Wearable Robot Adds Two Fingers To Your Hand

rtoz writes: Researchers at MIT have developed a robot that enhances the grasping motion of the human hand. This wrist-wearable robot adds two extra fingers that respond to movements in the wearer's hand. The robotic fingers are on either side of the hand — one outside the thumb, and the other outside the little finger. A control algorithm enables it to move in sync with the wearer's fingers to grasp objects of various shapes and sizes. With the assistance of these extra fingers, the user can grasp objects that are usually too difficult to pick up and manipulate with a single hand.

      They should probably have read their Shirow, instead. To wit, it makes much more sense to add more arms than to do anything else. We already have two arms which are good at doing fine work. Adding more fingers to them will only make them more cumbersome. Instead, you add more arms to perform gross tasks, like holding things up for a long time, carrying or moving heavy things, and so on. These arms could be programmable to continue doing whatever you were doing, whether it be static, dynamic, or include aspects of both. For example, clamping two items together, operating a pump, or holding a camera steady, respectively.

      The GP was imprecise. The Gripping Hand of the Moties in the Niven/Pournelle CoDominium universe is a third arm/hand - it is used for strength and better grip. Two hands for detail/fine work, one for heavy lifting/gripping.

      It's also used in the sense of a "third way" between two sides of an argument - "on the one hand, on the other hand and on the gripping hand". The gripping hand argument is supposed to be the strongest one and a way around the weakness of the core conflict.

      Right. And at least one Shirow suit (but several, IIRC) has big arms above the wearer's normal arms, which can be used to do stuff like throw cars. But the wearer's arms can also be used while the suit is worn, to do fine work that doesn't require massive arms that are themselves around the size of a human in body armor.

    4. Re:Third hand? by danomatika · · Score: 1

      Some context from Stelarc's website:

      The hand was completed in 1980 in Yokohama. It was based on a prototype developed at Waseda University. It was constructed with the assistance of Imasen in Nagoya. It has been used in performances by the artist between 1980- 1998 in Japan, the USA, Europe and Australia. It has become the best- known and longest-used performance object for the artist. Originally it was designed as a semi- permanent attachment to the body, but because of skin irritation from electrode gel and the weight of the hand, support structure and the battery pack (approx. 2 kgms), it could not be worn continuously and thus it became a special performance device. The Third Hand has come to stand for a body of work that explored intimate interface of technology and prosthetic augmentation- not as a replacement but rather as an addition to the body. A prosthesis not as a sign of lack, but rather a symptom of excess. The Third Hand performances, with amplified body signals and sounds, have contributed to cyborg discourses on the body, included in more recent performances such as FRACTAL FLESH, PING BODY and PARASITE. See documentation of the performance postcards for a conceptual context.
