8.1 Opposed Grips
Trigger Grip
Fingers 2, 3 and 4 close around an object followed by the thumb to maintain it
steady. If the close signal is maintained the index finger will then flex, activating a
trigger. When the close signal is released, the index finger will straighten.
Power Grip
A close signal is sent, and all four fingers flex in towards the palm around an object
with the thumb completing the grip by locking over fingers 1 and 2.
8.0 Grip Patterns
Precision Grip (Open & Close)
In precision open the thumb moves to a known resting position and the index finger
comes to meet the tip of the thumb. The rest of the fingers remain extended and
allow the user to get the hand close to an object.
In precision closed, fingers 2, 3 & 4 close first, the thumb moves to the known
resting position and the index finger comes to meet the tip of the thumb. This
grip is designed to offer the user better visibility of the item they are picking up.
