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.

2015 Hyundai Azera is refreshed, may still be on life support

What you see above is the 2015 Hyundai Azera. It's slightly refreshed for the new model year, with a new grille, lighting elements and fascia joining some newly standard technology bits inside the cabin. Other than those few updates, this is the same Azera we've known and loved since its most recent redesign for the 2012 model year. Thing is, we're not sure if the Azera will actually live past 2015 here in the United States. Hyundai has said that it still sees some space above the Sonata midsize sedan and its larger and more luxurious Genesis Sedan for a vehicle sized and priced like the Azera, but just hasn't been able to find many buyers who agree. Put simply, if you like what you see in the 2015 Azera, now would be a good time to mosey on over to your nearest Hyundai dealer to see if this fullsize sedan suits your specific needs better than competitors like the Chevy Impala, Toyota Avalon and Buick LaCrosse.

Hyundai mulling four-door coupe model, V8 or V6 turbo for next Genesis Coupe

Hyundai is showing no signs of slowing down, with plenty of new product in the pipeline. This, according to a recent Automobile magazine interview with John Krafcik, CEO of Hyundai Motor America.
Krafcik admits the Korean automaker is considering adding a four-door coupe to its lineup, possibly sharing some design elements of the HCD-14 Concept (shown above in Detroit). The brand's flagship Equus luxury sedan will receive a mild refresh, bowing at the New York Auto Show, and an updated Sonata is expected to follow on its heels. The executive dismissed suggestions of an upcoming current-gen V8 Genesis Coupe, saying the present platform cannot accommodate a V8, but an eight-cylinder engine or a turbocharged V6 is a possibility for its eventual successor.
