Have you thought of something along the lines of the old "Potato gun" idea ??
you could use a combustion chamber that is fueled by a main tank and ignited
by a charge ~ something like a starter on a gas grill.
(see attached sketch)
You could fill a small chamber with a modest amount of fluid ~ like lighter
fluid ~ from a main tank ~ the grapple could be pulled into place by the
winch and mechanically slid into the chamber ~ then launched ~ and then
retrieved by the winch ~ to be launched again and again until the fuel supply
is gone ~ but that too could be refueled by the bot by when it indicates a
low level it could return to a fueling station.
Just a thought
