Dorkbot. It's people doing strange things with electricity.
No. Definitely no.
No. Although some do.
We make and tinker and experiment. We do a lot of things.
Some examples: light art, wearable computers, circuit bending, hardware hacking, interactive art, new media, synthesizer invention, insect counting, generative software, etc., etc.
Some of us, believe it or not, don't do anything even remotely robot related.
