Abstract
At present, with the development of robotic technology, many industrial robots for simple operation to replace human have been introduced. Anyhow, there are still many dangerous operation of disaster area of restoration activity and crater observation investigation done by human. We developed the hydraulically actuated hexapod robot named COMET-IV. COMET-IV locomotes autonomously and assists various hazard operations outdoors. In this research, we are using pressure sensor to estimate slope surface and slope angle. We considered body attitude of COMET-IV on slope and using attitude sensor to control body attitude of COMET-IV. Finally, we proved our research by the experiment.
