Summary

Our laboratory aims to research "digital manufacturing systems" based on mechatronics, automation and digital technology, working from a broad perspective from design design and prototyping to CNC machine tools, industrial robots, automated transport, sustainable production systems and process elucidation. Toward the IoT and information society synchronized with the development of computers, technological innovations such as machine learning and AI (artificial intelligence) are also actively introduced into our systems. We are also engaged in research and development related to technologies for a sustainable society that takes into account the cooperation between humans and machines and the global environmental impact that will be necessary for the next generation of manufacturing (manufacturers). While "the importance of manufacturing is universal," it is believed that "the technology of how to make things is constantly changing. Toward the needs of a changing society, we will promote research and development of autonomous, distributed, and cooperative "making," "manipulating," and "transporting" based on globally applicable mechatronics technology.
