Re: 3,4 or 5 needed?

GTOlover, mimic doesn't mean "reproduce exactly," at least not in robotics. I was a little surprised that a pinky--i.e., a short final finger--didn't make the grade, but only a little. One of the main goals to be traded off in most of these projects was cost, so five digits weren't usually necessary. You don't need a pinky--as per definition given above--to throw a football, although a fifth finger is helpful. To throw it like a pro player? Yeah, it's probably needed. But that's not what these bots are built for. Plus, the functioning of only four fingers can be vastly improved over the human grasping system, as mentioned in a few of the slide captions.

Given that the post is "Robotic Hands Mimic Humans" and humans have pinkies, it would be good to include this appendage. I am not sure you would call the pinkie useless as it adds an additional control, like throwing a football. Yes it can be done without a pinky, but is it as precise?

Seems a lot of good designs already exist in nature and we just need to copy them to mimic them.

Nadine, I also found that question interesting--how many fingers and what types? I didn't see any discussions of pinkies--I suspect they're unnecessary. I did, of course, see a lot about thumbs.

Thanks, Al. I was surprised at how much work had been done, and how much progress had been made.

Where fluidity of movement is concerned Scotland has already developed such a robotic prosthetic. It is surprising that it has not been included in this slideshow since it is the most advanced of all.

Isn't that true, Chuck? Making robotic movements fluid is still something that engineers need to work on. I saw this recent story that was quite interesting...about a robotic arm that creates delicate art: http://www.fastcodesign.com/1671977/watch-delicate-art-made-with-a-massive-robotic-arm#1

 

Great slideshow, Ann!

Very impressive advances. Did some work many yers ago at the robotics lab at URI. Loved it.

 

Would like to ask if someone knows of an ACTIVE-X comtrol that mimics movements of left or right hand.

Please post a link or info.

Thank you.

Last week, I visited Worcester Polytechnic Institute's robotics department. WPI was the firs university in the nation to offer a BS degree in robotics. See my first of two reports in Students Design Robots.

This report looks at the over all program. Tomorrow's will look at a specific project.

I'm especially impressed with the advances in tactile feedback on new designs.  Manipulating delicate objects is an added feat.

Great slideshow, Ann. I like the Shadow Roboto Dextrous Hand. Making a robot that can accomplish tasks gently is an art.
