Novel bio-inspired mechatronic articulation with potential for use in space
نویسنده
چکیده
Joints are failure points for deployable systems and moving devices. Their reliability and efficiency are of great concern for space applications. In this paper we present a new biologically inspired joint for space applications that has a minimal number of parts and requires no bearings. Its principle is based on a compliant structure that changes shape with Shape Memory Alloy actuators. An experimental two degrees of freedom prototype joint is built and proves the concept. Analysis of a simple model of the joint shows that further optimization with respect to the motion envelope is possible.

Any section or space in architecture that connects other sections or spaces called a joint. This research proposes using the word "Articulation" instead "Joint", on the basis of the etymology of both words. So in this abstract, the concept of "joint" is meant anywhere the word "Articulation" is mentioned. The present research deals with theoretical aspects of architecture. Its primary goal is t...
