We, the CAFE project, are working on the research and development of “Collaborative AI robots for adaptation of diverse environments and innovation of infrastructure construction” in the group of Moonshot Goal #3 “AI robots that learn and act by themselves and coexist with people.” The CAFE project is derived from the Collaborative AI Field robot Everywhere. Starting in 2024, we will transition to a new organizational structure, aiming for system integration of the technologies we have developed so far.
Disaster response at the site of
a natural disaster in 2050
In Japan, where we live, various natural disasters frequently occur across the country. To protect the lives of the people living here and minimize the damage caused by these disasters, further technological development for emergency restoration is desired. Therefore, in this project, We will conduct research and development of “collaborative AI robots” that can respond flexibly to different situations and perform tasks in difficult environments such as disaster sites. This technology will also be useful in the construction and maintenance of infrastructure on the ground.
The illustration on the left depicts the concept of emergency restoration at a natural disaster site in 2050. Multiple field robots assess the disaster situation accurately based on sensing data, and then engage in collaborative work to handle unexpected situations while carrying out emergency restoration. As a milestone for this project by 2025, we aim to develop a prototype system of multiple collaborative AI robots capable of flexibly responding to unforeseen situations, specifically to mitigate the impact of natural disasters, with a focus on river blockage disasters.
The overarching goal of this research and development project is “to achieve infrastructure construction adapted to various environments through a collaborative AI robot system.” To realize this goal, we have established three research and development themes: 1. AI Robot System Revolutionizing Earthwork (hardware), 2. Dynamic Collaboration System for Multiple Robots (AI controlling multiple robots), and 3. Sensor Pod System Overseeing the Site (sensing technology and AI evaluating the environment). We have been advancing research and development on these themes in parallel.
From 2024 onwards, as shown in the figure on the right, we will focus on advancing robotic systems capable of responding to natural disasters, particularly river blockage disasters. Alongside technological innovations, we aim to integrate these technologies into a cohesive system.
The project named “Collaborative AI robots for adaptation of diverse environments and innovation of infrastructure construction,” aims to develop collaborative field robots that can be useful in “natural disaster response.” To achieve this goal, robots must be able to flexibly respond to various situations. In this project, we aim to achieve this goal through a variety of approaches.
The introduction to this project is provided in the section “Overview of CAFE Project,” and I, the project manager, would like to share three things that are important to me in this project.
The first is the basic philosophy of this project. The basic philosophy of this project is “to develop technology that is useful to people.” It is the same basic philosophy that I have always cherished in my robotics research. I do not want to excuse myself from saying, “I completed my research, and it will be practical use if somebody complete other required parts.” in this policy.
The second aspect is the horizontal connection between the researchers and engineers. This project requires interdisciplinary cooperation, and it will not be possible without “civil engineering,” “mechanical engineering,” and “AI.” Therefore, we would like to promote the research and development, where researchers from each field respect each other's field and closely exchange information to strengthen the horizontal collaboration.
The third is a field-oriented approach. In this project, we do not want to artificially create and demonstrate a field where robots can efficiently operate. Instead, we want to develop robots that can operate in actual fields.
The members of this project are very powerful researchers and engineers who are currently active in their respective research fields. I am happy to work with them. Please look forward to our future research.
