It was inevitable that eventually, someone’s self-driving car would be in an accident involving a pedestrian…and a 49 year old woman in Tempe, AZ, pushing her bike across the street, was the first victim. While the car was one of Uber’s, it really could have happened to any of the tech companies. Details are still scarce as the investigation continues, but it’s safe to say that the car stored massive amounts of data that will make for a quick conclusion.
Startup Kitty Hawk unveiled their autonomous flying taxi, called Cora. Designed to be a self-piloted, electric-powered, passenger-carrying drone service, the business model is hardly new, but their approach to the technology is. They’re combining a traditional aircraft with pusher prop and wings, with a multi-rotor (12, to be precise) drone-like configuration for vertical thrust, allowing true vertical takeoffs and landings. No word on when you’ll be able to get a ride in one, but considering they have a flying prototype and financial backing from Larry Page, it’s a matter of getting the software right, and finding a way to certify this for use in the various countries (they’re starting out in New Zealand for precisely that reason, the country is more business-friendly for technologies like this).
As a quick side note…if you check out their website, note they did something clever with the scrolling..you scroll UP, not down like every other page on the internet. Nice tie-in with their technology and slogan (“things are looking up”).
The days of gas-powered cars are numbered. Sure, electric cars are cool and promising and are gaining in popularity worldwide, but an announcement by Volvo really helps make clear the powertrain of the future. As reported by MotorAuthority, Volvo is no longer working on any next generation gasoline powered engines. This doesn’t mean they’ll stop SELLING them any time soon…the current generation can last quite some time, I’m sure. But they’re looking ahead, and they apparently don’t see the profit in developing new gas engines, not with the rise of electrics. A big step, really, and one I expect other car companies will emulate. Or…maybe it’s just a publicity stunt? Volvo is owned by Chinese company Geely…so are they making this announcement for the eco-friendly news benefit, while actually planning to switch to Geely engines in the future if electrics haven’t reached the point needed by then?
Also in electric vehicle news…delivery company DHL did the math on Tesla’s new semi truck, and figured they’d break even on it in less than two years, compared to a conventional diesel truck. For large companies that are willing to invest in capital equipment like this, switching their short/mid range fleets to electric is really a no-brainer! It’s only a matter of time, too, before trucks like the Tesla are suitable for long-haul trucking.
Lately I’ve been pretty optimistic about self-driving cars…the technology seems to be maturing so quickly, I’ve been expecting them to become commonplace in a matter of years, not decades. A recent photo from Apple has me questioning that – and it’s not a problem unique to Apple, all self-driving automotive technology currently has this limitation.
Take a look at that picture, what do you see? An incredibly complex array of optical-based sensors. Some are lasers, some are cameras. All self-driving cars use something similar, at least based on what’s publicly known right now (GPS is also used, but it just provides approximate location, with no insight into obstacles on the road).
So. Optical sensors. What happens when the lenses get dirty? I used to live in CA so sure, out there they can stay clean for months. Or, as Apple recently announced, the technology can be improved to deal with some raindrops on the lens. But drivers in most of the country have an honest four seasons to deal with, and of course the worst is areas with snow. Not just for the snow that can accumulate on the lenses, but when that snow melts, the dirty airborne mist kicked up by other cars coats your own in a deep layer of muck.
The automotive industry has developed washers for headlights to partially address this problem, but those are imperfect…but maybe good enough for this application? Ideally, I think a true wiper-based solution is needed for each lens.
How will this be solved? I really don’t know…maybe improving the technology used to clean some car headlights. Until then, I do expect self-driving cars to become commonplace, but only in mild-climate urban areas.
Rental cars can be fun! Some say a rental car is the ultimate off road vehicle. For me though, it’s a great chance to examine different product design philosophies, in some of the most expensive consumer products on the market. On this trip, my rental car was a bright blue Toyota Yaris…a class of rental car I usually avoid but have been curious about.
So, the good: drop this car into a low auto gear (3 or 2), and it’s a peppy, fun car that reminds me a lot of a Mini Cooper. Driving dynamics are downright decent.
The bad: everything else. No, really, the stereo is one of the most counter-intuitive I’ve seen. A peice of plastic trim came flying off when I removed my laptop bag from behind the driver’s seat. The brakes work eventually. The driving position is reminiscent of bad Italian design from decades ago, with arms extended and legs crunched up around either side of the wheel. The worst design detail though? The door locks, I haven’t had a car without remote locks in ages, but that’s not a big deal. What’s bad is how the locks work. Unlock the doors by rotating the key clockwise. Ok. Got it. Now unlock the rear hatch…by rotating the key *counter* clockwise. What kind of moron decided they’d actually ship a mass produced vehicle like this? Redesign the locks so they work the same, it’s just idiotic to do otherwise.
A functional hoverboard, due to ship in 2015, has all the makings of a hoax (remember Back to the Future?). Except…I’ve been digging…and this appears to be genuine. The exact technical details aren’t clear…but from what I can gather, both from the official page and from comments on Kickstarter, it uses a rapidly changing (rotating?) magnetic field that creates eddy currents in the surface below, which then produce an opposing magnetic field. You do have to be over a conductive, non-ferromagnetic surface (aluminum or copper sheet, for example), but…it works!
HENDO has a Kickstarter campaign to help raise money for this project, and they’ve already surpassed their funding goal with 53 days to go. Check out their video to see this in action:
Not surprisingly, this technology is getting a lot of press…you can read more about it in the New York Times, Business Insider, or Forbes. Note that it only works over special surfaces, and battery life is limited…but these are relatively minor hurdles to overcome when designing products incorporating this technology. That’s what it comes down to, too…the hoverboard is just a marketing gimmick, the company’s goal is to license the core technology. Possibilities…
The DDS from Daymak looks to be an easy way to convert most any bicycle to an electric-assist bike. The wheel contains its own battery, motor, and even solar panels to charge it (~.6 miles range per hour of sunlight). It looks like it’ll only work with V-brake bikes (not disc), though will be available in either a 26″ or 28″ rim size…for about $700 next year. The 250W motor is powered by a 12Ah lithium battery and controlled by a wireless handlebar-mounted controller (with its own solar panels, too). Interesting idea! I could see this being useful for commuters perhaps. The extra mass and rotational inertia will detract serious bicyclists though. Check out the product page here.
