Devilcat II

final.jpg

Intro

Devilcat II is a revisit to my second robot, Devilcat. It's similar in design but benefits from a lot more experience. It's designed, ultimately, for self-contained implementations of current indoor SLAM algorithms.

Mechanical

Devilcat II's structure is made from smoke-gray lexan.

There are two drive wheels and two omni-wheel casters on springs. Unlike traditional casters, omni-wheels are stateless and thus less prone to acting weird.

Gratuitous machining. You may waste a whole saturday doing it, but compared to all those losers who build robots with parts from the plumbing section at Home Depot, there is something really satisfying about making the *exact* part you want.

Electrical

Devilcat II is powered by two 7.2V 4.2Ah NiMH high-performance RC car battery packs. These things are capable of really scary amps.

You might recognize these Nano-ITX components from the scrapped logo.

Fate

Devilcat II is still a work-in-progress at this point. Mostly, I've suspended development on it because (1) I decided to re-tool the frame for better motors because the ones in it now aren't that great, and (2) I'm not really sure what sensors to put on it.
