Willow Garage was a robotics research lab and technology incubator devoted to developing hardware and open source software for personal robotics applications. The company was best known for its open source software suite Robot Operating System (ROS), which rapidly become a common, standard tool among robotics researchers upon its initial release in 2010. It was begun in late 2006 by Scott Hassan, who had worked with Larry Page and Sergey Brin to develop the technology that became the Google Search engine. Steve Cousins was the president and CEO. Willow Garage was located in Menlo Park, California.

Clearpath Robotics, Inc. was founded in 2009 by a group of four University of Waterloo graduates, and remains headquartered in Waterloo Region, Canada. The original goal of Clearpath was to streamline field robotics research for universities and private corporations, but the company has since expanded and is now also manufacturing and selling the OTTO line of self-driving vehicles for industrial environments.
