This paper presents a soft hydraulic artificial muscle (SHAM) design, which replaces the cylinder, rod and piston in traditional hydraulic cylinder with soft structures. The presented muscle has the advantages of high output force level and good adaptability to environment. Modelling and simulation are conducted after introducing the working principle of the SHAM. Simulation results show that the output force can be as large as 160N with 0.8MPa input pressure. The effect of mixed air into the working fluid has also been investigated and discussed. Above advantages make the SHAM perfect for applications such as exoskeletons.
