Grip Patterns & Features
As well as the individual digit control, our robotic hand is pre-programed with 14 standard functional grips modelled after the most common human grip patterns, accessible through our ROS (Robot Operating System) 2, Python ECI API. These grip applications have been thoroughly tested through the prosthetic product line in helping replicate human hand function in day-to-day tasks; then adapted to the robotic hand.
Opposed grips are defined by the thumb being in opposition to the fingers, while non-opposed grips position the thumb parallel with the fingers on the hand.
Grips: Power, Precision Closed, Precision Open, Tripod, Trigger, Glove, Tripod Open, Grab, Finger Point, Tap, Relaxed, Cylinder, Column and Key.
