EXTENDABLE HYBRID LINEAR ACTUATOR: A MINI-REVIEW

Abstract

There are many types of different actuators in the field of robotics. For applications where a linear displacement is required, a linear extendable actuator would be the method of choice. The hybrid class of extendable actuators possesses unique features making it suitable for many applications where the soft and rigid types fall short. However, there has not been a clear designation and classification of extendable linear hybrid actuators in the literature. This study addresses this matter and provides the first overview of the hybrid class of extendable actuators. The study performs a categorization and characterization of this class of extendable linear actuators based on their method of operation as well as the inherent unique features separating them from the rest. The study covers different categories of Hybrid actuators, their method of operation, and applications. New research in this field continues to add features to this class of actuators through improvements and added capabilities.
