My name is Michael Raphael and I am a SFX recordist for Film and Games. I have been working on a Small Motors sound library for my company http://rabbitearsaudio.com . I reached out to Matt Giffin at Maker Bot Industries because I wanted a real robot to make robot sounds for the library. Matt was incredibly enthusiastic and hooked me up with Charles Pax, who programmed the Maker Bot to perform a variety of actions.

I m excited to share the fruits of our labor on Thingiverse.

Each action of the bot was recorded from a couple of different perspectives inside the bot. Within the zip file you will find multiple files of the same sounds recorded with different microphones.

You can find other motor based sounds here:
