The major issue you need to address is what data rate do you need to control the robot.
2 way radios are very slow in sending data because they are 1/2 duplex, ie you can send or receive
but not both at the same time.
Ensuring that what you send actually gets to the other end is a complex process involving sending then receiving
then sending again.
The actual data thruput can be as low as 100 bps , even if the radios can go faster.
With unmodified radios you are limited to around 1200 bps .
Going faster needs modifications to the radios which normally you cant do unless you have the circuits of the radios.
Id be looking at using broadband wireless using the cellular radio system to get more speed and reliability.
