Kawasaki Heavy Industries has developed the 'Excavator Autonomous Construction System' (hereinafter referred to as this system), achieving autonomous trench excavation by excavator. This enables the 'autonomization' of trench excavation by excavators traditionally carried out by skilled workers in the construction civil engineering site.
This system, controlled by the excavator-mounted controller, plans efficient excavation operations based on input 3D design data and topographical sensing results from lidar, and autonomously determines the excavation volume while performing excavation and dump loading. In our verification test, we confirmed the system's ability to autonomously construct a 2m wide, 0.6m deep, and 10m long trench. Additionally, we have confirmed that besides excavation work, autonomous operations such as leveling the trench floor horizontally and compacting it can also be performed autonomously.
Currently, the shortage of labor due to decreasing population is becoming more pronounced, and in the construction civil engineering industry, training skilled workers and securing talent has become a major challenge. Furthermore, with a strong demand for improving working conditions and increasing productivity, the need for 'autonomization' of work at construction civil engineering sites is expected to increase further. Towards the practical application of this system, we will continue to work on system development to achieve stable autonomous excavation under various soil conditions.
By combining our advanced hydraulic control technology developed over the years and industrial robot control technology, this system has achieved our unique excavator autonomous control as well as high responsiveness, high precision, and high efficiency. Aimed at bringing innovation to the construction civil engineering industry, we will continue to advance further development with our technology and challenges.
