- we should start out by explaining our name. After about 45 minutes
of looking up random words in the thesaurus and dictionary, we came
across Themis. In Norse Mythology, Themis is the Goddess of Physical
Phenomenon. And so it was - what better name to use for our team this
bold and domineering title!
But that is skipping ahead. We started with four. Francis, Gilbert, and
Billy heard about the competition through their friend Eric. "Why not?"
he asked. It sounded like such an innocent project.
After school, on a relaxed Friday night, we went to our first meeting at
Lockheed Martin. As it turned out, by the time we sat down and started
listening to some of the other teams from different California High
Schools talk, we knew that we were about to jump into a project bigger
than the four of us had ever experienced or even seen. After viewing a
video of the previous year's competition, and after seeing the amount of
work, skill, dedication, coordination, Coca Cola, and stress that needed
to be put into it . . . we couldn't stop talking about it for the next
three hours.
About a month went by, and we had managed to con about 38 students into
joining the team. There were a few sophomores, about half juniors, and
around ten seniors. What kept us motivated was the sheer rush that came
from knowing that we were about to spend two months of our lives trapped
at school planning, designing, constructing our own robot - and these two
months were right around the corner. Everyone was excited, but they
didn't quite know what was about to commence. We didn't know what was
about to commence. And then the deadlines started appearing.
The first deadline was the entry fee. $4,000 was supposed to be sent to
the FIRST Foundation in about two weeks. We had nothing. Immediately
following this profound realization, we scurried to create multimedia
presentations, buy suits, and work on our speaking skills. We then
scheduled a presentation for our school's Student Congress. With that
money and money collected from other personal contacts, we were able to
make the deadline. A few days late, but they accepted it. Fairchild
Semiconductor ended up being our main sponsor about a month later. And
then the next deadline showed up.
Another month rolled by and we realized that we needed to send someone to
New Hampshire (We're in the Bay Area) to register us formally and pick up
the containers of parts we needed. Through the powers that be, our
principal just so happened to be planning to go to New Hampshire at that
time. We got our parts.
And then along came January 10. The FIRST Competition was formally
started. We downloaded the rule book off of the team area of the FIRST
Foundation's web site - where all 200 US teams were told to look for it.
It was just posted up on their page the night before. We started to look
through it. It was over 200 pages long. We were in need of a faster
printer.
A few days later, we started designing the robot. We held meetings at
school, at people's houses, and anywhere else were we could fit 25 people
at a time. At times our group was divided into 5 teams, each working on
a general design of the robot, all completely different. After
synthesizing our designs (it took about a week), we had a general idea of
what we wanted to build.
Of course, the word 'design' in the technical field is often associated
with CAD. So now we had to model our robot in AutoCAD. This is where we
fell a little bit short. Only one and a half weeks out of our six week
allowance had been used up, and we were already trying to build the
robot. The designs were not finalized yet, but that was OK - we had 38
people hyped-up and ready to spend all hours of the night at our school's
metal shop - we didn't need designs!
We were given two crates of parts, around 1000 parts total. There were
no instructions. The only thing we knew was that we had at our disposal
motors, gears, pneumatics, electronics, and various fasteners and
components, as well as a catalogue of parts that we were allowed to order
from.
Alas, we ran into troubles. The pieces didn't fit, the holes weren't
drilled to spec, the angle iron wasn't cut to the right length, and our
welding warped the frame. We realized that, among other problems, this
was the direct result of not finalizing our design correctly. About 3
weeks into the process, we decided to model as much as we could on the
computer. AutoCAD was simply not fast or simple enough for us to
efficiently use. Rhino3D, a software program comparable to AutoCAD, was
employed. The models created there were certainly giving more shape,
definition, and concrete measure to the design, but it was too abstract.
The solutions to our problems still had to come out of our heads and then
directly into the metals shop. We just didn't have enough time to sit in
front of the computer and model everything to make sure it worked. We
just had to build it.
A valiant effort, indeed it was.
But, being the resourceful and ever-dedicated team that . . . we knew we
had to be, we pulled through. The claw on our robot was designed by
hand, built out of fiberglass, and controlled through an air piston
attached to an accumulator, hooked up to our pump, wired to the
controller board. The lift was built using fiberglass, metal rods,
pulleys, spectra-cable, and a few motors here and there. The base was
constructed out of angle iron, and on it went the wheels and motors,
gliders, a motorized platform for the lift, the pneumatic systems, speed
controllers, the controller board, 12v battery, an R-Net, and an
assortment of colorful cables.
The last few nights of construction, we were running around from the
physics room to the metals shop to the woods shop and back again. Five
of us trying to solve this problem, and seven on that problem, and the
remaining trying to re-design the structures that the problems were
attached to - all knowing that the robot had to be shipped to Florida in
three days.
But through hard work, a few skipped school days (though the days were
spent entirely at our school's metal shop), 26 McDoubles per night, and
many a cup of Surge, we got the robot packaged, and delivered to UPS.
With two minutes to spare.
That was quite a trip in itself. A month and a half of planning,
designing, constructing, troubleshooting, and re-designing was about to
pay off at the Epcot Center. In Florida.
So, as April 2nd came to be, and after a few months of rest, relaxation,
and reflection, it was time to compete at Walt Disney's Epcot Center.
21 of us, including two advisors, flew down to meet our robot. We spent
a total of five fun and stress-filled days and nights planning,
repairing, preparing, competing, partying, sleeping, staying up, more
repairing, re-designing (yes, even in Florida we redid parts of our
robot) and finally competing in the final matches. We didn't place that
high. But that was no longer what mattered. In fact, for a lot of
people that was the last thing on their minds.
What all of the sudden came into focus was the following year. We knew
that there were quite a few things that went wrong, and we had an entire
summertime to plan out and organize the ideas for the team. And here it
is, August 6th. School starts at Mills High School on the 31st, and
we've only got 3 months until the entire process starts over again.
An entire year has almost gone by since we first started the project.
Memories of laugher, compromises, stress, glee, more stress, learning,
and great times lay behind us. But there are plenty more of those right
ahead, as we enter the FIRST Competition 1999.
