Recent studies have shown that many fish are similarly maneuverable, but differ in their abilities to stabilize themselves in the turbulent environments typical of the natural world. Differences in stabilizing/maneuvering mechanisms affect behavior, habitat choices and fish distributions. The proposed research by Dr. Webb will contribute to basic knowledge by measuring the abilities of four species of fishes differing in body and control-surface form to stabilize the body and swimming trajectories when they are perturbed by outside hydrodynamic disturbances. Furthermore, the locomotor prowess of fishes cannot be matched in any given human-fabricated underwater vehicles. Therefore, the proposed research will contribute to applied knowledge by providing sources for novel designs for submersibles that must increasingly operate in shore and near shore situations. Data will be obtained using high-speed video as fish stabilize themselves in response to disturbances during median and paired fin (MPF) hovering and swimming, and during body-caudal fin (BCF) swimming. The flexibility and integrity of stability mechanisms will be modified in these situations to determine the importance of control-system design. These species span major morphological systems used in stability control. The project is explicitly designed to have a major role in undergraduate education, as well as graduate training.

最近的研究表明，许多鱼类都具有类似的机动性，但在自然界典型的动荡环境中稳定自己的能力有所不同。稳定/机动机制的差异影响鱼类的行为、栖息地选择和分布。韦伯博士提出的研究将通过测量四种不同身体和控制面形式的鱼类在受到外部水动力干扰时稳定身体和游泳轨迹的能力，为基础知识做出贡献。此外，任何人工制造的水下航行器都无法与鱼类的运动能力相媲美。因此，拟议的研究将通过为必须越来越多地在岸上和近岸情况下操作的潜水器提供新设计的来源，从而有助于应用知识。在中鳍和对鳍（MPF）悬停和游泳以及身体尾鳍（BCF）游泳过程中，鱼类在干扰下稳定自身，使用高速视频获取数据。在这些情况下，稳定机制的灵活性和完整性将被修改，以确定控制系统设计的重要性。这些物种跨越用于稳定性控制的主要形态系统。该项目被明确设计为在本科教育和研究生培养中发挥主要作用。
