We've managed to get the robot moving without the use of encoders, but as suspected, the wheels do not turn at the same rate when turning due to the different ages of the motor controllers and the wheels initial starting positions. Now we just need to figure out how to implement the encoders to make the wheels turn simultaneously. We are not particularly worried about making the robot make an angled turn or pivot on a wheel at this moment, so I believe it would be alright to use only one PID since two wheels would be set to the setpoint and the other two would be the same but opposite.
I still need help setting up PID in labVIEW. I believe the MA3 uses analog signal, but I don't know how to set that up in labVIEW.
Thanks for the help!
