I did this last year. It worked, but I couldn't get used to the way the joystick felt in my hand. I had a hard time moving the stick along the diagonal when going straight forward and reverse.

You would also need a rotary pot to control the rotation of the bot.
I used the joystick thumb wheel for this (NOT the trim wheel!). Again, it worked, but I didn't like it because it didn't self center when released.
