This would be a drive program for a Swerve drive, or maybe a Maccanum drive.
My team has never done this, but I would LOVE to see a good chassis that was driven relative to the field, not the robot. It would be very easy to drive, and could be a fast and reliable scorer, regardless of the game.

That's called "field-centric" control, and is pretty common with swerve drives. I know 1717 did this when they were around, 16 does both that and "robot-centric" by pressing a button to switch (or used to, anyway). It is a very useful feature, especially for new drivers. Mecanum wheels or an omni-wheel H-drive could be used to start this.
Writing some kind of program for a motor to hold an arm up would be tricky, but a good software project. You would only need a motor, gearbox, encoder, and some kind of off-center mass.
