There have been a select few robots that have satisfied the following criteria:
- Won all of their events, including the World Championship
- Were either the #1 alliance captain or first overall pick at all of their events
While I'm not saying this list is contains, objectively, the most effective robots ever, it is clear that they were dominant. And to someone like me who heavily values event wins and high seedings over more "soft" achievements like being highly effective in a match or two here or there, these robots have most effectively fulfilled the game challenge.
1678 in 2015
254 in 2014 (Waterloo #2 alliance captain; probably should have been first overall pick)
254 in 2011 (Galileo #2 alliance captain; probably should have been first overall pick)
67 in 2009
1114 in 2008 (Midwest #3 alliance captain; probably was or should have been first overall pick)
Honorable Mentions:
118 in 2015 (#2 alliance captain at Dallas; #1 alliance captain 148 chose 987 and lost to 118 in the finals)
469 in 2010 (soooooooooo close!)
