Apparently that sexual harassment suit had a big payoff for Aiko: she's getting a hand. The developers of the fembot have created a hand for her botness, with five movable fingers, 15 movable joints, feedback sensitivity, low power consumption and palatable material cost of $1800. Oddly enough, the appropriate testing grounds for such a hand is Aiko's local neighborhood Starbucks, where she apparently regularly is required to grab straws, cups and cardboard sleeves for coffee she can't drink. How cruel. On the bright side, this hand isn't just for Aiko: it can also be attached to an amputee's forearm muscles, allowing for particularly low cost replacement hand -- though we're guessing it's going to need a bit more work before it's ready for mass human consumption.

If you've ever felt the burning desire to give your index finger a little more prominence in your day-to-day computing exercises, here's your chance. A DIY'er has combined an IR-based, homemade tracking system with a piece of software that he's coded which can translate the IR data into 3D navigation. So far, the system can track the movement of two hands using six individual points (we assume one per axis, per hand). Details are scarce on the project right now, but the prospect of manipulating onscreen images or spaces in three dimensions with a cheap and simple solution is definitely enticing. Check the video after the break to see a finger in action.

Gulp, this is not going to end well. That mechanized hand is just a piece of Kogoro Kurata's latest "secret" creation. Just imagine a massive, bus crushing hand fitted to a fully functional, giant mech and you'll understand our concern. Please Kogoro-san, we beg you on behalf of the children: don't finish it!

Remember that creepy robotic hand we saw terrorizing Japan last week? Well now it's on the loose in some conference room picking up eggs, shaking hands, holding a pencil and crushing a cup with its super action Kung Fu Grip. No video of it crushing skulls but we know what's really going on, we know. Its purpose still isn't any clearer (manufacturing-only or also prosthetics?), only that its functionality is meant to exceed that of the human hand. See just one of many videos after the break.

Gulp. Meet the 5-finger, robotic hand. We don't know much about it, and quite honestly, we're resisting our every urge to cower in the darkness of our thumb-sucking fear. The flimsy premise seems to be that robotic hands will one day be required to replace the aging work force since so many manufacturing processes have been designed around the dexterity of the human hand. Still, why the uncanny likeness Japan? How about a nice shade of gunmetal grey?

Joining the arm, eye, ear, and dolphin (saywha?), the latest bionic creation to come from the doors of the Tokyo Institute of Technology boasts some 33-pounds of crushing power, which could make the Power Glove look a bit weak in comparison. Touted as the "world's first electromechanical prosthetic hand with a grip strong enough to crush an empty beverage can," the creation reportedly weighs a hair over 300-grams and features about half the strength found in the average male hand, but it can extend and flex its fingers in around one second, making sure that the wearer is still a formidible opponent in thumb wars. Unlike similar iterations, however, this rendition utilizes a system of pulleyed cables that run through the fingers, and if all goes as planned, eventual wearers will be able to control the machine by flexing other muscles via "myoelectric control technology."

While we've got robotic assistants that give aid to our ankles, arms, upper bodies, muscles, and legs (just to name a few), researchers at the University of California, Irvine are offering up yet another solution to assist stroke victims regain functionality in their hands. Sure, the Cyberhand and modified P5 glove have already been down this road before, but UCI's Hand-Wrist Assisting Robotic Device (cleverly-dubbed HOWARD) is a purely medical device that was constructed to "help people regain strength and normal use of affected hands long after a stroke." Considering that the first three months after a stroke are when the most "spontaneous improvement" occurs, the device is set into a lineup of scheduled therapy sessions which help victims regain motion, feeling, and grasping abilities of their hands. Additionally, HOWARD requires patients to move at least one-tenth of an inch before the assisting kicks in, which purportedly helps them "remember the feeling" of making motions on their own. Currently, 13 participants have been through HOWARD therapy, and all of them saw 10 to 20-percent improvements in various grasping tests, and while we've no idea when these contraptions will sneak into hospital wards, the team is already hard at work developing a smaller sibling with a bit more software options than the existing rendition.

It's no surprise that humans are doing less and less of the dirty work while they simply control robotic creatures that are actually doing the internal repairs, but a UCLA researcher has devised a ridiculously tiny "microhand" to handle even the smallest surgery-related tasks. The hand, which is said to be a "feat of microscale mechanical systems (MEMS)," measures just one millimeter across when closed into a fist, features four "fingers" made of six silicon wafers each, and touts four gas-powered balloons acting as the muscles at the wafers' joints. As you may expect, the gas lines that run to the balloons inflate and deflate the joints, causing the fingers to grasp and release as needed. The primary purpose is to eventually use the technology in new forms of "minimally invasive surgery," and although the microhand is likely years away from practical use, they're already in cahoots with robotic firm to develop a "slightly larger" rendition with an onboard camera for live action video feeds.

While this certainly isn't the first robotic-fingered hand that we've ever seen, we're always in favor of technology improving dexterity. Those smartypants at the National Institute of Advanced Industrial Science and Technology in Japan (aka AIST) have developed a robotic hand about the size of a human adult male's, measuring 18cm (7.08-inches) from fingertip to wrist and 8.4cm (3.3-inches) across the palm. It also has some sort of mechanism designed to "reduce backlash," which apparently means it'll get more precise control over whatever human it's throttling object it's gripping. We still don't know if that means that now these robots can sew their own gloves yet, though.
