We have been working on the development of scaffold free cell delivery system, and showing good results in the regeneration of rabbit osteochondral defect for more than three years by implantation of molded mesenchymal stem cells construct without use of exogenous factors. The entire procedure is simple, yet it takes time and labor to build a single construct by even experienced hands. Therefore, this study was aimed to develop a cell processing robot for building scaffoldfree HD MACs (High-Density Mesenchymal stem cell Autologous Constructs) for cartilage regeneration. As a result, the scaffold-free HD MACs could be obtained with manual procedure just as the same without contamination. We have implanted the construct in a rabbit with osteochondral defect in the knee. In this study, we have developed a cell processing robot for cartilage regeneration. The entire system is almost GMP ready. We are preparing clinical trials at Kyushu University Hospital for HD MACs implantation to cartilage defect with this robot system.

This study addresses the development of a robot for inspection of old bridges. By suspending the robot with a wire and controlling the wire length, the movement of the robot is realized. The robot mounts a high-definition camera and aims to detect cracks on the concrete surface of the bridge using this camera. An inspection method using an unmanned aerial vehicle (UAV) has been proposed. Compared to the method using an unmanned aerial vehicle, the wire suspended robot system has the advantage of insensitivity to wind and ability to carry heavy equipments, this makes it possible to install a high-definition camera and a cleaning function to find cracks that are difficult to detect due to dirt.

Background: In order to study the interference of wired transmission mode on robot motion, a mobile robot attitude calculation and debugging system based on radio frequency (RF) technology is proposed. Methods: Microcontroller STM32 has been used as the control core for the attitude information of the robot by using MEMS gyroscope and accelerometer. The optimal attitude Angle of the robot is calculated through nRF24L01 which is the core of the wireless communication module, attitude acquisition module and wireless data communication upper computer application platform. Results: The results shows that the positioning accuracy is better than±5mm. Conclusion: The experimental results show that the proposed attitude solving and debugging system of mobile robot based on RF technology has better reliability and real-time performance. The propped model is convenient for debugging of mobile robot system and has certain engineering application value.

Self-replicating robot systems (SRRSs) are a new prospective paradigm for robotic exploration. They can potentially facilitate lower mission costs and enhance mission capabilities by allowing some materials, which are needed for robotic system construction, to be collected in situ and used for robot fabrication. The use of a self-replicating robot system can potentially lower risk aversion, due to the ability to potentially replenish lost or damaged robots, and may increase the likelihood of mission success. This paper proposes and compares system configurations of an SRRS. A simulation system was designed and is used to model how an SRRS performs based on its system configuration, attributes, and operating environment. Experiments were conducted using this simulation and the results are presented.
