Slideshow: Robotic Hands Mimic Humans
3/22/2013

Image 1 of 11      Next >

Based on the DLR Hand II, the German Aerospace Center (DLR) and the Harbin Institute of Technology (HIT) jointly developed the DLR/HIT Hand II as a medium-cost multisensory robotic hand. The DLR/HIT Hand II has five fingers, each with three actuators, that are identical except that one of them has an additional drive to make it work as an opposing thumb. To fully emulate human fingers' motor functions, each finger has four joints, not three, and each joint has force and position sensors. The  DLR/HIT Hand II has a total of 15 degrees of freedom (DOF), compared to 13 in the original DLR Hand II. Fingers are equipped with slip-resistant gripper surfaces. Integration of drives and electronics within the hand itself is intended to make it easier to mount on a wide variety of robot arms.

Ann, Great slideshow.  What an impressive group of robotic solutions with the singular focus on robotic hands. It's amazing the amount of research and effort going into this area.

“It's amazing the amount of research and effort going into this area.” @apresher: Exactly some amazing robotic stuff. I fear that the world might not need humans to do work hereafter. A plus as well as a risk that might hit the world if it not being used properly.

3,4 or 5 needed?

I agree, this is a cool slide show.  And, there have been great advances in dexterity in robotic hands.

I'm curious about research into the number of fingers that are really needed and how the assigned task determines that need. Does a robot need a pinky?

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

Tactile Feedback

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

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.

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.

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!

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.

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

Stanford University researchers have found a way to realize what’s been called the “Holy Grail” of battery-design research -- designing a pure lithium anode for lithium-based batteries. The design has great potential to provide unprecedented efficiency and performance in lithium-based batteries that could substantially drive down the cost of electric vehicles and solve the charging problems associated with smartphones.

Robots in films during the 2000s hit the big time; no longer are they the sidekicks of nerdy character actors. Robots we see on the big screen in recent years include Nicole Kidman, Arnold Schwarzenegger, and Eddie Murphy. Top star of the era, Will Smith, takes a spin as a robot investigator in I, Robot. Robots (or androids or cyborgs) are fully mainstream in the 2000s.
