UPenn's TitanArm exoskeleton prototype makes light work of heavy lifting (video)
It's no wonder people are interested in exoskeletons. Not only do they tap into our lust for the technology of science fiction movies, but among other applications, can make a significant impact on the lives of those living with disabilities. While many offer leg support, a team from University of Pennsylvania recently took silver in an engineering competition for its TitanArm prototype, a powered upper-body exoskeleton that, as the picture above shows, allows you to out-rep anyone at the gym. Designed to be lightweight and cheap to produce, the robotic bicep upgrade uses a (mostly) aluminum frame, battery-powered DC motor, cable drive system, racket braking and thumbstick controller for movement, with a BeagleBone board supervising the electronics that pull it all together. The group at UPenn imagines TitanArm could be employed as a lifting aid, but more importantly, in healthcare applications like increasing mobility or physical therapy -- sensors and other data from the exoskeleton could even allow docs to monitor patients remotely. More info on the project can be found at the source link, while a video below shows TitanArm in use and outlines the hardware that makes those heavy hammer curls a cinch.
Ekso Bionics' robotic suit eyes-on (video)
Since last we saw the Ekso Bionics robotic suit, which helps folks with lower-extremity paralysis or weakness to stand up and walk, the $110,000 exoskeleton has been on the market for about a year. About 30 have sold so far, and the company's director of marketing and communications, Allison Sojka, reckons that medical centers have already helped rehabilitate somewhere between 500 and 1,000 patients. By allowing them to stand up and walk, the bionic suit not only helps users overcome issues like bone density loss and neuropathic pain related to their condition, but also to gain reams of confidence -- an oft-overlooked factor in the recovery process. The production model is a polished-looking assemblage of aluminum and judiciously placed titanium and carbon fiber, along with sensors, motors, joints, off-the-shelf DSPs and custom circuitry and software. Two lithium-ion batteries power the device (four are included), each of which will go for three to six hours after charging for an hour or so, allowing continuous use of the suit by facilities. Three walk modes are available, namely FirstStep, which is actuated by a therapist with a button push; a user-controlled mode called ActiveStep; and ProStep, which senses user body cues for movement control. The suit also provides audio feedback to help users achieve ideal positioning and transmits stats and data for further review and reporting. Sojka said that the company will release new variable-assist software option in June that'll let patients contribute from zero to 100 percent of the walking power, with the exoskeleton providing the rest -- though there's no pricing yet for that update.

Cyberdyne's robotic HAL suit marches into Japan hospital trials
While climbing mountains and helping disabled tourists are fine pursuits, Cyberdyne's HAL robot suit has found an even nobler occupation: helping patients rehabilitate from debilitating nerve and muscle illnesses. According to The Asahi Shimbun, ten hospitals in Japan will start the first clinical trials of the lower-body suit version we saw last year, designed expressly for use by health care professionals. It works by detecting weak bio-electrical signals from patients' muscles which drive small motors and power units, and will be tested on 30 adults to see if it can help them re-learn to walk. Cyberdyne's wares will be trialed in European hospitals too -- which would be a lot of good service for a company with such an evil moniker.
Matsushita and Activelink unveil rehabilitating robotic suit
If tossing on a HAL cyborg suit and ascending a mountain seems a bit intimidating to you, Japanese firms Matsushita (producer of Panasonic) and Activelink have partnered with Kobe Gakuin University to develop a robotic jacket that helps rehabilitate paralyzed individuals with slightly less "lofty" goals. The vest, which slips over an individual's upper body and arms (no leg support just yet), allows the person to move their unaffected arm as they please, while it mimics the muscles in the paralyzed area(s) to help the patient recall the feelings of maneuvering that limb. By teaching the person to take over for the motorized "stretching and bending compressors" within the device, the 1.8-pound suit can gradually help someone to regain stimulation in a previously motionless area of their upper body. Activelink reportedly plans to "start testing" the unit at a Hyogo hospital soon, and make it commercially available by March 2009. The only kicker is the price -- at ¥2,000,000 ($17,159), customers best ensure their insurance plan is mighty stout before suiting up in this.
