Abstract
In this paper, shape memory polymers (SMPs) are reviewed, as they have demonstrated exceptional properties that make them suitable as advanced materials for current and potential applications, particularly in robotics. However, the thermomechanical properties and traditional shape memory features are somewhat limited due to their ability to recover their original shape solely through the use of a heating source. SMPs not only possess remarkable mechanical and shape memory properties but also their ease of fabrication makes them suitable candidates for numerous applications. In this research, an artificial muscle equipped with a shape memory polymer is introduced, and its mechanical properties are measured and tested in a simple gripping and releasing mechanism. The results showed that the device is capable of performing cyclic loading and provides a force-to-energy ratio of 0.25. In future, the possibility of using this apparatus in robotic application such as surgical operation and crop harvester will be studied and evaluated.
