Essential difficulties in the operation processes of a single-bucket excavators is the fact that they are multi-functional machines. They can be fitted out with a range of various working features. Hence, elaborate automatic control system is being indispensable. It makes possible, the flexible co-operation with the operator in carrying out different technological tasks. The structure of this system ought to make possible an easy adaptation of the single-bucket excavator for carrying out specific tasks (without wasting a lot of machines' working time). This also applies to work in hazardous conditions for the operator, or completing the earth-moving operations with great precision. In this paper, a solution of such a system is discussed, backed by computer-aided controls in connection with remote control and laser control systems for fixing the position of the machine with improved precision.
