Realistically, if you're building a Mecanum Drive you shouldn't really ever need to push someone because you can drive around them. In the situation that you were being pushed, then you would drive around them. Your increased mobility is what you would use instead of the ability to push.

As far as controlling it goes, (I believe someone mentioned the difficulties controlling a mecanum drive above) You can use a combination of 2 joysticks, one for X/Y travel and the other for rotation, or a 3 axis joystick where you have the conventional X and Y and then also have a twisting Z axis.

Btw, you guys are pretty close to 816, if you ever need anything let us know.
