Most of the spherical unmanned aerial vehicles (SUAVs) use control surfaces. which are functions of aileron and an elevator. to generate control torque. The work proposes a new conceptual design of an SUAV system controlled through center-of-gravity (CG) variations with its path-tracking control law designed for the system. https://www.roneverhart.com/Sheepshead-Bay-Boats-2-Brooklyn-NY/
