Austin Robot Technology attends Urban Challenge Participant's ConferenceMay 20, 2006
Austin Robot Technology attended the Urban Challenge Participant's Conference, held at the Hyatt hotel in Reston, Virginia. More than 300 engineers, scientists, students and backyard innovators gathered to hear details on DARPA's third Grand Challenge: the Urban Challenge scheduled for November 3, 2007.
"The Grand Challenge has been an unqualified success in attracting robotic enthusiasts from all walks of life to develop technology that will someday save the lives of American men and women on the battlefield," said DARPA Director Dr. Tony Tether. "The Urban Challenge is a more difficult problem to solve than what competitors faced in Grand Challenge '05, but I believe the participants will come forward with innovative solutions. I'm thrilled that so many people want to compete. There is every reason to believe these enthusiasts will accelerate autonomous ground vehicle technology faster than what would be possible with traditional research."
DARPA announces Urban ChallengeMay 1, 2006
The Defense Advanced Research Projects Agency (DARPA) of the United States Department of Defense announced that it will hold a third Grand Challenge for Autonomous Robotic Ground Vehicles on November 3, 2007.
Teams will compete to build an autonomous vehicle able to complete a 60-mile urban course safely in less than 6 hours. To succeed, vehicles must autonomously obey traffic laws while merging into moving traffic, navigating traffic circles, negotiating busy intersections and avoiding obstacles.
Five vehicles finish Grand Challenge course, Stanford winsOctober 9, 2005
Primm, NV -- The much anticipated robotic race started yesterday -- shortly after a spectacular sunrise -- with the launching of Carnegie Mellon University's H1ghlander, followed by Stanford's Stanley and CMU's second entry Sandstorm.
By the end of what turned out to be a dramatic day of autonomous racing, four vehicles had completed the course as the Gray Team's Kat-5 joined the top three vehicles at the finish line. Team Terramax's vehicle was paused overnight and resumed the race early Sunday morning, completing the course before noon. When the final results were tallied, Stanford University's vehicle Stanley had the winning time of 6 hours, 53 minutes and 58 seconds (6:53:58), closely followed by Sandstorm (7:04:50) and H1ghlander (7:14:00).
"--We came very close to qualifying for the race," said Austin Robot Technology's team leader, "--Only 27 teams completed a full run at the NQE but DARPA was able to invite only 23 teams to the race. We missed the cut by four, but we are extremely proud of what our small team of volunteers was able to accomplish in only nine months."
195 teams entered the DARPA Grand Challenge competition, 117 teams were awarded site visits by DARPA, 43 teams qualified to compete at the National Qualification Event and only 23 teams were invited to participate in the actual Grand Challenge Event. The team from Austin built and designed their vehicle in nine months, including the design and implementation of their own drive-by-wire system. The team was ranked 13th after the first day of competition at the NQE.
NQE results announced, Austin Robot Technology misses cut by fourOctober 5, 2005
Fontana, CA -- The closing ceremony for the 2005 DARPA Grand Challenge National Qualification Event was held today at the California Speedway. DARPA Chief of Staff Ron Kurjanowicz and DARPA Director Dr. Anthony Tether entertained the crowd as they announced the top twenty finishers.
"--They put on a good show... it was very funny!" said Austin Robot Technology's team leader. Dr. Tether first congratulated all 43 teams and then proceeded to list the top 20 teams, 'In no particular order', he said. He then listed only 19 teams and said 'That's it', deliberately skipping Red Team's Sandstorm. You could hear the murmurs and the surprised reaction in the crowd. The skit continued as Dr. Tether conferred with Ron Kurjanowicz and both looked at the list again before saying 'Oh, yes, one more, Sandstorm!'
Dr. Tether continued the entertainment and asked the crowd whether DARPA should keep the list to 20 or invite a couple more teams. "--Make it 24 Tony, please, make it 24!" came a reply from the crowd. Dr. Tether then announced he wished he could bring all teams to Primm, but he said DARPA could only invite 23.
"--We had a few failures that cost us a qualifying spot," said Austin Robot Technology's team leader, "--We had a real heartbreak during one of our runs when our lasers became blinded as our vehicle faced directly into the early morning sun. About half the teams at the NQE knew how to set their SICK lasers into 'High Availability' mode which prevents the laser from shutting down due to excessive glare, but the other half didn't know the magic setting. Our third run ended prematurely as our vehicle obediently applied full brakes when the lasers stopped responding. After our run we called SICK technical support and they immediately gave us the 13 steps required to configure the laser to prevent shutdown. It is a real shame we didn't know about this setting before the NQE."
"--We had another setback when our track run came much earlier than anticipated due to faster scheduling of teams when DARPA started running two vehicles at once through the course. We were skipped for a practice run and a software glitch caused our vehicle to make 219 unscheduled stops along the course, stopping for 10 seconds each time and logging data before restarting. The chase vehicle later told us we went through the tunnel 6 inches at a time, stopping for 10 seconds each time, whereas our first two runs we just breezed through the tunnel. Due to all the unscheduled stops, we recorded the slowest time of all teams, clocking in at an impressive 52 minutes! We were told jokingly that Team Terramax is very happy about that because they are no longer the slowest vehicle at the NQE :-) But if you take away the 2,190 seconds our vehicle spent completely stopped logging data, our run would have been a very respectable 16 minutes."
Many other teams had failures as well at the California Speedway, including fires and several high speed collisions with the concrete barriers.
MARVIN conquers infamous tank trap during Run #4 at the NQEOctober 2, 2005
DARPA's National Qualification Event continues to unfold at the California Speedway in Fontana and the tank trap continues to confound countless vehicles. Made out of 4x4 wooden posts, and covered with reflective foil, the tank trap is nearly invisible to a variety of sensors used in typical Grand Challenge vehicles. "--With it's sharp angles and reflective surfaces, it is almost as effective as the Stealth bomber in becoming nearly invisible to lasers and radars," said Austin Robot Technology's team leader. "--A lot of teams can't see it. Earlier today a team just rammed straight into the tank trap and pushed it all the way to the finish line. Dr. Tether has said he reserves the right to put the tank trap anywhere in the course."
In a nail-biter of a finish, Austin Robot Technology's DARPA Grand Challenge vehicle MARVIN wowed the crowd today as it swerved just in time to avoid Dr. Tony Tether's infamous tank trap. The sensors detected the tank trap just in time for a high speed swerving maneuver that caused the crowd gathered at the pedestrian bridge to burst into cheers and applause. Moments later MARVIN applied full brakes after crossing the finish line and appeared to take a bow for the crowd.

Austin Robot Technology ranked 13th as NQE teams complete Run #1September 29, 2005
Ladies and Gentlemen, start your engines, the DARPA Grand Challenge National Qualification Event is underway at the California Speedway in Fontana, California!
195 teams entered the DARPA Grand Challenge competition, 117 teams were awarded site visits by DARPA, and 43 teams qualified to compete at the NQE.
As the second day of competition draws to an end, all teams have completed at least one run through the obstacle course and Austin Robot Technology's vehicle, MARVIN, is ranked the 13th best autonomous vehicle at the NQE. Only 11 teams finished their first run through the course, and only one other team completed more gates than Austin Robot Technology. Their vehicle, MARVIN, is tied for 13th place with ALICE, the vehicle from Caltech. Both vehicles completed 21 gates before being disabled.
"We are proud of being ranked 13th, but we can do much better than we did today." said Austin Robot Technology's team leader. "Anything can happen yet. DARPA is targeting four runs through the obstacle course per team. They have guaranteed each team will get at least two runs, but they are hoping to get as many as six."
DARPA invites Austin Robot Technology to NQEAugust 23, 2005
The Defense Advanced Research Projects Agency (DARPA) announced today that Austin Robot Technology has been invited to the Grand Challenge 2005 National Qualification Event (NQE) to be held September 28 to October 6, 2005 at the California Speedway, Fontana, California. The two other alternate teams invited by DARPA to the NQE include Princeton University and Team Underdawg from San Jose, California.
Forty-three teams are now invited to compete at the National Qualification Event. The NQE will further narrow the field and only 20 teams will advance from the NQE to the final Grand Challenge Event to be held October 8.
Perceptive readers will note a time lag between this entry and the previous entry on this page. "--Rest assured that means we have been hard at work on our robot, if not our website," quipped Austin Robot Technology's team leader :-) "--We have lots of photos of our vehicle and other content we want to publish on our website. We'll start working on it October 9th." :-)

Austin Robot Technology completes initial sonar testJanuary 28, 2005
Austin Robot Technology has completed initial testing of its proprietary sonar sensor. Sonar is one of many sensors which will be used on the team's vehicle to allow it to safely navigate the DARPA Grand Challenge course.
The team is currently working on its second-generation design. "--Our first-generation design has a broad pattern, but our next design will use an improved sensor arrangement which will provide better resolution." explained Matt Bennett, a member of Austin Robot Technology's sonar team.
The sensor uses 40 KHz ultrasonic pulses, and real time signal processing. The sending and receiving units are mounted on a custom rotating arm, giving the sensor a field of view of 180 degrees. The device uses the measured time-of-flight to calculate the corresponding distance and direction of nearby objects, generating images similar to those produced by traditional radar.
Austin Robot Technology selects QuickSilver motor for drive-by-wire steeringJanuary 3, 2005
Austin Robot Technology has selected the Quicksilver 34HC-1 I-Grade Brushless Servo to actuate the steering for its DARPA Grand Challenge entry:
The servo is capable of operation at 12VDC (up to 48VDC). The motor has an integrated encoder with 16,000 line/rev resolution and is programmable via an RS232 interface.
The QuickSilver motor was selected due to it's ability to deliver the necessary torque and RPM combination, allowing us to steer the robot even under the most demanding conditions. The servo will be able to turn the wheels lock-to-lock in close to 2 seconds, allowing the robot to react even quicker than a human driver.
Austin Robot Technology acquires Isuzu VehiCROSSDecember 23, 2004
Austin Robot Technology announced today that the Suzuki-Isuzu dealership of Austin has provided an Isuzu VehiCROSS for the team's DARPA Grand Challenge entry. The outstanding qualities of this little SUV were proven in it's first year of production during the Paris-Dakar Rally and the 1999 Australian Safari Rally where the VehiCROSS won its class.
"--The VehiCROSS is an ideal platform for our Grand Challenge vehicle," explained Austin Robot Technology's President and founder. "--We wanted a 4WD vehicle that would perform well in the desert, had good ground clearance and stability, was manageable in size and had a limited slip differential. With it's sophisticated Borg-Wagner transfer case and one of the tightest rear limited slips on the market it gives us the peace of mind that our vehicle won't spin its wheels if it gets caught on a berm. The Isuzu VehiCROSS meets or exceeds all of our requirements. We are extremely grateful that Suzuki-Isuzu of Austin has provided our team with such an outstanding vehicle. We are very fortunate to have found such a generous sponsor."
The team has decided to design and build it's own drive-by-wire system instead of purchasing an after-market implementation such as those available for people with disabilities. "--Now that we have a vehicle we are looking forward to start designing and implementing our steering actuator." said the team's President. "--We have less than three months before we need to submit our team video for DARPA's consideration and we have only nine months to get ready for the NQE."
The National Qualification Event, or NQE, will be held in September 2005 at the California Speedway in Fontana, California. DARPA will use the results of the NQE to determine which teams are invited to participate in the actual Grand Challenge race to be held October 8, 2005.
