===2007===
ROS was started by borrowing the best practices from many early open source robotic software frameworks including ''switchyard'' by the [[Stanford Artificial Intelligence Laboratory]] in support of the Stanford AI Robot STAIR (STanford AI Robot) project.<ref>{{cite web|url=http://stair.stanford.edu/|title=STAIR|website=stair.Stanford.edu|access-date=12 December 2017}}</ref><ref>{{citation |title=STAIR: Hardware and Software Architecture |first1=Morgan |last1=Quigley |first2=Eric |last2=Berger |first3=Andrew Y. |last3=Ng |author3-link=Andrew Ng |year=2007 |url=http://www.aaai.org/Papers/Workshops/2007/WS-07-15/WS07-15-008.pdf |publisher=AAAI 2007 Robotics Workshop}}</ref>
In January of 2007 Willow Garage hired their first employees: Jonathan Stark, Melonee Wise, Curt Meyers, and John Hsu.
By the seventh of November, 2007, the first commit of ROS code was made to SourceForge<ref>{{cite web|url=https://sourceforge.net/p/ros/code/10/log/?path=|title=Repository: code|website=Sourceforge.net|access-date=12 December 2017}}</ref>
