Baleka: A Bipedal Robot for Studying Rapid Maneuverability

open access: yesFrontiers in Mechanical Engineering, 2020
In nature animals are highly adapted to perform rapid maneuvers. However, these maneuvers have generally been avoided by robotics researchers due to the complex (and poorly-understood) dynamics they entail.

Maneuverability of a flat-streamlined underwater vehicle [PDF]

open access: yesProceedings 2001 ICRA. IEEE International Conference on Robotics and Automation (Cat. No.01CH37164), 2002
Maneuverability describes a vehicle's ability to change course or turn. Maneuverability of conventional underwater vehicles, such as torpedoes, can be determined by altering the position and length of control fins. To perform large-area surveying tasks, autonomous underwater vehicles (AUV) generally require different maneuverability characteristics in ...

High Maneuverability Airframe: Investigation of Fin and Canard Sizing for Optimum Maneuverability [PDF]

open access: yes, 2014
Abstract : The next generation of precision munitions is likely to use a non-rolling airframe with 4 independent canards to increase maneuverability of the munition such that it can engage moving as well as stationary targets. The design of such a precision munition requires increased understanding of the airframe, of maneuver technology, and of ...
