In the paper a method, called tele-autonomous operation for remote guidance
of fast mobile robots has been implemented. With this method, the remote
controlled vehicle follows the general direction prescribed by an operator.
However, if it encounters an obstacle, it autonomously avoids collision
with that obstacle while trying to match the prescribed direction as
closely as possible. This method, allows the operator to steer vehicles
at high speeds and in cluttered environments, even without visual contact.
The value of unmanned vehicles is directly related to the applications
to which it can be successfully applied. This paper will highlight applications,
missions, and capabilities that have been demonstrated on the Lewiatan
platform to date as well as future application and mission considerations.
This platform is equipped with remote control system and surroundings
observation and visualization system. It is assigned for both water and
land - based operations in land-based environment as well as water. In
this paper the advantages of hydrostatic power systems as the power transmission
units for unmanned vehicles have been also presented.
Moreover a terrain mapping method for mobile vehicles with a 2-D laser
rangefinder was described. In the proposed method, an elevation map and
a certainty map are built. Our outdoor mapping experiments demonstrate
that the presented method may be used for remote control of fast unmanned
