Size and weight reduction of semicircular duplex manipulator for rescue operation

Applications of robots for rescue operations have attracted considerable attention. However, at real disaster sites, some of the spaces in the rubble are so narrow that conventional rescue mobile robots cannot pass through them. Hence, the development of a robotized endoscope is expected. In this study, we redesigned our previous rescue manipulator to downsize its body without losing robustness. We developed a new small-sized duplex manipulator and successfully reduced its size by 70%.
