Original Abstract

Shape Memory Alloy can be plastically deformed when cool and it will returne to its original dimensions by the heating. This phenomenon was named as a Shape Memory Effect and it was discovered in 1932 by Swedish physicist. The mechanical motion in SMA is caused by the changes of crystalline structure of SMA. In 1971 there was made the first really sophisticated machine - artifical heart. The most flexible and beneficial Shape Memory Alloy, that has been discovered so far, for engineering applications is an Nickel-Titanium (Ni-Ti) compound. When using the SMA in the practical applications, it is necessary to reckon with certain constraint conditions. By providing the current flow through the SMA drive we achieve the change of temperature thanks to its electrical resistance and thereby it causes the SME. This method of control was also used in the construction of a six-legged stepping robot at the authors’ department in Brno University of technology.
