Hooking up a commercial board to provide servo stabilization is not the
hard part (purchase board, plug servo into board, plug board into
receiver). The hard part is getting a barrel/marker assembly that
weighs more than a couple pounds to respond quickly and smoothly. In
the video shown, the barrel assembly is lightweight plastic and it's
momentum can easily be overcome by a standard servo. Even still, you
can see a definite lag time between the vehicle movement and the
corresponding gun movement.
Increase the weight being thrown around to a couple of pounds, with a
moment arm of up to 2 feet and the control mechanism must work much
harder, resulting in a harder feedback problem. Throw in actual dynamic
forces from driving around on an un-even surface with a heavy vehicle
and things get even harder.
