水下企鹅AquaPenguins_Festo仿生技术: 水下企鹅- 技术-水下自动运载工具AquaPenguins - technology-bearers as autonomous underwater vehicle.与它自然界的原型一样，来自费斯托（Festo）公司的水下企鹅具有一个带水动力的身体轮廓。其优雅的推进力以及其可向各个方向移动的机翼头部和尾部，让机器人企鹅可以在狭窄的空间条件下自由穿行，并且在必要时及时出现甚至可以向后游——这一点可不像它们的自然界的原型。仿生企鹅设计成水下自动运载工具，可以自由定位并且可在水池中穿行。这种工具有一个3D的海豚音声纳系统，使得“企鹅”可以与周围的伙伴们交流，比如避免互相碰撞。Like its natural archetype, the AquaPenguin from Festo has a hydrodynamic body contour. Its elegant wing propulsion and its head and tail sections, which can be moved in all directions, allow the robotic penguins to manoeuvre in cramped spatial conditions, to turn on the spot when necessary and – unlike their biological counterparts – even to swim backwards. The bionic Penguins are designed as autonomous underwater vehicles that independently orient themselves and navigate through the water basin. They are supported by a 3D sonar system which, as with dolphins, allows communication with their surroundings and with other robotic penguins – for example to avoid collisions.
