Description

Osprey Hand This is a wrist-powered device. To use this design, the user must have a functional wrist and enough palm to push against the device to force the fingers closed when the wrist is bent. The Osprey was built in Blender based on the low-poly interior and robust components of the original Raptor Hand, but now sports an attractive fairing and a very durable and comfortable low-profile universal-fit bracer. This device is based on the Raptor design and optimized for the use of heavy gauge nylon monofilament (a widely available option is fishing line). The device has excellent Bowden properties. The cables are pulled to provide flexion and pushed to provide an extension. This device requires neither elastics nor springs nor any mechanical extension system.
