Founded in 2005 by French entrepreneur Bruno Maisonnier, Aldebaran Robotics became one of the world's leading companies trying to commercialize humanoid robotics. Aldebaran opened offices in France, China, and the United States. In 2008, the company launched the Nao robot, which has become an internationally adopted platform used in education and research in more than 600 universities, labs, and schools. Maisonnier's vision was that robotic companions to assist humans would no longer be science fiction but a realistic answer to the demands of an aging society. Aldebaran set out to explore humanoid robots in areas such as autistic child therapy, human-robot interaction, and personal robotics, employing more than 250 people, including 50 percent in R&D. In 2014, Aldebaran and SoftBank introduced a new, larger humanoid called Pepper, designed as a companion and helper robot. SoftBank acquired a majority stake in Aldebaran in 2015. In April 2022, United Robotics Group, in Bochum, Germany, acquired French subsidiary SoftBank Robotics Europe, headquartered in Paris. SoftBank Robotics Europe reverted to its former name of Aldebaran.
