As long as the student in the photo is only 42" tall, then it scales out that they can use the wheels.
Alternative hypothesis: The "wheel" will be mounted horizontally. What look like spokes are actually very small airfoils. Spinning very, very fast, the wheel will generate a lot of lift. Presto - instant helicopter! Team 773 is obviously intending to fly over the ramp structure, pluck containers from the opposing team's stacks and place them on the 773 alliance stacks while maintaining a maximum (albeit losing) score for their opponents. Brilliant!
