本课题的目标是建立一种新的高机动水下机器人的设计和控制方法,用于水下结构物的检测。紧凑的蛋形机器人将使我们能够将检查仪器带到那些很少被检查的复杂水下结构。其中包括核电站的反应堆内部和水电站的设备,这两者都需要进入危险地点进行检查和监测。此外,高机动性机器人可以应用于港口安全,海上设施监控和电缆网络维护。将寻求与能源工业和其他方面的合作,以推广新的设计方法。该项目将研究没有方向舵和附属物的蛋形机器人。紧凑光滑的身体形状使机器人能够接近具有多轴射流的复杂水下结构。然而,椭球体是水动力不稳定的,因此不适合从传统的潜艇设计的观点。该项目将讨论车辆的不稳定性可以用于快速转弯和敏捷运动,这是一种类似于航空学中控制配置车辆的设计概念,以及如何从动力学和控制的角度优化设计此类车辆。该项目旨在通过高速水阀的设计、多轴射流的有效配置、车身形状的优化和控制综合来稳定车辆,同时最大限度地提高机动能力。
英文摘要
The goal of this project is to establish a new design and control method for highly maneuverable underwater robots to perform inspection of underwater structures. Compact, egg-shaped robots will allow us to bring inspection instruments to those complex underwater structures that have seldom been inspected. Those include reactor internals of nuclear power plants and the equipment of hydro-dams, both of which require access to dangerous sites for inspection and monitoring. Furthermore, the highly maneuverable robot can be applied to port security, offshore facility monitoring, and cable network maintenance. Collaborations with energy industries and others will be sought for disseminating the new design method.The project will study egg-shaped robots, having no rudders and appendages. The compact and smooth body shape allows the robot to access complex underwater structures with multi-axis jets. The spheroidal vehicle, however, is hydro-dynamically unstable and thereby not appropriate from the traditional submarine design viewpoint. This project will argue that the vehicle instability can be exploited for quick turning and agile movements, a design concept similar to Control-Configured Vehicles in aeronautics, and how such vehicles can be designed optimally from the dynamics and control viewpoint. The project aims to stabilize the vehicle, yet maximize the maneuvering capability, through the design of high-speed water valves, effective configuration of multi-axis jets, optimization of the vehicle body shape, and control synthesis.
