Homemade exoskeleton lets a man lift big cinder blocks with ease
Think you need the budget of the military or a megacorporation to make an exoskeleton for heavy lifting? Nope -- all you need is some standard parts and the know-how to put them together. James Hobson (aka The Hacksmith) has finished a homemade robotic suit whose pneumatic cylinders let him curl 171.5 pounds' worth of cinder blocks with relative ease. While it's not the most sophisticated setup, it's only running at half pressure and could potentially double the load with a compressor upgrade. There's a work log at the source link if you're eager to see how this project came to be. With that said, you'll want to be cautious about trying this yourself -- there aren't any leg supports so far, and those blocks aren't exactly harmless. If you're like me, you'll probably feel safer watching Hobson's demo video below.
Eyes-on: University of Pennsylvania's TitanArm exoskeleton (video)
TitanArm already took home silver in a competition for senior projects at the University of Pennsylvania, and now the team behind it is visiting Orlando to compete in the Intel-sponsored Cornell Cup for embedded design. We stopped by the showroom and snagged a few minutes with the crew to take a look at their creation: an 18-pound, untethered, self-powered exoskeleton arm constructed for less than $2,000. To wield the contraption, users attach the cable-driven mechanical appendage to themselves with straps from a military-grade hiking backpack, and guide it with a thumbstick on a nunchuck-like controller. If a load needs to be held in place, the wearer can jab a button on the hand-held control to apply a brake. A Beagle Bone drives the logic for the setup, and it can stream data such as range of motion wirelessly to a computer. As for battery-life, they group says the upper-body suit has previously squeezed out over 24 hours of use without having to recharge.%Gallery-187514%
Tokyo University of Science shows off robotic suit powered by pneumatic artificial muscles (video)
What can one do with a robot suit? Well, it's certainly not limited to just lifting sacks of rice, but that was exactly what we got to do at CEATEC courtesy of Koba Lab from Tokyo University of Science. First seen in 2009, the magic behind this 9kg kit are the pair of pneumatic artificial muscles (aka McKibben artificial muscles) on the back, which are made by industrial equipment manufacturer Kanda Tsushin. When pressurized with air using electrical components from KOA Corporation, the lightweight, loosely-woven PET tubes contract and consequently provide support to the user's back, shoulders and elbows. As such, our arms were able to easily hold two more sacks of rice (making it a total of 50kg) until the demonstrator deflated the muscles. Check out our jolly hands-on video after the break.
Cyberdyne HAL robotic arm hands-on (video)
If the name Cyberdyne doesn't immediately ring a bell, its HAL (Hybrid Assistive Limb) robotic suit sure will. Here at CEATEC, we bumped into these folks who kindly offered to strap us onto their latest prototype arm -- a slightly smaller variant of the one installed on Cyberdyne's current suit. Most of the HAL's main part was strapped to the outer side of our upper arm with velcro, while our wrist was tied to the much smaller extendable piece; both parts were hinged together with a power unit. Additionally, a sensory pad was applied onto our forearm's medial cutaneous nerve (around the elbow area) to pick up our muscular nerve signal -- similarly, Cyberdyne's lower-body exosuit requires two sensors on each leg. Our HAL was energized as soon as we tensed our arm muscles, so lifting up the tray of four 1.5kg water bottles was a piece of cake consistently throughout the demo -- we even managed it with just our pinky (see video above)! And as soon as Cyberdyne's lovely assistant Fumi turned the dial down, our superhuman powers were instantly taken away. We weren't given any dates or specs for this piece of kit, but if all goes well, we may well see a brand new full-body suit at CES 2012 in January, so stay tuned. Oh, and can someone please get Cyberdyne some WD-40? Zach Honig contributed to this report. %Gallery-135642%
Cyberdyne demos lower-body HAL exoskeleton for helping the disabled, not eradicating mankind (video)
Cyberdyne's HAL (Hybrid Assistive limb) robotic suit has been kicking (stumbling?) around for years now, and at this year's Cybernics International Forum, the company demoed a couple of new iterations of the technology. We've seen the heavy-duty version of the technology scale a Swiss peak, but the new demo showcased a lighter and leaner lower-body suit (not unlike Lockheed's HULC system) meant for helping those with muscle diseases remain ambulatory. The differences between the new rig and previously seen full-body exoskeleton -- meant for use by health care professionals and factory workers to aid in heavy lifting -- are less robust servos and a slimmer profile allowing wearers to worry less over their looks and more over living their lives. Peep the bipedal bionics in action after the break.
Kid's Walker fulfills your child's dream of piloting a kickass robot suit (video)
Four years ago Sakakibara Kikai brought us a $300,000 real-life BattleMech, and the company hasn't sat idle since then -- last December, it put the final touches on a significantly smaller exoskeleton designed specifically for children. The Kid's Walker stands just over five feet tall and weighs four hundred pounds, and though the gasoline-powered creature doesn't exactly walk, its wheeled feet definitely stroll around. The Japanese company told Gizmag the suit isn't presently for sale -- just rentals for now -- but would probably cost about 1.8 million yen (around $21,600) should it come to market. If you ask us, that's a small price to pay; everyone knows it's always the young mecha pilots that end up saving the world. Video after the break.
Video: Power Loader has giant freaking robot arms!
We've seen our fair share of useful but ugly and pretty but pointless robotic concoctions, but nothing quite like this. The Power Loader suit, which was directly inspired by the mech outfits in Aliens, is in our humble opinion an exoskeleton done right. With two massive protruding arms, capable of lifting 220 pounds without a sweat, direct force feedback for intuitive control, and even powered legs, we're inclined to believe what we're seeing here is a tiny glimpse of the awesome mech-dominated future we've been waiting so long for. Also known as the Dual-Arm Power Amplification Robot, this is produced by Activelink, a Panasonic subsidiary, and you might be shocked to discover that there are plans afoot to commercialize it by 2015. Entrancing video after the break.
Wearable farming robot suit takes the load off
Hard to believe we're seeing yet another wearable robot suit emerge from Japan, eh? All sarcasm aside, there actually is a newcomer to the curiously growing market courtesy of Shigeki Toyama and colleagues from the Tokyo University of Agriculture and Technology. The aptly dubbed farming robot suit is a strap-on contraption that makes lifting objects much easier than nature intended, reportedly reducing the wear and tear (read: force) placed on one's joints, knees and back by around 50-percent. Additionally, the suit will be programmable depending on the type of work being done, but we've no idea if any third-party attachments (you know, rubber band launchers, integrated HMDs, etc.) are in the works. On the real, you'll be looking at around ¥500,000 ($4,559) to ¥1,000,000 ($9,117) to ease your load, but that could dip as low as ¥200,000 ($1,823) per suit if mass production becomes viable.[Via The Register]
HAL-5 robotic suit ready for mass production
Tsukuba University engineering professor Yoshiyuki Sankai could probably give his two weeks notice if he should so desire, as his brainchild -- better known as HAL -- is getting ready for "mass production." Cyberdyne has embraced the overwhelming potential available in a fully robotic suit, which could prove handy in such applications such as "walking assistance and rehabilitation, nursing, factory work and disaster relief." Having already assisted a paralyzed individual (almost) summit a mountain, the robotic suit will reportedly find itself in hospital wards in Tsukuba city (alongside the HOSPI, presumably) soon, and the company plans to produce "20 units" by 2007, while ramping up to "400-500" in 2008. While the idea of having your own personal strength-boosting Halloween costume might sound appealing, you'll have to pony up an estimated "¥5 million ($42,273) - ¥7 million ($59,182)" to purchase one, or ¥70,000 ($592) per month to rent, but even that's pocket change compared to throwing down for your own personal Land Walker.[Via Engadget Japanese]
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.
