This video introduces TurtleBot 2, which was shown this past weekend at ROSCon 2012. TurtleBot 2, built around an iClebo Kobuki from Korean firm Yujin Robot, improves upon the original from Willow Garage. (Note that Sam Park, Executive Vice President of Yujin Robot, recently joined Brian Gerkey, Director of Open Source Development at Willow Garage, on the board of directors for the Open Source Robotics Foundation.)
