چکیده

The control of a passive dissipative haptic interface using electromagnetic dry friction clutches as actuators is considered. The performance of the device is currently limited by actuator performance. A dynamic simulation of the system indicates that actuator torque may be better controlled with torque feedback, resulting in improved path-following performance of the haptic interface. Experimental tests are presented which illustrate the validity of the simulation and the feasibility of implementing torque feedback control on the system’s clutches.

Experimental Evaluation of a New Braking System for Use in Passive Haptic Displays

Passive haptic displays have several advantages when compared to active devices. Safety elements associated with active haptic displays may make them undesirable for certain applications. One method of actuation for passive haptic robots is through the use of brakes and clutches. Traditionally, friction brakes have undesirable behavior, such as stiction and delay in response time due to mechani...

Dial-Based Game Interface with Multi-modal Feedback

This paper introduces a dial-based haptic interface for a brickout game. Conventionally brickout games are played through a mouse or a keyboard. However, these input devices cannot provide sufficient intuitive interface to move the game paddle or provide multi-modal feedback for the user. We developed a haptic game device that gives the user haptic feedback during the game as well as visual and...

Haptic Rendering of Planar Rigid-Body Motion using a Redundant Parallel Mechanism

We present a system for rendering planar rigid-body motion by means of a redundant parallel mechanism. The device design, the control architecture and the passive virtual environment simulation are presented. The system is used to compare various virtual walls and friction models proposed for haptic applications. In addition, the reset-integrator dry friction model proposed by Haessig and Fried...

Interacting with Virtual Environments using a Magnetic

A high-performance magnetic levitation haptic interface has been developed to enable the user to interact dynamically with simulated environments by holding a levitated structure and directly feeling its computed force and motion responses. The haptic device consists of a levitated body with six degrees of freedom and motion ranges of 5 mm and 3.5 degrees in all directions. The current device c...
