// Main Task
//
// The following is the main code for the tele-op robot operation Customize as appropriate for
// your specific robot
//
// Game controller / joystick information is sent periodically (about every 50 milliseconds) from
// the FMS (Field Management System) to the robot Most tele-op programs will follow the following
// logic:
// 1 Loop forever repeating the following actions:
// 2 Get the latest game controller / joystick settings that have been received from the PC
// 3 Perform appropriate actions based on the joystick + buttons settings This is usually a
// simple action:
// * Joystick values are usually directly translated into power levels for a motor or
// position of a servo
// * Buttons are usually used to start/stop a motor or cause a servo to move to a specific
// position
// 4 Repeat the loop
//
// Your program needs to continuously loop because you need to continuously respond to changes in
// the game controller settings
//
// At the end of the tele-op period the FMS will autonmatically abort (stop) execution of the program
