There were many other major engineering problems that we had not yet solved by the time we got he call that Double Jeopardy was accepted in February. How would we actuate a large diameter
high pressure ball valve at up to 3,000 PSI? Would our
prototype trigger design work with whatever valve actuation
mechanism we came up with? Could we get it all to work
within the 250 lb weight limit? It was time to finalize our
pretrial preparations and find out.
Getting on the Case
If we were ever served with an
interrogatory requesting that we describe
in detail why the heck we wanted to bring
a cannon to BattleBots, this is how we
would respond under penalty of perjury
under the laws of the United States and
of the state of California.
When we first heard that BattleBots
was back in 2015, we immediately
started designing our own bot to submit.
Watching BattleBots during the Comedy
Central days was what inspired us to
start building robots in the first place,
and it was no exaggeration to say that
competing on BattleBots would fulfill a
Leading up to this point were
countless sketches on pizza place napkins
The secret is out, the slug is out of the barrel, and attorney-client
privilege has been waived — the “punkin chunker” that has made
frequent appearances in Twin Tweaks over the last few years was, in
fact, the prototype for our BattleBots™ contender, Double Jeopardy.
With our coverage of the PVC prototypes in the October 2015 and
December 2015 issues; trigger design in the October 2016 issue; our
initial build and testing of the steel cannon in the December 2016 and
April 2017 issue; and our design of the drive train in the August 2017
issue, we’ve covered a lot of the basics of the design that went into
bringing the first-ever cannon to BattleBots.
