I have actually designed a computer vision platform (but for use at ETH) before I designed the original Pixhawk and it finally seems its time to bring that expertise to the open source space. Here is how the platform from 2010 looked like. Note the original "pxIMU" which predates the Pixhawk design.
I'm looking for community feedback both in terms of requirements as well as in terms of mechanical frames that you think would be a good starting point. My goal is to design something that serves as a good development platform. However, it should also be very close to a market-ready commercial reference design. Pixhawk did hit both marks.
