A calibration framework for swarming ASVs' system design
Published 2012“…In order to increase the robot's buoyancy, high density foam has been added to the previous design and results of the new rudder simulation effect is also been presented. Due to the delay of the NMEAs data and the limitation of an 8-bit micro-controller, complex control has been deferred until sometime in the future.…”

Modeling and control of an articulated multibody aircraft
Published 2022“…The control effect of the moving abdomen was comparable to the control surfaces, with lateral abdominal motion substituting for an aerodynamic rudder to achieve coordinated turns. Vertical fuselage motion achieved the same effect as an elevator, and included potentially useful transient torque reactions both up and down. …”
