Publisher Summary Studies of the relationships between fish form and swimming performance go back several millennia, an interest stimulated by the high speeds achieved by some fishes. More recently, the agility of fishes and other aquatic animals has caught the attention of both biologists and those who seek inspiration from nature for human-designed

A maneuverable, pneumatic underwater glider
2012 Oceans, 2012A coastal (100 meter depth) underwater glider has been developed to serve as a platform for testing advanced perception, planning, and control algorithms to improve glider efficiency and performance. The glider's buoyancy engine is pneumatically powered, and capable of generating large changes in buoyancy.

Analysis of airship lateral maneuverability
Journal of Aircraft, 1991EQUATIONS of motion have been derived and used to investigate analytically lateral and directional maneuverability characteristics of an advanced airship configuration consisting of auxiliary aerodynamic and powered yaw control augmentation. Theoretical expressions for turning radius, sideslip angle, roll angle, and the corresponding rudder deflection ...

Does a Rigid Body Limit Maneuverability?
Journal of Experimental Biology, 2000ABSTRACT Whether a rigid body limits maneuverability depends on how maneuverability is defined. By the current definition, the minimum radius of the turn, a rigid-bodied, spotted boxfish Ostracion meleagris approaches maximum maneuverability, i.e. it can spin around with minimum turning radii near zero.

Aeromechanics of Highly Maneuverable Bats
2008Abstract : Bats fly with astounding agility, maneuverability and efficiency. Their flight mechanics are completely different from those of insects and birds and characterized by several unique aeromechanical features including: (1) complex three-dimensional articulated wing structures, (2) flexible wing skeletons, (3) anisotropic, highly elastic wing ...

Autonomous treaded multiple maneuverable rover
2016 International Conference on Control, Instrumentation, Communication and Computational Technologies (ICCICCT), 2016While designing a compact Unmanned Ground Vehicle (UGV), it must be capable to travel through complex topography on traversing within confined spaces. In many applications, it is practically expedient that the robots adopted must be economical, hence multiple rovers shall be employed to execute a prescribed task. The cost of the rover can be economized

Highly Maneuverable Nursery Straddle Vehicle
Transactions of the ASAE, 1985ABSTRACT A highly maneuverable, wide straddle vehicle was found technically feasible as a prime mover for multi-purpose operations in ornamental nurseries. Hydraulic cylinders incorporated as extensible tie rods enable orthogonal steering of the vehicle.

Kinematics of maneuverable relativistic starship
Acta Astronautica, 2012Abstract Maneuvering a relativistic starship is not as easy as it appears. The closer is its velocity to the speed of light the less maneuverable it appears to be relative to the rest frame. The relativistic kinematic equations are derived and the examples of starship trajectories are calculated on the condition of a constant proper acceleration and ...
