I'm looking for a wireless control system that does not require a computer. We're going to be building a basic bot that the public can operate during halftimes at sporting events, and I don't want to risk a catastrophe with a laptop.

In my brief searching, I've seen that I can utilize a PS3 controller or XBOX 360 controller with a simple Bluetooth or USB dongle, but my understanding is that the range wouldn't be sufficient - I'm hoping for football halftime so maybe about 50 yards? (sideline to midfield)

Anyone have any input they could help us out with?

Thanks in advance -
