The seal robot was really cute and cool.  If I was rich, I would buy one or just buy a real animal.  The Pedo Bear rob

The robot featured all-terrain tracks and a gripper.  My favorite feature was that the robot would retrack it 

It was cool to see the size of the robots and how they were able to stable themselves so well.  Everything in the video was quite cool except for the song at the end; that was completely pointless.
