One thing that has always impressed me is the Japanese dedication to constant improvement. They keep on striving to improve long after others would have called it quits. A good example is "Hinametetu", the robot builder responsible for the horizontal bar gymnast robot No. 15 Kovacs.
He keeps trying, modifying, adjusting, and retesting his design until he gets it absolutely perfect.
