We check out Hyundai's HRL exoskeleton, a robotic mobility suit for paraplegics

Hyundai makes some of the largest vehicles in the world – to wit, 185,000-ton ships with 56-foot high engines making power at 84 rpm – but its R&D division has found enough human-factor synergy with autonomous vehicle development that they're now working on robotic exoskeletons. We were recently introduced to two of these devices: the HRL designed to increase mobility and therefore quality of life for paraplegics; and the WEX, designed to assist in repetitive-motion lifting. Both of these machines are powered by replaceable lithium-ion battery packs with a 4-hour run time and 40-minute recharges. The HRL robotic legs are designed for people 64 to 71 inches tall and less than 250 pounds. The aluminum segments are adjustable in centimeter increments over a 10-cm range, and the 22.4-inch width means it would fit in many long-haul aircraft forward seats. With the 4.4-lb battery pack, the HRL weighs about 41 pounds. There are six 50:1 reduction-gear actuators, two pelvic actuators rated at 224 pound-feet of peak torque with 60-degree range of motion, and two hip and knee with 112 lb-ft peak, 180 degrees and twice the rotational speed of the pelvic motors. Twenty sensors control it all with default speed of just under a mile per hour and a top speed of 1.5 mph, and step length can be adjusted by smartphone via Bluetooth. One of the accompanying crutches has four thumb buttons much like a video-game controller, though they're experimenting with simpler inputs including a joystick. The crutch communicates with the leg unit over a few feet of distance via Zigbee wireless protocol, with security layers added for both obvious reasons and to ensure two users in the same vicinity won't transmit to the other's unit. An HRL can help you sit, stand, walk or climb and descend stairs; it will also stand on its own, simplifying the process of putting it on. Your correspondent is outside the design height limits so rather than do any impromptu CG research we deferred to colleague Chris Davies of Slashgear for impressions wearing it: "It grips tightly, the support would be comforting, and it delivers good posture. It does take some getting used to – when it first lifts up a leg to move it forward you do feel like you're going to fall over – but once you establish a gait and stop over-thinking it becomes much easier." Indeed, he never fell over and most who tried established a rhythm within a few minutes, if not a 1.5-mph sprint.

Tucson hydrogen fuel cell CUV will allow Hyundai to sell more dirty cars

With the first Hyundai Tucson Fuel Cell Vehicle deliveries happening soon (a bit later than expected), it's time for the Korean automaker to explain why it's offering the H2 CUV here in the states. After all, there are only 10 public hydrogen stations in the US today, according to the DOE, so it can't be to take over the market. According to a Hyundai exec, the reason we are getting the Tucson Fuel Cell is to make up to $130,000 through California's ZEV credit system. "We really don't make any money out of selling the fuel cell vehicles for now" – Byung Ki Ahn According to Wards Auto, the California Air Resources Board (CARB) will give the automaker up to 26 points worth of zero emission vehicle (ZEV) credits for each of the $499/month hydrogen Tucson leased through the 2017 model year. Those credits could be worth up to $130,000 to Hyundai. Byung Ki Ahn, Hyundai's director of the fuel cell group, told Wards Auto that, "We really don't make any money out of selling the fuel cell vehicles for now. ... So just by selling the fuel cell (vehicle) we could get a lot of credit points, which you could sell at a later time if you want, like Tesla does. It could be a good business model." Ahn clarified that Hyundai does not plan to cash in on those credits, but to use them to offset the rest of its vehicle lineup. Other automakers also participate in the ZEV credit system, of course, but if Anh's numbers are correct, then fuel cell vehicles earn more credits than battery electric vehicles do, so if you want to earn a lot of credits, hydrogen is a good way to go. You can find more details over at Wards Auto. *This post has been updated to mention other automakers using the ZEV scheme.

Hyundai plant one of 100 factories shutting down in wake of Beijing pollution scare

Many factories and chemical plants have suspended production in Beijing in an attempt to curb dangerous pollution, according to the South China Morning Post. The air pollution is some of the worst the city has seen in years, with harmful PM2.5 particle rates hovering between 200 and 400 micrograms per cubic meter. That number is down from as high as 886 on Sunday. For contrast, the US Environmental Protection Agency regulations say PM2.5 concentration at any location be no higher than 65 micrograms per cubic meter, with average maximums not to exceed 15 micrograms per cubic meter.
China blames the pollution on vehicle emissions, industrial production and an increase in domestic coal use to heat homes during cold weather. A total of 48 work sites, including construction zones, metal refineries and chemical plants have suspended production, and 41 factories have cut back production as well. That includes Hyundai Motor Beijing, which suspended production on Sunday.
Even so, the area's children's hospitals are receiving up to 10,000 patients per day with respiratory ailments. The city's government says it is in the midst of an eight-year plan to curb pollution and that levels have dropped between 30 and 70 percent over the past 14 years thanks to its actions.
