Future trends in design of construction and agricultural machines

New trends in design of construction and agricultural machines are apparent mainly in aims that they should achieve e.g. economic transport, more efficient work technologies, environmental protection etc. The controlling process of building or agricultural technologies is often very similar. This operational control includes e.g. laser methods that operate construction and agricultural machines by means of total station; Global Position System (GPS) with a mobile map utilization that controls construction and agricultural machines etc. The mutual combination of these systems can be seen as well. Stability analysis of the system implementation is to be done in Czech Republic. The main reason for the analyses is eventual wearing out of firm’s machinery. The paper describes the mathematical model of laser control and dozer’s work technology with the utilization of GPS and laser.
