Robotic Eyes with 7 DOFs: Structural Design and Motion Simulation

Abstract

© 2019, CISM International Centre for Mechanical Sciences. The paper presents the structural design and motion simulation of the robotic eyes with the characteristics of the female eye. The eyeballs/eyelids drive system with total 7 DOFs is proposed. The eyeballs drive system has 3 DOFs and enables the rotation of both eyeballs together around the pitch axis and their independent rotation around the yaw axis. The proposed solution enables the installation of cameras directly into the eyeballs. Also, it is possible to independently rotate the upper/lower eyelids of each eye, where the eyelids, in relation to the eyeballs, are rotated in two planes. Motion simulation of eyeball and upper/lower eyelids is performed. For the range of the motion that corresponds to the human eye, the angular velocities of the eyeball and upper/lower eyelids reach and exceed the kinematic parameters of the human eye.
