Daffodil Version 1
Report |
Daffodil is a 12 pound "concept
bot" -- the concept is to make a bot that is as much drum
as feasible. Here are the specs for version 1 of the bot,
which fought at NERC's IHXRC and SECR's Farm Fight.
Originally conceived as a 220lb BattleBot Heavyweight, a
12 lb bot proved a saner thing to start with.

| Daffoil was built for
the NERC IHXRC competition in Chicago,
September 2001. Not many pictures were taken
of its build and we don't have any of the
competition itself. At left is the drive
train. You can also see the plates which hold
bearings which are used as rollers. The drum
spun on those rollers, and made a horrific
racket doing so!
Unfortunately, Daffodil didn't do very well
at IHXRC, mainly because of terrible problems
with radio control. Daffy won its first match
and was barely controllable some of the time,
but then lost its subsequent two matches
simply because it would not respond at all to
radio commands, and would only move randomly
and sporadically.
IHXRC result: 1 Win, 2 Losses

| Daffy verision 1.1
was the same as version 1 except the entire
electronics setup was replaced in an effort to
cure the gremlins that sidetracked it at IHXRC.
This effort was successful, and Daffy competed
at the SECR Farm Fight in Florida, January
2002. Overall, FF was a much more successful
event, since I could communicate with the bot.
However, there were a bunch of other
problems that crept up. During Daffy's first
fight, one of the gears in the left drive
motor broke and caused that wheel to move
erratically throughout the rest of the
competition. Additionally, the hinge holding
the drum motor came apart, and the gearbox on
the right drive motor came out of its mount!
Daffy won the fight (barely) anyway, and the
latter two problems were repaired. The broken
gear caused problems throughout, though.
Nevertheless, Daffy made it to the finals
where it lost (for the second time that day)
29-16 to the NERC legend bot 911. As
the picture at left shows, 911 really pounded
on Daffodil in the two fights. But the
apparently vulnerable exposed wheels are
actually attached pretty well and stood up to
the punishment.
911 is now Daffodil's nemesis.
Between the pounding, and a neverending
desire to tinker, Daffodil needed to be
rebuilt.
Farm Fight result: 3 Wins, 2 Losses.
Second Place.
