NQE Test, Monday, Oct. 29, Course B , Run#2
Boss took a second crack at the parking lot
and narrow, winding roads of Test Area B on
Monday afternoon. It's proven to be a tough
course, with only Boss and three other robots
completing it in the first three days of the
NQE. This run included a couple glitches and
took a few minutes longer
than the initial run on Saturday, but, all in
all, "it looked pretty darn
good," said Chris Urmson, director of
technology.
The run was delayed for several hours while
DARPA officials made changes in the course
and because of glitches in DARPA's emergency
stop system.
Once underway, Boss was its typically
aggressive self.
At one point, Boss began backing up,
eventually rolling up onto a curb.
DARPA officials paused the vehicle but, with
the road clear ahead of the robot, Tartan
Racing members urged DARPA to put it back
into autonomous mode. Boss moved forward
safely. A bit further along the same street,
near a line of parked cars, Boss backed up
and moved forward several times, as
if trying to avoid an obstacle. The vehicle
eventually stopped this maneuver and was able
to complete the run.
Team members were reviewing data downloaded
from Boss to determine what caused the
unusual behaviors. "Maybe there's something
to fix, maybe not," Urmson said.

Carnegie Mellon's Tartan Racing team
qualified for the race to be held on
Saturday, November 3, 2007.
Here is an excellent video showing "Boss" in
full autonomous mode. Yes, that means the
car is driving itself... No remote control.
No magic tricks. Boss can see, makes
judgements and drive.
The camera views were downloaded from the
vehicle after the successful run.

| Boss NQE Test, Sunday, Oct. 28 - Darpa Urban Challenge |
 |
Boss delivered another strong performance on
Day 2 of the NQE. The test assessed the
ability to handle cross traffic and oncoming
traffic and to make safe left turns across
moving traffic. The test is a variation of
'chicken' from the old days of hot-rodding,
but this is played out with robots and humans
sharing the road. A dozen human drivers
created dense, two-way traffic and Boss found
its way through it. Boss had to find gaps,
choose opportunities to enter and cross
traffic, and make its way around a
'belt-buckle' shaped course.
Boss completed 16 circuits of the course in
the allotted 25 minutes. That is best-yet,
but more is possible, and some great
competitors have not yet run this. The
next-best performance so far is 11 circuits
scored by Virginia Tech.
"All in all, it looked like the vehicle did a
kickass job out there," Chris Urmson,
director of technology, told the team when it
gathered for a post-run briefing.
During the test, Boss had to cross the
belt-buckle on the center road while human
traffic flowed continuously at every turn and
every intersection. Boss had to repeatedly
read and shoot the gaps. Too much boldness
and Boss would disrupt traffic. Too much
hesitation and opportunities disappear.
A perimeter of jersey barriers encroach on
the outer lane, so the course is tight and
unforgiving -- traffic or no traffic. The
lanes are only 11-feet wide (versus the
standard 14 feet), so Boss had to thread the
gap between oncoming traffic and the rail.
Boss made the turns across traffic without
incident and drove aggressively so it could
complete the 16 laps in the allotted time.
The run was not without flaws. Human drivers
gave Boss a horn or two. Several times, it
stopped abruptly as it was driving along the
jersey barrier and approaching the end of the
oval. At one point, it stopped short of the
turn point at the middle of oval and, at the
request of the team, DARPA officials
momentarily paused Boss. At another point,
Boss knicked a curb to avert oncoming
traffic. Team leader Red Whittaker commented
that "The belt-buckle is an unnervingly
difficult event. We are thrilled that Boss
drove well and survived crash-free. This
wasn't perfection, just best-of-class so
far."
The team is analyzing these and other minor
incidents to make adjustments. It is likely
that Boss will face other tests on this same
belt-buckle course during the week.
It was the second strong performance for
Boss. Two other teams - MIT and Germany's
Team Carolo -- have completed the long,
narrow, winding roads with parked cars and
other obstructions in Test Area B that Boss
aced on Saturday.
Tomorrow, Tartan Racing will complete the
first round of NQE testing at Test Area C,
where vehicles display their ability for
tight maneuvering, handling four-way
intersections and finding alternate ways to
reach blocked goals.
