CyberGrasp™ |
|
Groundbreaking haptic interface for the entire hand
|
CyberGrasp™ is an innovative force feedback system for your
fingers and hand. It lets you “reach into your computer” and grasp
computer-generated or tele-manipulated objects.
The CyberGrasp is a lightweight, force-reflecting exoskeleton that
fits over a CyberGlove® and adds resistive force feedback to each
finger. With the CyberGrasp force feedback system, users are able
to feel the size and shape of computer-generated 3D objects in a
simulated “virtual world.”
|
 Grasp
forces are produced by a network of tendons routed to the
fingertips via the exoskeleton. There are five actuators, one for
each finger, which can be individually programmed to prevent the
user’s fingers from penetrating or crushing a virtual solid object.
The high-bandwidth actuators are located in a small actuator
module, which can be placed on the desktop. Additionally, since
CyberGrasp does not provide grounded forces, the actuator module
can also be worn in a GraspPack™ backpack for portable operation,
dramatically increasing the effective workspace. |
 The
device exerts grasp forces that are roughly perpendicular to the
fingertips throughout the range of motion, and forces can be
specified individually. The CyberGrasp system allows full
range-of-motion of the hand and does not obstruct the wearer's
movements. The device is fully adjustable and designed to fit a
wide variety of hands. |
|
Originally developed under
STTR contract to the United States Navy
for use in telerobotic applications, the CyberGrasp system allows
an operator to control a remotely-located robotic "hand" and
literally "feel" the object being manipulated. |
|
Applications |
|
The CyberGrasp system offers enormous benefits for "real world"
applications, including medical applications, virtual reality
training and simulation, computer-aided design (CAD), and the
remote handling of hazardous materials. |

|
Accessories |
|
The GraspPack™ permits mobile force-feedback capability while
wearing the CyberGrasp. The GraspPack is ideal for simulation
applications requiring extended range of motion in a large work
space, such as virtual automobile and aircraft maintenance, and
virtual factory work cells. |
