Robot Controller(s)There are two types of controllers: handheld robot controllers and WRB robot controllers. The handheld controller features touch screen command such as attacks, steering and moving.There are 2 known alternatives for these: shadow functions and voice command. It should be noted that the handheld robot controllers are created by the real life computer company HP. On the other hand, WRB controllers are not portable and are used to control WRB robots such as Zeus and Twin Cities. The WRB controllers have joysticks which control the robot's actions and feedback systems which sends the robot's status to the controller. They can control robots manually with the exception of Zeus, which can be controlled either automatically or manually.
