Aurora's Chris Urmson on autonomy — that's one way to avoid speeding tickets

Although this year's CES was full of companies announcing and exhibiting their real and conceivable self-driving car technologies, while actual self-driving cars from Aptiv-Lyft were giving conventioneers 400 rides around town, the biggest news came when Volkswagen Group — and recognize this is the entire group, not just the brand — and Hyundai announced that they'd both partnered with Aurora Innovation. While the VW announcement was vague — "The collaboration brings the two companies together to realize self-driving electric vehicles in cities as Mobility-as-a-Service (MaaS) fleets" — Hyundai provided a concrete goal: "a strategic partnership to bring self-driving Hyundai vehicles to market by 2021." You may not have heard of Aurora, which has been described in some news accounts as "mysterious." But Aurora Innovation has been in business since December 2016, and it is to autonomous technology what the 1927 Yankees are to baseball. The three leaders of the company are Chris Urmson, co-founder and CEO, who had previously been chief technology officer for Alphabet Self-Driving Cars; Sterling Anderson, co-founder and chief product officer, who had directed the development of Tesla Autopilot; and Drew Bagnell, co-founder and chief technical officer, who had been autonomy architect and perception lead at the Uber Advanced Technology Center. We had the chance to sit down with Chris Urmson after he appeared onstage at a Hyundai press conference. He shared his insights on Aurora's approach to automated driving. Initial deployment of self-driving cars? "We think the first place this technology comes to market in in the transportation services or ride-hailing applications, but that's for our partners to decide." (Ride-sharing is a strategy a lot of players in the field are shooting for, as round-the-clock use is one way for paying for what will initially be a technology too costly for private ownership.) Transporting goods or people? "I personally — and as a company — am more excited initially about moving people around. Urban mobility. That's where you see the largest social impact. And it provides better access to mobility for people." Can you create a car that doesn't crash? "It is a fundamentally hard problem because other operators on the road can behave erratically at any moment. For example, if you are in a two-lane, opposing-traffic road, if you want to be safe, you don't drive there, ever.

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.

My year in EVs: 8 electrics that are changing the car industry

The year 2021 will go down as an inflection point in the auto industry’s transition to electric vehicles. It's when many much-anticipated models became reality. No longer sketches or sketchy prototypes, electric vehicles appeared from all corners with everything from the Lucid Air to Ford Mustang Mach-E changing how we think about transportation. I managed to drive a lot of them, and as I went through my notes, I realized IÂ’ve got a mini memoir of the seminal EVs of 2021. HereÂ’s my take on eight of them. Hummer EV Easily the most over-the-top EV I tested this year. The 1,000-hp super truck lived up to the hype with its domineering presence, stupendous power and simply being a reincarnated Hummer. I took it for a short spin on- and off-road at the General Motors Proving Grounds in Milford, Mich., and was impressed with the airy cabin, removable sky panels and expansive touchscreens. Yes, I crab walked, which felt like steering a pontoon boat, though I can see why it would be useful. Lucid Air Dream Performance The most beautiful sedan I tested all year, EV or otherwise. Unlike the futuristic Mercedes EQS — which is quite attractive — LucidÂ’s car is a blend of mid-century modern interior aesthetics and classic European exterior styling. When I walked up for my test drive, someone who IÂ’m pretty sure was comedian Jon Lovitz was sitting inside and taking it all in. As it sat in the valet of a hotel in a wealthy suburban enclave north of Detroit, the Lucid drew more attention than any of the Mercedes, Cadillacs or Lexus models passing by. The driving experience was enveloping. Starting at $169,000 for the Performance model (reservations are closed), the Lucid I sampled packed 1,111 hp and 471 miles of range. From the precise steering to the comfortable suspension, the dynamics were spot-on. It's a formidable product, and all the more impressive given itÂ’s LucidÂ’s first. Chevy Bolt EV The Bolt was the most pleasant surprise for me. It handled well, offered low-to-the-ground hot hatch dynamics and the steering was dialed-in. Adding a crossover variant for the new generation was a smart play. On a summer morning where I went to a first drive of the Ford Bronco at an off-road course, my hour-long commute in the Bolt was an enjoyable appetizer.  The Bolt was also my biggest disappointment due to its extensive recalls for fire risk. Ironically, I had the Bolt in my driveway when the initial recall went out for the previous generation (2017-19).
