The BUILD: WIDGETS Robotics Challenge requires teams to design a LEGO robot that will help them gather elements, build widgets, and move them to their scoring locations. There are a total of 18 game elements available for each team to use to assemble widgets. A widget is defined as a combination of exactly 2, 3, 4, or 5 elements that are connected together, but not touching a robot. Game play includes a 30-second autonomous period and a 90-second driver-controlled period, where team members use Bluetooth devices to operate their robot as they complete a list of tasks to earn points. We’ve done the math, and there are a total of 12,597 unique combinations of game elements that teams might utilize as they take on the challenge.
