With all these companies listed I'm surprised Willow Garage didn't join up with Google; given that the founder was a googler.

In effect, they did. Willow Garage was restructured into Redwood Robotics. Google purchased Redwood Robotics. There are certainly lots of messy details, but the key projects (ROS & OpenCV) and the engineers from Willow Garage are now at Google.
