Torque vs wheels

[zabuza™]

I am using 2 wheels, 1ball caster. If you are calculating starting torque of a robot so that it moves, would you add torque from both the wheels to generate movement or just one wheel?

Both wheels.
Have you found the Motor calculator in the SoR tutorials? This is one of the boxes to fill in.
