LOLrioKart at MITERS

What originally started as a whimsical attempt to strap a set of large nickel cadmium batteries, discovered in a dusty back room, to something – anything – has turned into a full-fledged ambitious engineering project. LOLrioKart has become, for better or worse, my most well-known work, and something of a campus icon.

It is also a constantly changing experiment and being upgraded and permuted whenever I think of something else to add. It’s the test platform for all of my electric vehicle controller development. The “vehicle” possesses features not found on the average small go-kart, such as dual front disk brakes and a custom-designed and fabricated rear differential. The motor controller is a fully custom work and practically a project in its own right. The latest controller iteration adds regenerative braking and non-contactor reverse ability to the electric drive (i.e. a 4-quadrant drive).

Then, of course, there is the 4-channel surround sound system with subwoofer. That makes it all worthwhile.
