It seems that your focus is set to improper direction... You're mentioning WiFi too much. Your control can be 100% equal if you'd have Ethernet connection instead of WiFi. Therefore: forget about WiFi, your RasPis are connected together via TCP/IP protocol and this is the only important thing in this context.

I guess that this program controls the robot locally and you'd like to control it now from another RasPi, right ?
If yes, then think about splitting this existing program on two parts - the one for sending commands to the robot (installed on one RasPi) and the other which takes commands from you (installed on another RasPi). What you need to add is to implement/establish a communication path between those two parts now located on two RasPis. For this purpose I'd use sockets.
