RoboMaster is a robotics competition on projectile combat. Robots fire projectiles and attempt to hit pressure sensors installed on the opponent's robots & structures. 

The robots have classes that differentiate their abilities & limitations. Depending on its class, a robot may be able to fire larger projectiles that does more damage, or smaller projectiles at a higher rate.

Every class of robot (except the sentry) may have up to 1 driver. Drivers see the field from a camera on the robot and control the robots similar to a traditional first person shooter game.
