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.

Hyundai's all-new 2018 hydrogen-powered CUV comes into focus

It's no secret that Hyundai has plans for hydrogen-powered vehicles beyond the currently available Tucson Fuel Cell. Ever since the debut of the Intrado concept at the Geneva Motor Show in early 2014, Hyundai has been dropping hints about what the new big-ish H2 vehicle will offer. We say "big-ish" because Hyundai Motor Group's director of eco-vehicle development, Ahn Byung-ki, told Automotive News that the next-gen hydrogen powertrain will find a home in a "totally new" model that will be "somewhere between a CUV and SUV." So, whatever fancy new automotive segment that phrase happens to define – MUV, for middleweight utility vehicle? – is what Hyundai's new hydrogen offering will be. Under the hood, the upcoming vehicle will use a fuel cell that doesn't need as much platinum and will have a bigger battery and a smaller motor. We had originally heard that this new hydrogen CUV/SUV would arrive in 2020, but Ahn said that the 2018 Winter Olympics, which will be held in Pyeongchang, South Korea will be "a big event. That's always a good opportunity for PR." With the Intrado concept, Hyundai said it was, "far more than a styling exercise." We've since heard that Hyundai believes that a CUV/SUV model offers the best option for customers buying a fuel cell vehicle. Earlier this year, Hyundai's head of the company's fuel cell research, Sae-Hoon Kim, said that, "all customer feedback says range and boot space are the priorities." The Intrado concept had a supposed range of around 375 miles. What that would translate to outside of the fictional auto show universe is unknown, but it sounds like Hyundai is ready to make all of this more real.

Hyundai to recall 27,500 Genesis sedans over brake issue

Following an investigation launched by the National Highway Traffic Safety Administration earlier this week, Hyundai will reportedly recall 27,500 Genesis sedans due to braking problems. Roughly 40,000 Genesis sedans from the 2009 model year were originally under investigation, but this official recall affects vehicles from 2009 to 2012.
A Hyundai spokesperson told The New York Times that brake fluid may cause the brake control unit valves to corrode, which reduces braking power. Affected cars will have their brake fluid replaced, and if necessary, will have the control unit replaced, as well.
The original NHTSA investigation was launched after the government agency received 23 complaints from owners citing reduced braking power and increased pedal travel. One incident reportedly resulted in a crash, while another caused a driver to lose control of the car. NHTSA has not officially announced the recall as of this writing.
