RT Corporation Cooperates in Communication Network Demonstration Experiment with Quadruped Robots at a Construction Site
RT Corporation collaborated with Tokyu Construction Co., Ltd. on a communication network verification and demonstration experiment using their domestically developed quadruped robots at a construction site from November to December 2025. This experiment aims to verify the stable operation of robots and the possibility of information sharing in uneven terrain environments, addressing social issues such as labor shortages and economic security.

RT Corporation (Headquarters: Chiyoda-ku, Tokyo; Representative Director: Yukiko Nakagawa; hereinafter, RT) cooperated with Tokyu Construction Co., Ltd. in a technical verification and demonstration experiment (hereinafter, this demonstration) of a communication network for robots at a construction site being built by Tokyu Construction Co., Ltd., using RT's domestically developed quadruped robots. This demonstration was conducted from November to December 2025.
This demonstration was realized because the technical themes of both companies partially overlapped: Tokyu Construction Co., Ltd. is advancing the implementation of a wireless communication network for robots (*), and RT is developing domestically produced quadruped robots and conducting on-site verification in actual environments.
* Refer to Tokyu Construction Co., Ltd.'s news release dated March 13, 2025 (https://www.tokyu-cnst.co.jp/topics/2747.html).
Through this demonstration, RT verified whether quadruped robots could operate stably and acquire/share information via a communication network in diverse environments, not limited to construction sites, but also including uneven terrain and environments with changing conditions. The aim was to confirm the potential for utilizing quadruped robots not limited to specific industry applications, and to organize challenges and lead to technical development for future practical use.
■ Background (Challenges) and Objectives
In recent years, the environment surrounding social infrastructure and industrial sites has changed significantly. In addition to responding to labor shortages and the sophistication of work environments, there is a growing expectation for domestically produced quadruped robots for patrol, inspection, and remote support from the perspective of economic security. On the other hand, sites are not always robot-friendly environments, and many on-site demonstration experiments are necessary for practical application. In this demonstration, an experiment was conducted as one of the diverse uneven terrain environments expected at a construction site under construction. Specifically, the following challenges exist in real environments:
Unstable or limited communication environment
Constantly changing uneven terrain environments such as steps, slopes, and temporary structures (stairs, scaffolding, etc.)
Walkable areas that change daily due to the progress of work processes
Risk assessment at construction sites and safety measures during experiments for collaboration with people
This demonstration aimed to verify whether quadruped robots could operate stably and acquire/share information via a wireless network under these site-specific constraints. Therefore, video transmission tests and demonstration experiments in various walking environments were conducted at an actual construction site.
■ Overview of the Demonstration Experiment
This demonstration was conducted as part of the development of quadruped robots. Equipped with external devices such as cameras provided by Tokyu Construction Co., Ltd., the robots traversed environments including steps, slopes, and obstacles, verifying traversability and operational issues in the uneven terrain specific to construction sites. Risk assessments were also conducted to confirm that there were no problems with points considered dangerous during normal patrols with people at construction sites.
■ Main Achievements (Achievement of Verification Objectives)
Accumulated traversability evaluation data for quadruped robots in environments with mixed uneven terrain and temporary structures.
Organized the effectiveness of combining communication technology and mobile robots as a solution, and identified areas for future improvement.
These achievements also provided developmental challenges and basic knowledge for deployment in diverse fields such as infrastructure inspection, plants, and disaster response, not limited to construction sites.
Walking on designated paths, walking on punched surfaces
Walking on leveled surfaces, walking on uneven terrain
Scenes from the quadruped robot demonstration experiment
■ RT's Future Outlook in Robot Development
RT is currently developing legged robots, including quadruped robots, and is in the phase of not only developing basic functions but also co-creating application development and the practical application of domestically produced robots. Based on the insights gained from this demonstration, RT will widely solicit verification fields for practical operation in other industries and applications, not limited to the construction sector. Furthermore, RT plans to accelerate the industrialization of domestically produced quadruped robots by considering collaboration with companies that already have experience operating quadruped robots from other manufacturers.
