Rack ’n' Roll is a game played on a field having two sides, and a center scoring mechanism. Two ALLIANCES,
one red and one blue, composed of three teams each, compete in each match. The object of the game is to get a higher
score than your opponent ALLIANCE by placing air filled inner tubes on the central goal structure (the RACK). The team
with the longest sequence of rings gets more points. In addition, at the end of the game, the team will get BONUS
POINTS if they are able to get to their HOME ZONE and not in contact with the playing field at the end of the match.
Sounds easy huh?
Here is an arial view of the field...
Our game plan had two sides. One was to be able to score, but be stable enough to place two robots
to gain the bonus points. We knew that if we could get one robot 12 inches off of the ground, we could possibly get
two robots 12 inches off of the ground. Hey---anything is possible!!!

Testing the camera mechanism..
We used T-Bot 1.0 to calibrate the camera, and to test the programs this year.
|
What a job!
This year we really wanted to do the programmed mode with the camera.
We had old faithful T-BOT to test. Luckily we had enough space to give free range of motion for the robot. Our
mentor Jason and the programming guru Dana worked a lot to get the tracking system working. GOOD JOB!!

We relied on the forums at Chief Delphi to help us when we got into trouble....Way to go Chief Delphi!!
We got a lot of our technical fixes on Chief Delphi...Everyone had to get a username
and had to post any and all questions....
-
Why do we keep blowing VICTORS?
-
We can't get 20psi!!
-
I like your robot!!!
-
I think something is missing from the schematic...
-
We need a fix for the camera.....
But, we were also able to answer a few questions......
Every time we took two steps
forward, things would happen---such is the case from the e-mail from one of our mentors, Dan Bedore.
---------------------------------------------------------------------
"Last night we discovered that
the problem we had with pneumatics was that the pressure supply was too low, it needs to be at least 20 or 30 PSI, depending
on what valve is used. Actually, setting it too low was my advice, so sorry. See the diagram in the '2007 pneumatics
manual', the pressure has to be at least as high as the little number written next to the valve. This means that the cylinder
will slam open and closed pretty quickly when they're just sitting on the bench for experiments, so use the shortest cylinders
we have so they won't bang into other stuff. In any case, I think the students should build up and experiment with the entire
diagram as shown in the '2007 pneumatics manual'
Eventually, as we solidify the
design, the code will get fancier, but I think we need to hook the whole thing up soon and know everything works and we know
how to use it."
Thanks, See everyone Thursday
