Rather than build their creation from scratch, they built off of the Robot Operating System, an open source OS that, in the words of one engineer, 'allowed only a few engineers to write an entire system and receive our first check for service in only a few months.' With ROS robots starting to appear everywhere, including the International Space Station, it looks like open source may be making huge strides in this area.
