We have one piston on our robot.
Will putting the tanks in parallel provide more force?

And any other facts would be great.
Thanks.

OK, the simple answer is ... it depends.
It depends on what is the controlling orifice (what has the most restriction or lowest CV) as to whether series or parallel is better. squirrels' answer assumes that the regulator is the controlling orifice, which is generally not true. Usually the valve has the controlling orifice.
Changing the path at the controlling orifice (IE splitting the flow path and having it run through 2 valves) will garner you the biggest bang for the buck.

I believe that the regulators are a 'bleed' type which means that when the output overpressurizes (goes over the setpoint pressure of the diaphram) the regulator bleeds off the excess pressure through a pressure relief vent. This would mean that if both regulators weren't set
EXACTLY at the same pressure (no easy feat) then one would continue to supply air while the other would be venting it, and that would tax your on-board compressor.
