Robots FTW! One of the high school students I interviewed for my admission to my alma mater this year has been really involved in this crazy robotics competition that is held every year by US First.
Teams of students design robots for gameplay, which involves picking up these multi-colored balls and shooting them at designated targets. Robots are big - human-sized! - and the arena is like a small stadium, thronged with people.
I kind of want to go watch it.
