I would like to control a robot using 4WD with tank steering using the X-Axis of the Vex RC Transmitter, while at the same time being able to control another motor/servo or two using the Y-Axis. Can this be accomplished using the Vex Controller?
you need a Vex programming kit, but yes you can.
go to RX inputs > 4WD > Tank > then select the two channels…if I get a chance I will try to write the code up
