An actuator () includes a moving member () pivotally connected to a base unit () for rotation about an axis. The driving force for rotation of the moving member () relative to the base unit () is provided by a pair of antagonistically operating shape memory alloy (SMA) wires () and transmitted via a torsional spring (). An endoscope, or a snake-like robot (), may include one or more of the actuators ().
