Haptic Device with Parallel Mechanism

Design of a New Haptic Device using a Parallel Mechanism with a Gimbal Mechanism

This paper proposes a new haptic device using a parallel mechanism with gimbal type actuators. This device has three legs actuated by 2-DOF gimbal mechanisms, which make the device simple and light by fixing all the actuators to the base. Three extra sensors are placed at passive joints to obtain a unique solution of the forward kinematics problem. The proposed haptic device is developed for an...

SenSation : A New Translational 2 DOF Haptic Device with Parallel Mechanism

We propose a new two -degree of freedom para llel mechanism for a haptic device and will refer to the mechanism as the SenSation. The SenSation is designed in order to improve the kinematic performance and to achieve static balance. We use the pantograph mechanisms in order to change the location of active joints, which leads to transform a direct kinematic singularity into a nonsingularit y. T...

Kinematically Redundant Parallel Haptic Device with Large Workspace Regular Paper

In this paper, a kinematically redundant parallel haptic device with large workspace is presented. The haptic device has a similar kinematic structure to the well‐ known Delta manipulator. However, it has a special arrangement of actuators and one redundant actuator added to the third leg. The proposed haptic device has essentially 4‐DOF, however, only three tra...

Design , Fabrication , and Evaluation of a New Haptic Device Using a Parallel Mechanism

This paper present design, fabrication, and evaluation of a new 6 degree-of-freedom haptic device for interfacing with virtual reality by using a parallel mechanism. The mechanism is composed of three pantograph mechanisms that are driven by ground-fixed servomotors, three spherical joints between the top of the pantograph mechanisms and the connecting bars, and three revolute joints between th...
