Need Assistance with making autonmous work.

Just to be sure, do you know if the switches work? They should have a connection between signal and ground on a DIO port.

They work 100% in teleop. Also, is there a way to make the robot wait until the piston is done opening before it starts with the rest of auto?

You'll need some sort of sensor to detect when that happens. If your pistons have ferromagnetic plates, you can place magnetic switches on the outside of the pistons to detect when the piston is "done". These switches are usually provided by Bimba with the FIRST choice cylinders, or can be purchased easily enough. If your pistions are non-magnetic, a limit switch is your best bet. These can be triggered mechanically or through magnetism, or even optically. Figuring out what style of limit switch you need is very dependent on your application. If you can't think of how to place a limit switch on your device, I suggest going to google images and searching for "limit switch". Look at the pictures until something looks like it could work, or 100 pictures, whichever comes first.

FWIW, the 3946 robot has three distinctive styles of limit switch this year; two optical, six push-button, and four lever arm with roller.

Two options:

1) Put a magnetic sensor on the piston. Then you can tell when it has moved to the desired location.

2) Put a time delay, and wait 1 second, or however long it takes the piston to move.
