Arcade drive refers to the style of control (i.e. one joystick controls linear and turning movements on the robot). The options above describe the configuration of the wheels themselves, not necessarily the control scheme. Though it can be confusing because dual joystick drive control is referred to as ātank driveā while there is also a tank drive wheel configuration.
More or less just ready to compete. Like, Iām done because I can solidly compete now (that was an an example). But yeah I guess the subsystems would be a good descriptor.
