Unattended operation system for bulldozer

Abstract

Abstract PURPOSE:To improve efficiency in execution of work by providing an automatic tracking three dimensional survey system, an unattended monitoring system for information making, a bulldozer operation control system and a safety- monitoring system. CONSTITUTION:An automatic tracking three dimensional survey system A composed of a light-wave range finder 3 and an image processor 4 makes automatically surveys for automatic tracking to machine positions resulting from inputting of terrain information and moving of a robot bulldozer C and for information about position coordinate. An unattended monitoring system for information making B works for selection of optimum work pattern and for processing of output control information and, at the same time, works for selection of optimum operation pattern for the bulldozer C and for giving instructions thereto. Thereby the bulldozer C works with recognitions of its position and attitude under a system capable of doing automatic operation according to each of operational informations. A safety-monitoring system D controls the automatic operation with confirmations made to scope of operation, existence of obstructions and attitude of the bulldozer C.
