​General Haptics

Furthering  Human-Machine Interfaces

 

General Haptics' NovoGrip consists of a

parallel manipulator and an exoskeleton that is worn

like a glove.  The parallel manipulator, commonly known

as a delta robot, provides a resistive three-dimensional

force on the operator's wrist.  The exoskeleton allows

active finger movment and transmits forces from the

robot's environment to the operator's hand.  Conversely,

the system transmits  hand and wrist  movements in real

time to the robot.

 

 

Novint Falcon

 

NovoGrip's wrist actuation is provided by the Novint Falcon.  Based in New York, Novint specialises in

developing three dimensional touch capabilities for computing applications.

 

The Novint Falcon allows the operator to move their wrist

in a three dimensional workspace, while receiving force

feedback from the end effector of the delta robot. 

 

 

Realistic Force Feedback
 

Two servo motor acuators exert resitive

forces on the operator's thumb and index finger.  Sensors

relay the force and position data back to the system's

microcontroller.

 

 

Enhancing Manipulation Tasks

 

From surgical robotics to remote manipulation, NovoGrip                                                                                                          

improves the quality of robot manipulation performance.  The combination of wrist and finger actuation

allows operators the flexibility of working with robots that require both proximity and force control. 

 

 

CHAI 3D

 

NovoGrip can be used with the CHAI 3D 

software platform.  CHAI 3D is a collection of C++ open

source libraries for computer simualted haptics.  It supports

3-7 degree of freedom haptic devices and allows custom

force feedback devices to connect with its libraries.
