiment, and the positive correlation was observed between the finger length and the object size where the summation of the tendon forces becomes the minimum. These results suggest that the reason why subjective pinching effort is influenced by the finger posture is the difference in the efficiency of the force transmission from the muscles.
