  Biology can provide biomimetic components and new control principles for
robotics. Developing a robot system equipped with bionic eyes is a difficult
but exciting task. Researchers have been studying the control mechanisms of
bionic eyes for many years and considerable models are available. In this
paper, control model and its implementation on robots for bionic eyes are
reviewed, which covers saccade, smooth pursuit, vergence, vestibule-ocular
reflex (VOR), optokinetic reflex (OKR) and eye-head coordination. What is more,
some problems and possible solutions in the field of bionic eyes are discussed
and analyzed. This review paper can be used as a guide for researchers to
identify potential research problems and solutions of the bionic eyes' motion
control.
