There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract:
In this thesis, we present a control framework for robotic manipulators, which compute solution while satisfying multiple constraints like torque, orientation, tracking, and safety in a unified manner. This is achieved by designing Rapidly Exponentially Stabilizing Control Lyapunov Function (RESCLF) and Control Barrier Functions (CBF) in operational space. We extend the framework to the robust formulation when parameters of the manipulators are not fully known and prove the convergence for the robust formulation. Finally, we extend the framework to wheeled inverted pendulum humanoid robot using a hierarchical framework for whole-body control of the humanoid robot. Finally, we propose to extend the framework to multiple manipulators for co-operative manipulation and implement it on actual 7-DoF KUKA LBR iiwa manipulator.
