The 2007 Darpa Urban Challenge

Our inaugural episode centers around the 2007 DARPA Urban Challenge, featuring interviews with professor Dan Huttenlocher from Team Cornell and Rick Yoder from Velodyne, a producer of LIDAR sensors used by several teams in the challenge.

Dan Huttenlocher
Dan Huttenlocher is professor of Computing, Information Science and Business at Cornell University in Ithaca New York. As the co-leader of Cornell’s racing team for the 2007 DARPA Urban Challenge, he spent countless hours testing the autonomous car which finally finished among the six final automobiles capable of following California's road code over 56 miles of a mock urban environment. With design in mind, his team of 13 students managed to discretely embed a slick black 2007 Chevy Tahoe with a Velodyne LIDAR, three IBEO 1.5D LIDARs, five 1D SICK LIDARs, five millimeter-wave radars, and four cameras. Of course, millions of data points per second don't come for free and Cornell's trunk is the home of 17 dual core processors.

Since a pile of impressive hardware and CPU is not enough, Team Cornell developed the software needed to allow their robot to locally represent its location on the road and further figure out, on a more global scale, where it really was in the world. However, knowing where you are isn't nearly enough, you also need to be able to figure our where other objects are and ideally track them and reason about their next moves. So, what went wrong in this little fender bender with MIT's car (see video below)? I guess the professional human drivers during the challenge weren't wrong, when they said that Cornell's car drove like a human.


Velodyne LIDAR
Robots: Episode1 Rick Yoder is an employee at Velodyne, a new-comer in the field of LIDAR (Light Detection and Ranging) sensors. The HDL-64E LIDAR uses an impressive 64 stationary lasers on a base rotating at 900rpm. This sensor was specifically designed for the 2007 DARPA Urban Challenge, and was used by around a third of the participating teams, although some other teams may have been turned away by the hefty $75,000USD price tag! Though not yet destined for the consumer market, Rick hints at a new series of sensors that may soon find their way into your home.

Hey!

It was great to speak with Dan Huttenlocher who gave a very interesting talk here at the EPFL.
I was personally amazed with the speed at which the robotics community is striving towards autonomous cars. There's been a huge step since the already spectacular 2005 Darpa Grand Challenge and its desert roads. When I asked Prof. Huttenlocher why he wanted to participate in the Darpa Urban Challenge, he said "Because I thought it was impossible".
Well I guess not, and if 13 students could pack-up todays robotic technologies and create a robot car for urban environments in just one year, then we might not be that far from seeing these cars in our streets soon.

Autonomous cars.... bring it on...

[Bender]

Yeah, it's crazy. Just a few years ago the best teams didn't even manage to do the desert track and now we have several teams completing the Urban challenge... I wonder what DARPA comes up with next...

Guess you don't have to look very far ... the answer's right here on the forum: viewtopic.php?f=9&t=43&p=81&hilit=chembot#p81

I guess a next logical step would be a challenge to automate convoys. That's what they need to run their military supply chains in autonomous mode. And it would be quiet useful for cars as well ... just hit a button once you're on the highway and your car joins the chain of moving cars.

If you have some data on the car's weight and brake performance this could make convoy driving much safer. And you could safe tons of gas by slipstreaming.

Whose, mine? So you can spam me? No way!! :>

But you can probably contact an individual user by sending him a private message through the forum ... (not me though :> hehe! )
