DARPA Grand Challenge Kicks Off March 13th
GillBates0 writes "A quick reminder that the DARPA Grand Challenge is due to kick off March 13, the coming Saturday." He points to this "quick recap of the teams participating in the event," as well as details about the available satellite feeds. "The Atlanta-Journal Constitution is running a story about the event today. Quoting Frank Dellaert, co-director of Georgia Tech's robotics lab from the article, 'I would have trouble driving some of these roads myself. I think it's beyond the capabilities of autonomous vehicles today.' (shameless school plug). We'll see if the participants can prove him wrong."
Iphtashu Fitz adds a link to the New York Times' coverage of the trans-Mojave race, whose participants include "among other things a seriously tricked out motorcycle. The race is being run by the Pentagon, who is offering a $1 million prize to the builders of the first robot to successfully navigate a 200 mile route across the desert. ... a blog on ScienceBlog about the race has just started as well."
I don't think you're going to get six good laser rangefinders for $5000. I don't remember the numbers as well as I would like, but I think the current favorite rangefinders (I think the brand is SIC?) are well over $1000 each. And you will quickly exhaust your laptop's computational power just denoising the output from crappy sensors. Heck, maybe even for the best sensors.
Autonomous vehicles have already driven across the country on highways, 98.2% of the time without human intervention. The roads it drove on are (I'm guessing) likely to be much nicer than those in the desert. Furthermore there was a human available to handle the surprises. For humor value: I believe one of the self-driving vechicles from CMU has a learner's permit from the state of Pennsylvania. See No Hands Across America for more info on this project.
The hard part of any project like this is uncertainty in the environment. The road may "disappear" completly from your sensors, or you may spot multiple roads. Maybe some mica on a rock screws up your rangefinder. Maybe your vehcicle's transmission gets a little "funny" and you can't shift properly anymore (I saw such a comment attached to this article). And we aren't even talking about genuine malfunctions like a failing rangefinder or sticky throttle.
I think autonomous systems might be the best example of the best laid plans of mice and men not succeeding when the slightest thing goes wrong. In fact, Steinbeck's story seems directly analgous to the problems of self-driving vehicles.

More likely is that they want other people to research how to build a future battledroid to capable of military-level spy/front-line army work... capable of survivng desert conditions for a given number of miles.
READY.

I'm disappointed that there is not more information available about this event as it happens. I've been following it vicariously for months, and now I'd like to hear about what is happening at the speedway in Fontana. How many teams showed up? How many tried out today? Which passed, which failed? I haven't been able to find out any of that information.
The so-called Science Blog article was from February 10! That's not exactly timely, is it?
Nagle's later posting here does present some information about Caltech. The Caltech team web page provides the same basic info, with a little different spin. But I guess we're lucky they posted today; the previous entry on the team's news page was dated November 16, 2003.
CMU has been updating almost every day, but their last entry was Saturday, saying "The curtain goes up Monday morning". Again, what happened?
You'd think in this age of bloggers, when every windbag on the net sees fit to tell us what he had for lunch that day, someone would be watching this event and posting some updates in the evening. If this isn't happening, I beg anyone who is attending to step up and start writing! Maybe I'm spoiled by the usual instant access to information, but I'm passionately interested in this event and starving for news.
