1997 Contest
Oakland University and the U.S. Army Tank-Automotive Armament
(TACOM)
hosted the International Ground Robotics Competition
on May 31- June
2, 1997 in Rochester, Michigan. A team consists of from
3 to 15 student
members, at least one faculty advisor and possible their
sponsors.
The students can be undergraduate or graduate students
from any major.
The most popular majors for contestents are in mechanical,
electrical,
electronics, computer and computer engineering as well
as computer
science.
During the previous four years, 57 teams have competed
in the event
with over 600 students from 22 universities.
There are two competition events: the Vehicle Performance
Competition
where the autonomous robotic vehicles compete to finish
a course in
the shortest time, or by traveling the farthest distance
in the
allotted time; and the Vehicle Design Competition that
evaluates the
documentation, management and presentation of each team.
The performance competition require the autonomous vehicles
to sense
lane marking lines, avoid obstacles, stay within the
lanes and adapt
to differing line patterns, colors and quality, travel
across ramps
and go through sand traps.
The design competition
requires the team to submit a technical report
a month prior to the main competition documentation their
design,
approach, team and resource management and present a
10 minute talk
detailing their approach. They demonstrate the vehicle
hardware and
answer and questions the panel of judges may have. This
part of the
competition challenges the students to pay attention
to the importance
of documentation, presenting, promoting and defending
their project.
The Association of Unmanned Vehicle Systems International
sponsors the
1997 competition with the Society of Automotive Engineers,
Oakland
University, Fanuc Robotics and Ernst and Young as co-sponsors.
The
competition awards more than $12,000 in prizes to the
first, second
and third place winners in each event.

The Schedule
The UC team packed three vans and left for Detroit about
10 PM on Friday, May 31 since they were scheduled for an early presentation
on Saturday. They arrived at the hotel about 3 AM.
They unpacked their vehicle early on Saturday, June 1,
and prepared for the qualifying and practice runs. They also prepared for
their presentation before the team of judges in the early afternoon.
More design presentation were held on Sunday June 2. The
teams were busy with qualifying and practice runs. A welcome ceremony and
design award presentations were given at 5 PM. The UC team won an Exemplary
Design award.
Our team had not been able to qualify on Sunday and had
to arrive at the test ground at 6 AM for a qualifying run on Monday, June
3. The competition was delayed because of rain but finally started in the
rain.
Our best run came about 7 PM on Monday. Our robot went
325 feet
before it ran into an obstacle, the money bucket which
was marked with a
green $.
We packed up and left about 9 PM and one van arrived back
in Cincinnati at 3 AM and the other two at 10 AM the next morning.

Faculty Advisor's Comments
This was our fifth year in the AUVS contest
but we still ran into a completely new situation - running
our robot in the rain! In the previous years it never
rained.
In fact last year in Orlando, it was so hot and humid
that it was
really hard to work. This year it rained and rained and
rained.
The contest organizers had three choices. They could
have cancelled
the contest. Then we would have all been disappointed.
They could
have delayed the contest or rescheduled it. Then we and
they would
have been out of funding. So they ran it in the rain.
I am really proud of our team. They
worked harder and smarter in the most unusual conditions.
Who takes
their computer out in the rain? We had hardware problems
that I had
never seen before such as a battery post melting, software
problems
that got worked out at the last minute, and the weather.
The team from Hosei University were the first ones to
cover their
robot in plastic, put on ponchos and test in the rain.
Since they had
their Dean of Engineering with them and had come a very
long way, they
were determined to win.
Looking back I see that the biggest mistake I made was
this Spring when it rained, we didn't go out and test.
We did a lot of things right and are now preparing technical
papers
for the Intelligent Robots Conference this Fall.
The fuzzy logic controller is unique and novel and works.
The fault diagnosis system also was a splendid idea and
taught us all a lot about anticipating things that can
go wrong.
The ultrasound systems were solidly designed. The steering
systems
worked well. The speed control was fine. The vision system
was
splendid.And the remote emergency stop system worked
well.
Our team worked together well and overcame many problems.
For next year, I think we should start this Summer if
we are to
continue with the contest. The papers we are now writing
will help
everyone understand the design.
It was a great experience.
