Construction, Materials Handling, and snow removal machinery are useful. However, because of their large size and high output, accidents can be serious. We view these machines, people, and the environment as a single system. Our goal is for humans, AI, and machines to comfortably cooperate with each other and also with the environment. To this goal, we aim to establish the necessary dynamic analysis methods, DXR methods, and scientific guidelines for design and operation. We believe that our research can make social infrastructures better, safer, and more secure, and we are currently promoting related "science of technology".
