Comments and General Information:
Fashizzle is my latest robot creation. On May 25th, 2003 it earned me
one win and two losses for PDXBot.03.
In its first matchup it lost to a robot named Chip, made by Dan
Gates, which I believe is a modified Mark
III kit. I blame the loss on poor positioning on my part. For some
reason I wanted to start a push-off with a robot I designed to avoid push-offs.
For the second
match, I had to, ironically, compete against my dad's robot that last
year earned its sole victory against my robot Giskard. Lil' Fashizzle,
after some mild sensor trouble, avenged my defeat and earned me, ironically,
my sole victory for this year's tournament.
In my final
match I faced LandShark,
a fast robot that Lil' Fashizzle had lil' chance of escaping. It lost
two of three rounds, and thus the match. LandShark ended up taking 3rd
place in the contest.
its slow speed and little torque were its fatal flaws. Still, I'm happy
enough with it that it will earn the distinction of being the first robot
I won't recycle for future robot parts. Afterall, it did earn my goal
of a single victory. It was named after the urban slang term meaning "for
I plan on
building Fashizzle 2.0 based upon what I learned from this robot. Expect
better sensors, faster motors, and a sleeker design.

approx. $210 combined part worth (including batteries and charger)
An OOPic, and standard board, serves as the robot's microcontroller and electronic base.
Four front sensors provide a wide-angle range of vision.
There are only two bolts/nuts in the robot, which are used to hold the board onto the frame. The rest was assembled with double-sided and electrical tape.
Three switches serve as tilt/edge detectors. Their reaction time is very quick, but unfortunately requires the robot move slightly off the edge of the ring, increasing the risk of getting knocked out.
The front sensors are low to the ground, taking away some of the low to the ground robots' advantage.
The frame is made out of copper.
