Consider the swamp. And I mean swamp in the pejorative
sense: this is not a wetland. The enemy swamp. One
cannot walk through it because it gets deep and there are
plants. One cannot boat through it because it is shallow
and there are plants. One could fly over it, but it is
to poke anything with a long stick from a plane. A
low flying dirigible though...
Flying is out. One could use a fanboat. But they are loud
and you cannot hear the birds, and also they spatter mud
on your linen suit.
The slug treads are like tank treads but instead of metal
bits there is a gooey asphalt-like substance. This
substance conforms to the substrate, allowing traction. It
is hydrophobic and so does not wash away, and can be
reclaimed. It allows the vehicle so equipped to roll across
vegetated shallow water.
Some gooey tread might remain lodges in twigs / branches
of vegetation so traversed. An onboard tank allows

||Another option for navigating a swamp is a hovercraft.
However, if you dislike the noise of a fanboat, you will
probably dislike the noise of a hovercraft even more.
||Your solution may have a problem in that if the tread
material repels water, then how is it going to push water in
the desired direction when the tread rotates?
||/then how is it going to push water in the desired
||It repels and floats on water, and there is a large and
irregular water / slug tread interface with frictional
effects between them. Open water would be least
good. An irregular water surface with vegetation
would be best. Muddy goop / quicksand would be ok.
||Slipperiness aside. The problem is weight spread . Even a
tank will spin if the ground doesn't support the weight.
||Don't slugs use peristalsis? which like gapping one footing to
the next. Again, though, if the marsh/environment can't
support the weight your not going anywhere.
||I think I'll stick with screw drive: [link]
