This is fascinating. I can't believe I never knew this.

You're missing the point. Your argument is it's impossible for someone to make great strides without a traditional education, and I already provided you with two specific counter-examples. Unless I'm lying about the persona

You seem to have a lot of experience and a way of doing things which works for you, and that's fine. Your experience seems to have made you conservative, for better and for worse. Of course people with traditional experience will hav

I'm not sure why you hold such a high regard for degrees. I also got my EE degree from UIUC, and while I think it is/was a great university most of what I learned was self-taught. I'm also a PhD dropout, worked at prestigio

Yep. Supposedly he came from a tiny town where people only hard first names, and when he moved to the US he just became Herman Herman. When I was interviewing there, the recruiter referred to him as Herman squared.

While technically correct, calling NREC a CMU robotics lab is really a stretch. They are surprisingly independent entities - I know this as a former student of Carnegie Mellon and employee of NREC. Most people at CMU, including some of th

"A robot is a device that doesn't work (yet); as soon as it works, it is renamed" I love this definition.

TechShop is great for hobbyists with some money to spare (there are a lot of hidden costs, both time and money, that they don't tell you about), but terrible for professionals. Their machines are regularly not working for days at a ti

At a very high level, instead of comparing everything against a map, we try to figure out what it is. For example, the way Google detects traffic lights is using geometry to infer where a traffic light will be. Their maps are so good that

Agreed 100%. I'd be amazed if a stage 4 autonomous vehicle existed in less than 5 years, honestly I'd guess closer to 10. I do think highway driving can be fully automated within 2-3 years, so Otto makes a ton of sense. I actu

I used to work on this - the approach is very different. That's a pretty hollow statement on the internet though, so take it as you will. An interesting aside - it seems like most of Google's team left this year. Chris Urmson le

The maps Google uses for their self-driving cars, as I understand it, require constant maintenance. Also just the amount of data is huge. If this weren't the case, surely they would have driven in many other places by now? I would ac

How do you know that? There hasn't been a competition since 2007, and that was before Google was involved.

by jayjay71 10y ago
I think it actually doesn't make that much difference. The problem, I believe, is that people are used to rapid advances in software. Lots of small iterations can take you a long way, but sometimes you just reach a hurdle which req

Everybody wants to jump straight to 4, because 3 is actually dangerous and likely to cause deaths as people are lulled into a false sense of safety. The question is how long will it take? Some people say 2 years, some people say 20.

This is the way Google does it as well, and in my opinion is a fundamental architectural failure. There's a reason after several years Google still has tested in so few locations. Delphi has a more robust system (in theory), but the a

I'd love to sit in one of those cars and see how well the cars can drive themselves, especially during the winter. It's just a really awesome experience being in a self-driving car - it'd be amazing if you could just hail on

While I don't disagree with you, I think the real credit goes to Dr. Tony Tether who was the director of DARPA for the duration of the self-driving car competitions. He set aside money for the races and helped design them. After the

The inventory-checking robot is an interesting pivot for Bossa Nova, a company that is 11 years old and originally focused on robots that could balance on a single ball (it spun out of Carnegie Mellon where the original Ballbot was created)

I actually made a mistake. Stanley was the winning entry in the 2005 DARPA Grand Challenge. Junior was the 2nd place winner in the 2007 Urban Challenge.

Don't forget GM also funded the winning team of the DARPA Urban Challenge in 2007, and then let the majority of talent go to Google. Stanford's entry Stanley came in 2nd and is at the Smithsonian National Air and Space Museum. C

I am still amazed that GM managed to lose that IP to Delphi. It was amazing tech (I worked on it).

Sure, the cost will come down. But comparing the cheaper $7k sensor to the original $90k sensor is disingenuous, as the original is still several times better than the cheaper one in terms of FOV. I was referring to IBEO sensors which are

The real issue with Tesla is that they marketed it as a self-driving feature when really they had developed cruise control plus. Lots of manufacturers have had cruise control and lane following with automatic braking for some time, but the

by jayjay71 10y ago
Agreed, but that's because they're actually selling cars. Most people don't realize a single sensor can cost $20,000 - now imagine you have 10 of them. That's an order of magnitude more expensive than the car. I'm

I agree that Volvo has a better approach and from what I can tell the necessary hardware to have a much more robust system. What I'm arguing is that there are too many problems that still need to be solved for them to have a stage 4 a

by jayjay71 10y ago
I love the work that Volvo is doing, but I am highly skeptical they will release a stage 4 autonomous vehicle in 1 year's time. You might be buying into their PR the same way everybody else bought into Tesla's PR.
