Activelink Power Loader gives HAL some competition, but who’s going to Fukushima?
New Japanese exoskeleton pushing into HAL’s (potential) marketshare
We of the robot/technology nerd demo are well aware of the non-ironically, ironically named HAL (Hybrid Assistive Limb) exoskeletal suit developed by Professor Yoshiyuki Sankai’s also totally not meta-ironically named Cyberdyne, Inc. Since its 2004 founding in Tsukuba City, just north of the Tokyo metro area, Cyberdyne has developed and iteratively refined the force-amplifying exoskeletal suit, and through the HAL FIT venture, they’ve also created a legs-only force resistance rehabilitation & training platform.
Joining HAL and a few similar projects here in Japan (notably Toyota’s & Honda’s) is Kansai based & Panasonic-owned Activelink’s new Power Loader Light (PLL). Activelink has developed various human force amplification systems since 2003, and this latest version of the Loader looks a lot less like its big brother the walking forklift, and a lot more like the bottom half & power pack of a HAL suit. Activelink intends to connect an upper body unit, and if successful, will become HAL’s only real competition here in Japan.
And for what?
Well, along with general human force amplification and/or rehab, this:
Fukushima Cleanup & Recovery: Heavy with High-Rads
As with Cyberdyne’s latest radiation shielded self-cooling HAL suit (the metallic gray model), Activelink’s PLL was ramped up after the 2011 Tohoku earthquake, tsunami, and resulting disaster at the Fukushima Daiichi Power Plant. Cleanup at the disaster area and responding to future incidents will of course require humans in heavy radiation suits with heavy tools possibly among heavy debris. While specific details on both exoskeletons’ recent upgrades and deployment timeline and/or capability are sparse, clearly the HAL suit and the PLL are conceptually ideal for the job. One assumes both will incorporate something like 20-30KG/45-65lbs. per limb of force amplification along with fully supporting the weight of the suit itself, and like HAL, PLL will have to work in a measure of radiological shielding and design consideration. So for now, HAL is clearly in the lead here.
Exoskeleton Competition Motivation Situation
Now, the HAL suit is widely known, widely deployed, and far and away the most successful of its kind ever made. No one else in Japan – in the world – is actually manufacturing and distributing powered exoskeletons at comparable scale. And that’s awesome and all due props to Professor Sankai and his team, but in taking stock of the HAL project’s 8 years of ongoing development, objectively one doesn’t see a whole lot of fundamental advancement. Sure, lifting capacity has increased incrementally and the size of the power source & overall bulk have decreased a bit. And yeah, no one else is doing what Cyberdyne’s doing, but that just might be the very reason why HAL seems to be treading water – and until recently, e.g., Activelink’s PLL, no one’s come along to offer up any kind of alternative.
Digressively Analogizing HAL with Japan & Vice-Versa Maybe
What follows is probably anecdotal, but probably right: See, Japanese economic and industrial institutions, while immensely powerful and historically cutting-edge, are also insular, proud – and weirdly – often glacially slow to innovate or embrace new technologies. With a lot of relatively happy workers doing excellent engineering with unmatched quality control and occasional leaps of innovation, Japan’s had a healthy electronics & general tech advantage for a good long time. Okay but now, thorough and integrated globalization has monkeywrenched the J-system, and while the Japanese might be just as good as ever, the world has caught up. For example, Korea’s big two – Samsung & LG – are now selling more TVs globally than all Japanese makers combined. Okay yeah, TVs ain’t robots, but across the board competition has arrived in a big way, and Japan’s tech & electronics industries are faltering and freaking out, and it’s illustrative of a wider socioeconomic issue. Cyberdyne, can you dig the parallel here?
Back to the Robot Stuff: Get on it, HAL/Japan – or Someone Else Will
A laundry list of robot/technology outlets, including Anthrobotic & IEEE, puzzled at how the first robots able to investigate at Fukushima were the American iRobot PackBots & Warriors. It really had to sting that in robot loving, automation saturated, theretofore 30% nuclear-powered Japan, there was no domestically produced device nimble enough and durable enough to investigate the facility without getting a radiation BBQ (the battle-tested PackBots & Warriors – no problem). Soouch?
For now, HAL & Japan lead the exoskeletal pack, but with a quick look at Andra Keay’s survey piece here at Robohub it’s clear that HAL and the PLL are in a crowded and rapidly advancing field. So, if the U.S. or France or Germany or Korea or the Kiwis or whomever are first to produce a nimble, sufficiently powered, appropriately equipped, and ready-for-market & deployment human amplification platform, Japanese energy companies and government agencies and disaster response teams just might add those to cart instead. Without rapid and inspired development and improvement, HAL & Activelink, while perhaps remaining viable for Japan’s aging society industry, will be watching emergency response and cleanup teams at home with their handsome friend Asimo and his pet Aibo, wondering whatever happened to all the awesome, innovative, and world-leading Japanese robots.
It’ll all look so real on a 80-inch Samsung flat-panel HDTV.
