amphibious off-road drive system, 09th November
Screw-propelled vehicles are nothing new, in fact they've
been around for decades. But they never really took off
due to the fact they are normally slow, inefficient, and
unable to travel over land with out tearing it up. However
they did have some advantages over their wheeled or tracked
counterparts, the most important of which is the fact
they can haul themselves through mud and bogs with relative
ease, and when the land ends they can be driven over open
A conventional screw-propelled
Tesh-Drive on water
Russian inventor Alexey Burdin has come up with
a screw-type propulsion system called 'Tesh-Drive' which
features all the benefits of screw-propulsion and less
of the negatives, rekindling the hope that screw-propelled
vehicles may one day become more popular for traversing
difficult swampy terrain.
The name 'Tesh-Drive' was derived from Alexey's nickname
for the concept which was 'transformable worms', the reason
why he used the term transformable is because the rotating
screws can be altered to function on hard ground (including
roads), soft wet ground, or water. To accomplish this
the Tesh-Drive features a strong inflatable rubber tube
which wraps around the screw drive.
When the tubing is inflated it forms a wheeling body enabling
the vehicle to travel on hard surfaces at speeds similar
to ordinary vehicles. When the Tesh-Drive vehicle is being
used on either soft ground or water the air is let out
of the tube, therefore allowing the metal ridge of the
screw to bite into the earth, or cut through the water,
and propel the vehicle forward.
Currently Alexey and his team are developing the Tesh-Drive
concept further with the help of a large scale remote-control
prototype. They are using the prototype to develop the
concept further and understand exactly how the system
works and identify any issues or problems.
Alexey's ultimate goal is to produce a perfected Tesh-Drive
system and control interface which can be used on everything
from remote-control models and autonomous off-road vehicles,
to full-size amphibious transport and military vehicles
capable of carrying people and cargo over the most inhospitable
muddy, swampy terrain.
Obviously due to the complicated nature of the Tesh-Drive
concept it's fairly difficult to explain in one short
article so here's a couple videos showing the prototype
during initial testing. Or if you want the cold hard facts
