a Dr. Inferno Jr. toy]
original Dr. Inferno
combat robot, built on a whim, turned out to be a hit. He came
in 3rd place at BotBash
99 and had the dubious honor of being the most spectacularly destroyed
bot at BattleBots
Long Beach 99. I decided to carry on the tradition, but
with a bigger, badder version. Dr. Inferno Jr. competed at BotBash
2000 in Phoenix (see below), and in all 5 seasons of BattleBots.
I didn't have time to finish the doctor for BotBash 2000, but
his finished drivetrain weighed in at exactly 30lb, perfect for
the middleweight class. I slapped on some protective hinges, added
a few parts, and entered him under the name Overpowered Box.
He did great--I was delighted with his performance and his 2nd
Inferno Jr. turned in a pretty good performance at BattleBots
San Francisco on June 10-11. His drivetrain was meaty, but he
shredded a couple of his tires, lost his reciprocating saw attachment
adapter, & blew a motor in the rumble because of a silly hack
I implemented to keep his body level while running on 3 wheels.
So, I did one some tire & motor upgrades for the next event.
Dr. Inferno Jr. won a fight, lost a fight, and put in a good rumble
performance at BattleBots Vegas in November 2000.
he was the feature of two segments on the Movies
For Guys Who Like Movies Judge Dredd airing on the TBS
Superstation, where I took on a few plastic robot toys
and then some fellow lightweight BattleBots.
a few more upgrades, I brought the doctor to BattleBots 3.0 2001
in San Francisco. He took the title this time! Woohoo! He was
seeded only #15 going into this event, and he took down 6 opponents
to win the giant nut.
Doc needed serious repairs & upgrades after getting creamed
in the rumbles in season 3.0, so I entered a heavily-revamped
Dr. Inferno Jr. in BattleBots season 4.0 in November 2001. Major
upgrades included replacing the carbon fiber composite structure
and flaps with very thick polycarbonate sheet, doubling the thickness
of the aluminum frame, switching to NiMh BattlePack batteries,
and ditching the reciprocating saw & configuring with 2 spinner
weapons that I designed with sawblade company SystiMatic. A last-minute
motor "upgrade" failure cost me my first & only
fight, but my great team helped me swap out most of the entire
drivetrain and...Dr. Inferno Jr. won both of the BattleBots season
4.0 lightweight rumbles. Another giant nut!
entered the Dr. in season 5.0, with some drivetrain and electronics
upgrades, as well as a few other minor changes. 5 tough fights
resulted in the Dr.'s 3rd giant nut. Dr. Inferno Jr. is the BattleBots
season 5.0 lightweight champ. 3 giant nuts in the last 3 BattleBots
events. Not too shabby! The Dr. KO'ed fierce spinner Afterburner
(losing his left arm in the process), beat the adorable Tentoumushi
by judges' decision, scraped by in a tough fight against Death
By Monkeys, KO'ed old pal Gamma Raptor, then got darn lucky when
Wedge of Doom blew up half of his drivetrain near the end of the
finals, edging the Dr. ahead by 1 little point in the judges'
Inferno Jr. remote control toys from Hasbro hit the shelves
in August 2002! It's a pretty good likeness of the Dr. and a really
fun to toy play with (or to use as the base of a 1lb antweight
after season 5.0, I undertook some thorough drivetrain upgrades
to make the Doc much much faster and much much more powerful.
He now sports a Dewalt-powered drivetrain from Team
Delta, ready for his next appearance. I upgraded the batteries
with a new set of custom BattlePacks, added tension springs to
the hinged flaps, and changed several cosmetic features.
Like his father, Dr. Inferno Jr. started life as a
Tomy Omnibot toy that I picked up cheap on eBay.
promptly gutting him all of all his computer innards and tearing
off his arms, I began the cordless power tool search to give him
big nasty weapon arms. I ended up with a 12V Sears
Craftsman reciprocating saw and a Chicago Electric 18V
circular saw. For the drivetrain, I picked up 4 Chicago Electric
cordless drills from Harbor Freight. I made motor mounts out of
plexiglass and put together some beefy wheel hubs and bearings.
I needed to decide on a good wheel for this robot, so I bought
a whole bunch and made a wheel
comparison guide to use as a reference. I picked up the
5 Chicago Electric tools from Harbor
Freight, a great source for cheap tools. These aren't
the nicest drills or saws you can get, but if you know you're
going to be hacking them apart as soon as you take them out of
the box, they make a lot of sense. After growing weary of rebuilding
the drivetrain over & over, I finally upgraded to Team Delta's
18V DeWalt drill products. Slick!
first arm weapon I picked up was the reciprocating saw. Its first
modifications were the removal of the saw blade holding mechanism
and finagling a 14.4V battery into the 12V battery slot. I have
several attachments that screw into the end of it: long &
short pokers, long & short bludgeoners, a boxing glove, a
spatula, and a toy robot dog head with a concealed spike for a
tongue. The circular saw underwent some hacking to remove the
blade guards and any other parts associated with safety or handholds.
Next, I had to paint the saw black to match the other arm--couldn't
have one black arm & one bright orange arm. Both of these
arm weapons were originally controlled by a Vantec RDFR22 2-channel
electronic speed controller. Upgrades over the years included
a new Team Delta drivetrain, custom spinner weapons, new materials
choices, and many other changes.
Tool provided nuts, bolts, washers, bearings, & most
of the other odds & ends. Saw blades and custom spinner tri-tip
saws are from SystiMatic.
