Slideshow: Robotic Hands Mimic Humans
3/22/2013

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.

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?

“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.

During a teardown of the iPad Air and Microsoft Surface Pro 3 at the Medical Design & Manufacturing Show in Schaumburg, Ill., an engineer showed this "inflammatory" video about the dangers of maliciously mishandling lithium-ion batteries.
It's been two years since the Mac Mini's last appearance on iFixit's teardown table, but a newly revised version joins Apple's lineup this week.
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
