ABSTRACT:
A construction element that contains a shape memory element which changes shape in response to a change in the temperature of the memory element. The temperature is varied by a fluid which flows through channels adjacent to the shape memory element. The fluid typically flows through an inner channel of the memory element and an outer element formed by the element and an outer elastic pipe. A plurality of shape memory elements can be coupled together to create a robotic arm or an endoscopic instrument. The arm or endoscope can change shape by varying the temperature of the fluid. The fluid temperature and the corresponding shape of the arm/endoscope can be controlled by a computer.
