| Abstract: | A mechanical model of the articulated arm of animal was presented, the similarity on biomechanics behavior and the difference on mechanical characteristics of SMA (shape memory alloy) and skeletal muscle were discussed. Based on the bionics, the technology of driving a bionic rotary joint by SMA wires was studied. The control circuit which can realize SMA's sensing ability and a bionic rotary joint actuator driven by SMA wires was developed. Utilizing this joint actuator, a micro articulated arm with two degrees of freedom was developed, which can be used in micro walking robot and artificial limb. |
