Abstract :
Because extensive dangerous and grueling work is still performed at disaster restoration work sites, research and development of unmanned execution technologies for use to enhance safety has been undertaken. This report presents an outline of research and development concerning autonomous excavation by hydraulic excavator performed by applying an IT execution system. As a result of the verification of the excavation motion, finishing excavation was confirmed that the difference between the planned trajectory and the trajectory of the actual movement of the tip of the bucket can be kept within 0.1 m. It also achieved autonomous loading of the crawler dump truck.
