The Advanced Defense Technology Center is in charge of not only researching M&S, robot systems, human engineering technology, and NBC defense technology but also promoting research programs of future weapon and equipment systems by utilizing advanced technologies. Simulator on Integrated Equipment　Systems In order to conduct effective R&D, it is crucial to investigate an optimum requirement of each equipment system based on an overall performance as SoS (System of Systems). This is a research on the simulator which can evaluate such an overall performance by creating virtual battle space on computer. Portable Robot Recognized is effectiveness of a small-sized and light-weighted robot for defense purpose. The modular mechanism of its mobility / manipulation and the modularity of its control system are key technologies for development of such a robot. This is a tele-operated robot whose size and weight are man-portable. It has a capability to carry out various missions such as reconnaissance inside / around a building, detection / disposal of explosive devices and so on. Advanced Soldier Combat System This integrated personal equipment system is researched to systemize electronic equipments and a bullet proof jacket. The system enables infantry to prosecute various missions effectively by sharing the battle field information visually with allies using advanced technologies such as a light weight head mounted display, wearable computer network etc. The photo shows a prototype model. Palm-seized Automated Chemical Agent Detector Research on palm-seized automated chemical agent gas detector is executing as a collaboration between Japan and U.S.
