A Non-Axisymmetric Parallel Manipulator for Head Stabilisation in Vitreoretinal Surgery

Abstract

Kingdom 0000-0002-9152-3194 Abstract —A non-axisymmetric parallel manipulator headrest design was previously proposed to counter patient head motion during ophthalmic surgery, and a non-motorized prototype was built. Custom linear actuators were designed, and installed to the headrest manipulator prototype in preparation for kinematic performance test. An inverse kinematic-based control algorithm was implemented, and initial kinematic testing was done. Finally, the future plans for the research are
