This paper involves the geometrical representation, kinematic solution and dimensional optimization of a one degree
of freedom parallel thumb mechanism. The aim of the designing of this mechanism grasping objects by mimicking of a human
thumb. Link length optimization of the mechanism are made around an average human thumb sizes by using Firefly Algorithm
which is a nature inspired optimization algorithm.
