Honda’s Walking Assist with Stride Management: Coming to a Hospital Near You!
If, that is, you’re connected to one of 50 Japanese medical institutions now testing and evaluating a pair of the semi-robotic exoskeletal assistive devices. Honda breaks down the what’s-it-do-and-how as follows:

“The [Walking Assist Device’s] control computer activates motors based on information obtained from hip angle sensors while walking to improve the symmetry of the timing of each leg lifting from the ground and extending forward, and to promote a longer stride for an easier walk.”

Honda’s worked closely with several medical institutions throughout development of the Walking Assist Device, but last week’s announcement of the 100-unit roll-out signals what is effectively their flagship field testing effort; a medical trial to collect feedback and evaluations from professionals and patients, and data from the devices themselves, of course. But it’s much sexier than your average medical trial. Because robots. Obviously.

Each rehabilitation and/or physical therapy-focused recipient medical facility gets one medium- and one large-sized device. Details on the cost and duration of the leases haven’t been disclosed, but we do have the following specs:

If successful, the devices will very likely see wider domestic trials, possibly moving beyond rehabilitation and making their way into the homes of Japan’s rapidly aging population. In addition to recovery, the Walking Assist Device could provide just the boost needed for walking to the grocery store, visiting a friend or family member, a healthy stroll around the shopping center, or, for Japan’s endangered farming population, 50% of whom are within 5-10 years of retirement, another trip out to the field.

Given sufficient demand, and should they be cheap enough to produce, the Walking Assist Devices could perhaps be enlarged for populations a bit more… uhhh, let’s be nice and say “a bit more robust.” Among other developed nations, the U.S. also has a growing population of retirees who’d definitely appreciate the extra spring in their step. But Honda, remember, you’re going to need some bigger springs. Sorry about that. It’s a problem. Sorry.

Honda’s Ongoing Assistive Robotics Commitment – Respect Due:
While Honda began specific work on walking-assist devices in 1999, the devices weren’t widely public until 2009. Differences between the current and early iterations are visible in the main image above: on the right and left are the earlier, bulkier, more metallic devices – the middle image, included in last week’s press release, shows the sleeker, current model (the middle image has actually been out in the wild for at least a year, so one assumes the 50 medium and 50 large devices now shipping are the same, possibly with some under-the-hood upgrades and/or modifications).

Unless you’re of a certain level of robo-dorkiness, you might not know that Honda’s actually been pounding away on bipedal humanoid robotics tech since the mid-1980s. You might be unaware of their proactive efforts toward addressing Japan’s aging population crisis through assistive robotics (Akihabara News coverage). And, you could have missed news that Honda’s pursuing a robotics-in-the-home partnership with Sekisui House (even more Akihabara News coverage!).*

Cars, ATVs, a lawnmower perhaps, maybe a sprinkling of ASIMO – that’s the standard mental image of Honda.

Consider upgrading?

Fujitsu has developed technology which can measure a person’s pulse in real time by analyzing video of their face.

“As blood circulates through the body, the amount of light absorbed by the face varies, depending on how much blood there is in it. The first point about this technology is, it identifies minute changes in light intensity on the face, and converts them to a pulse. Also, it accurately detects people’s movements, to distinguish noise. Consequently, it can make a measurement in as little as five seconds.”

When the user is sitting still, the system continuously detects changes in light intensity on the users face, as shown by the green waveform. The red waveform shows the resulting wave with noise associated with movement removed. Fujitsu has found that that accuracy of the system is within about three beats per minute.

“The main point about this technology is, it can make the measurements naturally. All the person needs to do is be in front of the camera, without operating a device. For example, when you’re working on a computer, you often stop moving for at least five seconds while you’re thinking. We think that, by detecting those moments and measuring your pulse rate, this system could be used to support health management, by recording changes throughout the day.”

“In the case of a security camera, it might be possible to detect suspicious persons, based on the assumption that people about to do something risky have a high pulse rate. However, we don’t think that can be done using this technology alone. We think it might be possible through all-round analysis, by combining this with other technologies.”

“We’d like to release this as a device embedded in our products. Right now, we’re working to bring such products out this year, including smartphones as well as PCs.”

We’ve seen Emotiv’s Epoc headset control cars and trapeze acts, but now a small posse of students at Columbia University is teaching it how to control a robotic arm. The appendage, aptly named ARM for Assistive Robotic Manipulator, was envisioned as a wheelchair attachment to help the disabled. According to the team, the goal was to keep costs in the neighborhood of $5,000 since insurance outfits Medicare and Medicaid won’t foot a bill for assistive tech that’s much more than $10,000. To keep costs low, the crew built the limb from laser cut wood, and managed to keep the final price tag at $3,200. Since picking up EEG signals and interpreting them accurately can be tricky, the group says it settled on monitoring EMG waves, which are triggered by muscle movements, for additional reliability.

Lifting your eyebrows makes the device open its grip, clenching your teeth shuts it and moving your lips to the left and right twists the claw, while other motions are currently handled by using a PlayStation 2 controller. In the lab, the contraption has seven degrees of freedom, but it was reduced to five when we took it for a spin. It was hit or miss when this editor put the headgear on, between making sure facial gestures were spot on and the equipment’s attempts to pick up clear signals.

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.

Okay, so what’s an assistive robot?
Well, they’re a lot more cool and useful and tech than it might sound. Think of them more like… social robots, or maybe cybernetic enhancements, or, some years down the road, but not too many, complete physical entities capable of semi-autonomously moving about and taking action in everyday life on behalf of their owner.
As tools, assistive robots passively or actively bridge the gap between what we might refer to as “normal” everyday …
