DIMENSIONING METHOD OF SHAPE MEMORY ALLOYS
ACTIVE ELEMENTS OF AN ACTUATOR FOR A ROBOTIC
PREHENSION MODULE
Even it has been recognized that Shape Memory Alloys (SMA) have a
significant potential for deployment actuators, the number of applications of
SMA-based actuators to the present day is still quite small, due to the need of
deep understanding of the thermo-mechanical behaviour of SMA. Thus, the
paper presents a dimensioning method for the electrically heated active
elements of a robotic prehension system in order to obtain maximal stroke and
displacement.
