I. Introduction
The rapid developments in robotic technology and microfabrication process have drawn significant attention to robotic-aided biomedical applications over the past decades. Some of the representative applications include microinjection [1]–[3], microgripper [4], [5], and microrobot [6]–[10]. Compared with traditional manual manipulations with tools such as micropipettes, systems integrated with robotic technology and biomedical equipment make micromanipulations easier and also more accurate, precise, and efficient.
