Is that alone legal for 2011?

I don't see anything that would make it illegal.

Furthermore - the custom app, upon receiving input over usb, sends a tcp packet to the robot to perform an action.
still legal for 2011?"

As long as it sends it over the competition network, I see no reason it wouldn't be.
