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.
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.
Inhabitat’s Week in Green: the world’s tallest skyscraper, mind-controlled robot exoskeleton and a Lego Bat Cave
At Inhabitat, we always keep our ear to the ground for new green structure techniques and technologies as we seek more sustainable methods to shape our world. For the past year, we have actually been following the tale of the Chinese developer BSB, who is planning to create the world’s tallest skyscraper– the completely prefabricated 220-story building is set to break ground next month, and the building is anticipated to take just 210 days to develop. In Chicago, transportation representatives held a formal groundbreaking ceremony last week for the “greenest street in America,” a 2-mile stretch of roadway that is paved with permeable, smog-eating pavement.

Made to help disabled individuals with underdeveloped muscles in their arms, the Wilmington Robotic Exoskeleton (WREX) attaches to the body and makes use of a set of resistance bands and metal bars to offer synthetic strength. Formerly just accessible as an accessory for wheelchairs, 3D printing modern technology has actually made it feasible to create a light-weight variation making use of a plastic backplate, enabling users with healthy legs to stand up and walk around.
The video presentation below shows the WREX being utilized by Emma, a youngster suffering from an unusual congenital illness known as anthrogryposis. Rapid prototyping enables the WREX to scale as she grows, with each individual part being resizable and reprintable. Emma is just one of 15 kids currently using the WREX, and has …

The original Hybrid Assistive Limb (HAL) suit was designed to help those with muscle diseases, but it’s now been upgraded to cope with a very different type of problem: handling radioactive substances. One of the few wearable materials that can stop radiation is tungsten, which is extremely heavy: a typical tungsten vest weigh up to 132 pounds. When worn in conjunction with a HAL exoskeleton, however, a vest can be worn for lengthy periods without causing fatigue — potentially allowing greater access to hazardous sites like Fukushima.

We see interesting exoskeletal mechanisms here on CrunchGear every once in a while, though most of them are pretty specific in their applications. The x-Ar from Equipois is no different: it’s not for making you into a superhuman, but just making people whose work involves constant extension of the arm and heavy lifting be a little less fatiguing.
I mean, think about it: your arm weighs quite a bit, though it’s not something you notice until you have to keep it extended for more than a couple minutes. Imagine if your job involved having your arms out with heavy tools in them for most of the day. My hands get tired just sitting there. The x-Ar is intended to make your arm and whatever you’re carrying feel like they have zero weight. It attaches to your wrist via a cuff and by using technology inspired by steadicams, lets you move freely while still supporting lots of weight.
Equipois’ previous robo-arm let you mount a heavy tool to the end, so this would be more for tasks where the delicacy of a human hand is still required. Sounds good to me. Now if only they’d release one that types for me.
Motorola Xoom rooted in two hours flat, sinister transforming exoskeleton jetpack returns in Verizon ad
What’s the first thing you’re going to do with your Motorola Xoom? If you’re Koush, the answer’s clear — install your very own ClockworkMod recovery image and ROM Manager, and grant the latter superuser permissions. That’s right, on the very day of release, the Motorola Xoom’s all but ready for custom builds of Android and all the joy they bring.
Meanwhile, Verizon’s decided to bring us the latter half of the abruptly cut Xoom TV ad, which actually differs significantly depending on whether or not Spanish is your primary language. Either way, it’s a fairly sordid affair, with no Iron Man feats of stratospheric skill to be found, merely a quick demonstration of gaming with the accelerometer and a few quick swipes through Honeycomb. You’ll still watch it if we tell you it’s after the break though, won’t you?

The so-called HAL-5 is probably the most advanced of the robotic suits designed to help elderly or disabled people walk out there. Made by Japan-based Cyberdyne, it enables handicapped people to walk around and lift heavy objects almost effortlessly – by thought alone.
I’ve seen the spectacular exoskeleton in action several times in Japan, but never got around to wear one. But tech journalist Evan Ackerman did (during the recent CES), as the first American ever.
The way HAL-5 works is that it transforms brain signals sensed through the skin into motion (Ackerman had a sensor on each thigh plus two on his waist). HAL-5′s battery pack lasts for over 2.5h on a single charge.
In the video below, you can see Ackerman wearing HAL-5′s legs, which weigh 15kg in total and support their own weight (the full suit with arms weighs 8kg more). It looks like he’s pretty impressed, and he doesn’t seem to have problems walking (I previously heard of “serious” users in Japanese hospitals complaining about HAL-5 steep learning curve).
