a successful sponsorhip of high-performance motors in my 12-pound
Hell on Wheels,
I joined ThinGap
as an Applications Engineer, where I designed motors, fabrication
equipment, and more. I wanted to showcase ThinGap's small-but-powerful
motors in a 120-pound robot. Around the same time, NPC
Robotics, who was the powerhouse in adapting their extensive
wheelchair experience into larger motors/gearboxes/wheels for
the bigger bots, was looking to develop some products for the
smaller bots. Around a sturdy NPC-designed gearbox & a hardened
version of ThinGap's smallest brush motor was born a compact motor/gearbox/wheel
product, only 1.5 inches tall. For a few years, I'd been dreaming
up a robot that would have 2 major weapons instead of just 1.
With the volume & weight savings of this compact drivetrain,
I was able to realize my concept of a robot with not only a large
spinning disk but also a powerful lifter--Disko Inferno was born.
Its weapon combination allowed for self-righting; bringing the
disk down to the floor level when fighting low bots; & flipping
other bots onto the spinner's top teeth, garbage disposer-style.
I entered Disko Inferno in RoboGames 2005, where Disko Inferno
Disko Inferno featured 4 small ThinGap brush motors
& NPC Gearboxes & Whyachi
wheels for drive. The lifter & spinner weapons were each
driven by a large ThinGap motor that I had designed for a Navy
Seals extreme power drill. The spinner weighed 25 pounds (very
heavy for a 120-pound robot!) & featured 4 hardened tool steel
