Soft Robots:FinGripper (3D printable project?)
November 12, 2013
Found this video on Dailymotion while watching old episodes of Dr. Who. There are some interesting ideas about the safety jacket for example, but what really got my attention was the bio-mimicry and soft-gripper design (at about 3:50-4:30) I"m not sure I see quite how the internal hinges on the finger are connected-they may be fixed and they may be moving along the walls somehow. It's a fascinating motion to watch. Here's a link to the company's product PDF. It doesn't do much to explain things though.
This animated gif shows a traditional gripper side-by-side with the "fishGrip" closing in on an egg:
(I know which one I'd want making my breakfast.)
I guess this reminds me in some ways of the BasWheel and I'm hoping that one of you guys with a 3d Printer will find this interesting enough to try a version of your own. A PLA/Flex PLA solution might be a possibility here. Watch the video-it may be enough just to print a pair of extruded, multiple-bar capital "A's" and mount them the way a traditional uses its "Fingers."
I'm not a 3dP guy and certainly don't have the SketchUp/Slic3r chops to make something like this, but it doesn't look terribly complex or time consuming. If anyone thinks it's interesting enough to try it, I'd love to see the results. Oddbot-maybe this could be an option for OddJob.
