Several versions of the robot have been released since 2008. The Nao Academics Edition was developed for universities and laboratories for research and education purposes. It was released to institutions in 2008, and was made publicly available by 2011. Various upgrades to the Nao platform have since been released, including the 2011 Nao Next Gen, the 2014 Nao Evolution and the 2018 Nao⁶

Development history
Aldebaran Robotics was established in 2005 by Bruno Maisonnier, who had previously begun developing the robot under "Project Nao" in 2004.[ Six prototypes of Nao were designed between 2005 and 2007. In March 2008, the first production version of the robot, the Nao RoboCup Edition, was released to the contestants of that year's RoboCup. The Nao Academics Edition was released to universities, educational institutions and research laboratories in late 2008.
In the summer of 2010, Nao made global headlines with a synchronized dance routine at the Shanghai Expo in ]China
