How to become elite?

[LondonBoy29]

Hi, I am a member of team 1884, one of the only teams in the UK and the only team located in London. This is my second year on the team, and last year I realized that we were a good team with a good robot, but not great. I was just wondering how some teams manage to build these amazing robots. Is it because of engineers? the people on the team? the facilities? the money? great designing using CAD? I am just wondering what peoples thoughts are on how year in and year out some teams have amazing robots.
