“Mega-bots” creators constructed this massive concept robot in hopes of building a league of combat bots for spectators. Their fighting robots would be piloted by teams of drivers, and use massive hand-made paint-balls to knock armor and other pieces off of their opponents”. They use high powered “potato cannons” that no one has ever seen. They use a giant paintball as weapons. Also they hope to fight other robots and created an large league.

This relates to engineering because it took lots of engineers to make these robots and will take many more to maintain and build more.
