Power Up is the name of the 2018 FIRST Robotics Competition challenge. Two alliances of three robots each compete to place milk crates, or "power cubes", on large balancing scales to tip the scale and gain ownership. Alliances can also trade power cubes for power ups, giving them a temporary advantage in a match. At the end of the match, robots can climb the tower attached to the center balancing scale using a rung attached to the tower. More information can be found on Wikipedia.
