Tying button to key stroke

It’s more for a toy I’m building. I’m trying to put together spare parts I have and build a remote operated vehicle with a camera on the front and have all the controls in Ignition. I can do it with a joystick but then that’s another interface I would have to build and carry. I was trying to make it just two pieces, my laptop and the bot. I have an Ethernet radio and an ADAM Ethernet I/O module I was gonna use for the control of the vehicle.
