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 refining dealer strategy for premium models

Automotive News reports Hyundai is set to give its sales strategy for premium vehicles a once-over. Moving forward, each of the automaker's five North American regions will have a premium product operations manager. Those managers will all report directly to a senior group manager based at the Hyundai headquarters in California. To begin with, the group will start by identifying what dealers are currently doing right to sell the automaker's luxury hardware. From there, the group will then help spread those practices to the 320 dealerships currently authorized to sell the Equus. All told, Hyundai has some 800 dealers in the US.
The move comes ahead of the launch of the second-generation Genesis and Equus. Both sedans are slated to hit showrooms by early next year. The Genesis debuted in 2008 with the Genesis Coupe following along in 2009, while the Equus first landed on US shores in 2011.

Quality issues drive resignation of Hyundai R&D president

Hyundai released a statement Monday announcing that its research and development president, Kwon Moon-sik, and two other executives resigned from their positions, Reuters reports, to "take responsibility for a series of quality issues," according to the statement.
The resignations seem to be related to recent recalls around the globe. A few weeks back, Hyundai recalled 27,500 Genesis sedans from model years 2009 to 2012 in the US for brake fluid that doesn't prevent corrosion of the electronic hydraulic control unit. The recall recently was expanded to include 43,500 Genesis sedans in the US, but nearly 150,000 are reportedly affected including the South Korean market.
"The latest personnel change shows our firm commitment to quality management and reaffirms our will to continuously improve R&D competitiveness," says Hyundai.
