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, Kia to put solar panels on vehicle roofs

Hyundai Motor Group said Wednesday that future Hyundai and Kia models will be equipped with solar panels capable of generating electricity as a way to increase fuel-efficiency and range and lower CO2 emissions. Hyundai says the solar panels will feature in the rooftops or hoods of select vehicles "after 2019" and will supplement traditional internal combustion, hybrid and battery-electric vehicles. The parent group said it's developing three different types of solar roof charging systems comprised of a solar panel, controller and battery. The first generation will be a silicon solar panel system mounted to the rooftops of hybrid models and capable of charging 30 to 60 percent of the battery per day, depending on weather conditions and other factors, starting as early as 2020. The second generation involves a semi-transparent solar roof system applied to a panoramic sunroof and capable of charging an electric-vehicle battery or a battery mounted on a gasoline engine. Hyundai says the latter configuration will help it increase vehicle exports, since solar-equipped ICE vehicles will be able to adhere to regulations limiting CO2 emissions. A third-generation system is being tested right now. It will add solar production capability in the hood and roof of EVs – but the companies don't provide more detail than that at this moment. "In the future, various types of electricity-generating technologies, including the solar charging system, will be connected to vehicles," said Jeong-Gil Park, executive vice president of engineering design at Hyundai Motor Group. "This will enable them to develop from a passive device that consumes energy to a solution that actively generates energy. The paradigm of the vehicle owner will shift from that of a consumer to an energy prosumer." To date, solar vehicle charging technology has mostly been for light-duty tasks, like cooling off the interior or trickle-charging a conventional battery, such as the system offered in the previous Nissan Leaf. Systems that do more than this have typically come with a very steep pricetag for modest capabilities. Panasonic has developed a 180-watt solar roof available for the Japanese version of the Toyota Prius Prime plug-in hybrid that is capable of adding up to 3.7 miles of range per day – at an unspecified (as of this writing) but undoubtedly high cost. Elon Musk, unsurprisingly, has also discussed making a solar roof optional for the Tesla Model 3.

Hyundai preparing to enter US commercial vehicle market

The commercial van segment has been surprisingly hot in the US over the past few years with new or updated entries from Ford, Nissan, Mercedes-Benz and Ram. Now, it looks like we can add one more to that lineup because Hyundai plans to enter the market here, too. The decision is part of the brand's newly announced push into the commercial vehicle segment worldwide, according to Reuters. Hyundai intends to invest 2 trillion South Korean won ($1.8 billion) into the venture through 2020, and the Korean automaker expects the segment to grow by 30 percent annually worldwide over the next five years. Around 1.6 trillion won ($1.5 billion) of that goes towards development of new models and engines for the division. Another $363 million is for expansion of the company's Jeon-ju plant to build 100,000 units there each year. According to Reuters, there's no set timeline on the US introduction of these models yet. Hyundai already sells commercial vehicles in Korea and China but holds just 2.1 percent of the global market in the segment. Autoblog reached out to Hyundai Motor America to learn more, but company spokesperson Jim Trainor said via email, "It is too early to provide any more details concerning the sale of commercial vehicles in the US market." The company is already setting it sights on the European commercial segment with the HG350 (pictured above). It's offered as either a cargo van or flatbed and is meant to compete against market stalwarts like the Ford Transit and Mercedes Sprinter. Rather than this vehicle, the US might get one of Hyundai's newly developed models, though. The automaker previously suggested to Autoblog that it wasn't "seriously considering" the HG350 for this market, at least at that time. Hyundai Motor Plans to increase Jeon-ju Commercial Vehicle Plant capacity to 100,000 units • Hyundai Motor to invest KRW 2 trillion on commercial vehicle development and production until 2020 • New Pilot Center, Global Training Center expected in Jeon-ju plant • 1,000 new jobs to be created following the increased capacity February 16, 2015 – Hyundai Motor announced today that it will invest KRW 2 trillion over the next six years to enhance its global commercial vehicle competitiveness. KRW 1.6 trillion will be invested on developing new models and engines to strengthen global commercial vehicle competitiveness.
