Theory and Applications of Parallel Robots
Design, control and dexterity optimization of a dual-arm micro-surgical system for ophthalmic surgery.
Design of high precision parallel robots with guaranteed backlash prevention within a specified workspace.
Parallel Robot Design and Workspace Determinantion for Cochlear Implant Surgery.
Parallel Unit Development for Minimally Invasive Surgery (MIS) of the Throat and Upper Airways.
Former Research Work:
Analyzed inverse and direct kinematics of translational parallel manipulator (TPM) using line geometry elements and proposed a geometric approach for TPM kinematics.
Synthesized three-legged TPM architectures based on displacement group theory and explored the applicability of displacement subgroups in mechanism synthesis.
Investigated extreme distance between two spatial circles and its application on robotic manipulators.
Synthesized planar four-bar linkages in order to:
I. Replace a gear train to avoid backlash.
II. Trace a straight-line with a coupler point.
