Add Disabled/Teleoperation/Autonmous Buttons

[VladimirKupryukhin]

Context

If you have ever been in First Robotics (FRC), you would know that the the base station has three states: disabled, teleop, and auto. These are the three different modes the rover can be in.

• DISABLED: The rover cannot be controlled, but we are connected to it.
• TELEOPERATED: The rover can be controlled manually through the use of gamepad controllers
• AUTONOMOUS: The rover will execute its autonomous regime

How to Implement

Make these three buttons very easy to see on the user interface. Make these buttons send a ROS topic; perhaps just one topic with a different piece of data for each mode? The code on the rover can then hold these states to determine the current state of the rover (perhaps through the use of the Robot Interface?). Making a hotkey (perhaps "space bar") for the disabled button could be a safety feature for quick access. Whoever chooses this is quite free in the creative/design process.
