Originally, Coroner was built as a
horizontal bar spinner, very similar in design to the others in Team
Hardcore's roster. This is a 60 pound lightweight category bot.
We could have continued development on this one, and most certainly
could have reached a point where it would have been a factor in the
weight class. But we ended up with an opportunity to try something
different, and so we did. The bar spinner version of this was given to
Team Tiki, and they continue to work with it currently.
This full shell spinner was
originally competed by RDC, the Robotic Death Company. It was
originally called Rambyte, and was a fairly effective lightweight. But
the shell was actually kind of heavy (just over 30 pounds) and with the
motor and battery technology of its era, they could never quite get the
dominance with this that they saw with their heavyweight Megabyte. At
some point they decided to retire from robot fighting, and this was
just sitting on a shelf. I asked about continuing to develop it, and we
were given the chance to give it a shot!
One of the key places where
technology has improved is in brushless motors. The short mag on the
right (same as the A28-150 Ampflow) is just under 4 pounds, and has 3
horsepower. The brushless on the left (Great Planes Rimfire 65cc
Electric) is just over 4 pounds and 10 horsepower!
Almost all of the internal physical structure is changed very little. Most of the upgrades were to electronics.
The brushless fit easily as far as height went, but it was just
slightly wider than the mag it replaced. I had to narrow the rails
slightly to get it to fit.
We did have some repairs needed for the titanium shell. The top of the
shell had been ever so slightly stretched, and it was near impossible
to get the shell to spin level. Cutting out the top and rewelding it
looked like an option, but we ended up taking a simpler (and much
cheaper!) route. A piece of half inch thick aluminum was cut to match,
and simply bolted into place. The extra rigidity across the top fixed
all the issues, and even after several brutal matches it still spins
The only major renovation to the shell was in the bottom reinforcing
ring. Originally this ring was only 1/8 inch, and it is now 1/4 inch.
The ring was damaged in a match against Touro Light so we upgraded it
for more strength.
