The 2016 FRC challenge is called "FIRST Stronghold" . FIRST Stronghold is played by two competing Alliances on a 27 x 54 foot field.-
An Alliance consists of three robots. They compete to score points by crossing elements of their opponents’ outer works, scoring boulders in their opponents’ tower goals, and surrounding and scaling their opponents’ tower itself in designated locations during a 2 minute and 15 second match.-
The match begins with a 15-second Autonomous Period. During this Autonomous Period, robots attempt to cross opposing defenses and score in the opposing tower.-
For the rest of the match, drivers control robots and try to maximize their Alliance score by scoring boulders in their opponents’ tower goals.
