Haptic Glove With MR Brakes for Virtual Reality

IEEE/ASME Transactions on Mechatronics, 2009
Haptic gloves open up the world of force feedback by allowing the user to pick up and feel virtual objects in a natural way. In most of the existing gloves, a remote box houses a large number of actuators and sensors. Power to the glove is transmitted via cables.

MR Fluid Brake for Control of Torsional Vibration

SAE Technical Paper Series, 2005
<div class="htmlview paragraph">The use of a magneto-rheological (MR) fluid brake as a semi-active torsional damper has been investigated. The MR fluid brake can be used as a clutch-type mechanism to transmit torque between a rotating shaft and the brake housing. In that fashion, the MR brake can be used as an adaptive friction damper.

Spherical MR-Brake with Nintendo Wii Sensors for Haptics

2010
This research improves the position measurement system of a magnetorheological (MR) spherical brake we recently designed. The brake is a multi-DOF actuator. The initial design had a position measurement system with infrared (IR) sensors. Although the IR sensors gave good results, there were some performance degradations in the brake due to the noise in

Research on circular plate MR fluids brake

Journal of Central South University of Technology, 2007
The mechanical properties of certain magnetorheological(MR) fluids were investigated and design method of the circular plate MR fluids brake was presented theoretically. The equation of torque transmitted by the MR fluids in brake was derived to provide the theoretical foundation in the design of brake.

Effect of disc hardness on MR brake performance

Engineering Failure Analysis, 2017
Abstract The online control of frictional force using MR fluid makes Magneto-Rheological (MR) brake an attractive option to replace the conventional disc brake. However, initial experiments on MR brake showed deterioration in the braking performance with time.

Development of virtual reality bike with cylindrical MR fluid brake

2012 IEEE International Conference on Robotics and Biomimetics (ROBIO), 2012
Cycling is a healthy and moderate aerobic exercise for the elderly and it works well not only to their physical functions but also to their mentalities. In order for the exercise machine that can facilitate the moderate aerobic exercise for users who cannot do real cycling, we have developed the virtual reality bike (VR Bike) with a cylindrical MR ...

Computer Controlled Rotational MR-brake for Wrist Rehabilitation Device

Journal of Intelligent Material Systems and Structures, 2010
This aricle presents a novel, computer controlled, magneto-rheological (MR) brake actuated, muscular rehabilitation, and evaluation device. The first part discusses various MR brake architectures and compares them. Simple analytical formulae are developed for a set of figures of merit, which point out the role played by the various parameters. Based on

Passive Haptic Interface with MR-Brakes for Dental Implant Surgery

Presence: Teleoperators and Virtual Environments, 2011
In this research a passive haptic interface is explored as a surgical aid for dental implant surgery. The placement of a dental implant is critical since positioning mistakes can lead to permanent damage in the nerves controlling the lips, long lasting numbness, and failure of the implant and the crown on it.

Compact MR-brake with serpentine flux path for haptics applications

World Haptics 2009 - Third Joint EuroHaptics conference and Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems, 2009
This research explores a new approach to shape the magnetic flux path in a MR brake. Magnetically conductive and non-conductive elements were stacked to weave the magnetic flux through the rotor and the outer shell of the brake. This approach enabled design of a more compact and powerful MR brake.

Haptic Glove with MR Brakes for Distributed Finger Force Feedback

Presence: Teleoperators and Virtual Environments, 2009
Most existing haptic gloves are complicated user interfaces with remotely located actuators. More compact and simpler haptic gloves would greatly increase our ability to interact with virtual worlds in a more natural way. This research explored the design of a compact force feedback glove using a new finger mechanism and magnetorheological (MR) brakes
