Willow Garage's ROS initiative is celebrating it's 3rd birthday, and what it has been able to accomplish in an extremely short period of time is pretty astounding. There are 50 ROS public repositories contributing open-source libraries and tools for ROS, more than 1,600 public ROS packages, and over 50 different types of robots using ROS. The ROS community is huge and continues to grow dynamically
By the way, the humanoid robot shown at the 1:54 mark in the video belongs to Taylor Veltrop, one of our friends and fellow robot fans here in Japan.
