Recently, the development of mobile robots is actively pursued. These robots are expected to have high mobility, allowing them to work in various scenarios such as rescue and exploration. Therefore, we focused on the hexapod robot for stable operation in an irregular terrain. We developed a leg using the parallel linkage mechanism and pneumatic rubber artificial muscles, and constructed a model of the legs. The model reproduced the experimental result. Then, we developed improved hexapod robot which can support its weight mechanically using these legs. Furthermore, the robot is assembled all system for walking. Also, we demonstrated that the robot could walk with high load of 300[N].

Pneumatic rubber Artificial muscle (PAM) has high back drivability and high output. However, PAM's Repetitive durability is low and not less well understood. Observing broken PAM which was made of carbon and latex rubber, there were breakage of fiber in it. Thus, we focused Aramid fiber that has high maximum shearing stress and abrasion resistance. Then, we compared load characteristics and repetitive durability between PAMs using carbon fiber and aramid fiber. Experimental result showed that load characteristic of PAM using aramid fiber is equal to PAM using carbon fiber. Furthermore, repetitive durability of PAM using Aramid fiber is 6times better than one using carbon fiber.On the other hand, we tried to develop reparable PAM using thermoplastic elastomer (TPE). And load characteristic experiment and repetitive durability experiment were conducted. As a result, load characteristic of PAM using TPE was equal to previous PAMs. For future works, we are planning to simulate PAM from the viewpoint of material mechanics. Meanwhile, we are planning to improve repetitive durability of PAM using TPE.
