That appears to be a Fanuc robot, I used to program them. They aren't "run" by an individual. A path is "taught" and the robot stores coordinates to remember the path. It will run the same path everytime, usually to within a few thousandths of an inch.
It does to appear to be a an extremely powerful one though. Most of the ones I worked with had a max load of 300 lbs or so and that was at only an couple of inches from the wrist's axis of revolution and speeds less than 1500 mm/inch (slow). A man the size of that guy whipping around and changing directions so quickly is exerting a tremendous amount of force on the drive line of that go-bot!!!
Cool video though.
