Andrzej Typiak Remote Controlled Vehicle with Hydrostatic Driving System

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 ground vehicles.
