Abstract
There are a lot of visual defect people who want to go away. But visually impaired people cannot go away themselves without other help. Due to the high cost to bring up a dog, it is difficult to supply a guide dog to all visually impaired people. A bus is the most important transportation tool for the impaired people. Therefore, a guide robot, which can be available instead of a guide dog, is requested. In this case, movement mechanism that can ride a bus step is important factor for the guide dog robot. This research develops six legged type movement mechanisms that can get over the bus step.
