"Trautman-Style" OPP T-Hooks Delivered; Lego Hand; MMG · 15 April 07 by Jonathan Kuniholm
We’ve completed four more “Trautman-Style” OPP T-Hook prototypes, and donated them to longtime users for evaluation. We’re told that one, a retired welder, had repeatedly repaired his hook himself until, after 15 years of repairs, it was no longer salvageable. A more detailed update is available below.
John Bergmann, a volunteer, has completed a very cool LEGO extrinsically actuated hand. We’ve put a more detailed update in the mechatronic arm project section, where you can download complete instructions for constructing the hand. We’re working on a way to actuate it. Please consider building one and coming up with something.
Jorge Silva, a PhD student at the University of Toronto, has put together some great instructables on our group page explaining how to construct sensors for acoustic myography (MMG), or the measuring of the sounds made by muscles when they contract. The page also has some activity on a couple of other topics.
