knocked off enough of the heads of
the screws that held the latter’s wedge
on, and could deliver a killing blow.
It then faced Project Darkness
again, this time getting the better of
it in another brutal fight. Its luck
finally ran out, however, in the finals
when it stopped working shortly into
the fight, giving Speed Wedge 3 an
The 12 lb Hobbyweights were
once one of the most popular weight
classes, but there has been a decline
in numbers the last couple of years.
This time, there were only three bots
competing, and only two of them
were serious combat bots. This was
Isotelus Rex’s first appearance at
Franklin and the first event with its
new wedge and brushless drive.
The other serious competitor was
Disko. This bot normally competes as
a 15-lber but with a little armor
removed can compete as a
Hobbyweight. The third bot was Plan
X..ish — a cardboard and duct tape
tribute to the heavyweight, Plan X
that took part in last year’s
BattleBots™ TV series.
Both Isotelus Rex and Disko easily
dealt with Plan X…ish — both times
reducing it to tatters — but the fight
between them was more challenging.
The brushless drive in both bots
worked well, but the wedge on
Isotelus Rex was a failure. It failed to
reliably get under its opponent and
then tended to jam in either the up or
Isotelus Rex was treated like a
chew toy by Disko, taking a lot of big
hits and eventually losing drive on one
side, but lasting the full three minutes,
then losing by an easy judge’s
decision making Disko the winner of
the round robin.
The heaviest full combat class at
Franklin are the 30 lb Featherweights.
Five robots competed. There was one
horizontal drum bot, Drum Thing Else;
our new horizontal blade spinner,
Glasgow Kiss; two thwack bots,
Gracious Pipefessionalism and Spur;
and reigning Motorama and Franklin
Institute Champion full body spinner,
This was the first event for
Glasgow Kiss and its first fight was
against Drum Thing Else. Glasgow Kiss
has the same experimental brushless
drive that is in Isotelus Rex, but it
proved less effective in the bigger bot.
There was plenty of speed and power,
but with little or no braking in neutral
and with a lot of pulling from the
weapon drive axle on the floor, it made
the blade spinner tough to drive.
The drum bot, however, never
really got spun up and an early hit by
the blade spinner took off one of its
wheels. Even with the biggest hits
being against the arena wall, Glasgow
Kiss succeeded in knocking out the
drive on the other side forcing Drum
Thing Else to tap out.
Spur beat Gracious
Pipefessionalism, and was then beaten
by Triggo. This set up the first
Glasgow Kiss vs. Triggo match. The
drivers had agreed to spin in opposite
directions for this fight, to save going
tooth against tooth for the likely final.
Triggo spins at about 2,000 RPM,
while the blade on Glasgow Kiss spins
at about 4,000 RPM. So, if they spin
in opposite directions, they tend to
mesh like gears with the effective net
hit being at about 2,000 RPM in the
favor of Glasgow Kiss.
The first fight went to Triggo with
the full body spinner getting the
better of the hits and then knocking
out the drive on one side of Glasgow
Kiss to win by a tap out.
The blade spinner quickly
defeated Gracious Pipefessionalism in
the loser’s brackets by removing both
its wheels, to earn a place in the finals
This time, the bots would be
spinning in the same direction,
meaning that the weapons would
meet effectively at 6,000 RPM. This
made a huge difference.
With Glasgow Kiss spun up to
maximum for the first time (the bot
was easier to drive with the blade
spinning slower) and the matched
