What we need to do for this is have a command group that will perform multiple functionalities.

1. Be able to move the forks to the correct height
2. Be able to pick up crates (this may require to move a bit forward or back and fire the solenoid then move up a bit
3. be able to put a crate down on a stack then pick them up
4. be able to put crate down, rotate around the stack (later will push forward into auto zone)
