Output not updated often enough error

[Chiller]

In your robotInit instead of:

Joystick left = new Joystick(1);
Joystick right = new Joystick(2);
        
RobotDrive robot = new RobotDrive(1,2,3,4);

Replace it with:

left = new Joystick(1);
right = new Joystick(2);
        
robot = new RobotDrive(1,2,3,4);

You already created the object above so right here you just have to initialize it! Your IDE should've given you an error...
