Force and touch feedback, or haptics, can play a significant role in the realism of virtual reality surgical simulation. While it is accepted that simulators providing haptic feedback often outperform those that do not, little is known about the degree of haptic fidelity required to achieve simulation objectives. This article evaluates the effect that employing haptic rendering with different d...

This paper presents a novel three-degree-of-freedom (3-DOF) translational parallel manipulator (TPM) by using topological design method of mechanism (PM) based on position and orientation characteristic (POC) equations. The proposed PM is only composed lower-mobility joints actuated prismatic joints, together with the investigations three kinematic issues importance. first aspect pertains to ge...

Mechanical vibrations adversely affect mechanical components, and in the worst case, lead to serious accidents by breaking themselves. To suppress vibrations, various studies have been conducted on vibration isolation, suppression, resistance. In addition, technologies actively rapidly developed recent years, it has reported that can be suppressed with higher performance. However, these mostly ...

The flexure parallel mechanism (FPM) possessing selective actuation (SA) feature can be used as a micromanipulation system. The design of FPMs with the SA characteristic consists of type synthesis of parallel mechanisms possessing the required number of degree of freedom (DOF), geometric arrangement of the structure to obtain the SA and conversion of the kinematic mechanism into the flexure mec...

We report an experimental highdelity system for making psychophysical measurements on human operators performing real, virtual, and real-remote 3D haptic manipulation tasks. Operators interact with task environments through six-degree-of-freedom (6-DOF) Lorentz magnetic levitation haptic devices. This arrangement allows the operator to exert and experience real, virtual, and real-remote forces/...

The Ouija board is a game associated with involuntary motion called ideomotor action. Our goal is to clarify the conditions under which Ouija board motion occurs, comparing visual, force, and vibrotactile cues. In this paper, we demonstrated a newly developed 1-degree of freedom (DoF) Linear Rail Device, which we used to study these ideomotor actions with less friction and inertia.

Ultrasonic motors have been expected as a leader of new actuators since 1980th when they were invented. Author has been conducted research on analysis of characteristics of ultrasonic motors, development of novel ultrasonic motors including multi-degree-of-freedom (DOF) ultrasonic motors, and application of ultrasonic motors for robotic field. In this paper, several results are described.

In this paper we present the optimized design of the 6 degree-of-freedom (DOF) haptic display VISHARD6, which is directed towards modularity, universal applicability, and high force capability. To investigate the performance regarding force, velocity, and acceleration a generic method for output performance analysis of haptic interfaces is proposed. The device is evaluated according to these me...
