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.

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.

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

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.

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 ...

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

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.

MR-fluid yield surface determination in disc-type MR rotary brakes

Smart Materials and Structures, 2008
Magneto-rheological (MR) fluids are currently attracting a great deal of attention because of their unique rheological behavior. Many devices have been designed using MR fluids, and of potential interest here are disc-type MR rotary brakes. The plug flow region in MR devices is defined as the region where the fluid is not flowing.

MR Based Brake-by-Wire System With Self-Energizing and Brake Energy Harvesting Capability

Volume 8: 26th Conference on Mechanical Vibration and Noise, 2014
Brake-by-wire system is a more compact, more efficient brake system using electromechanical actuators instead of conventional hydraulic actuators. Magneto-rheological (MR) fluid is widely used in damping control due to its outstanding controllable properties.
