Hi Forrest,

have you tried moving the fingers with SMA-actuators?

A NiTi-wire can contract reversible around 5%-8% of its length and two counteracting wires can achieve until 1s per full move (the limit is the cooling of the then passive wire).

So an arrangement of 2x5 NiTi-actuators in the 'arm' with an appropriate switchable water-cooling could drive really small/lightweight fingers with much higer force and dynamic than geared motors ...

Hi Viktor! Sorry I missed this one. I've responded to your repost in the blog link comments. ;-)
