在世界各地，自然或人為災難隨時可能發生。災難回應作為災難處理的重要環節顯得尤為重要，隨著科學技術的進步和提高，人們希望通過使用各種科學手段來提高災難的回應效率。機器人技術作為21世紀高科技結合的產物被廣泛應用於這一領域。一般情況下，設計者會採用功能集成的思想對機器人進行設計，他們的主要設計思想是根據自己對環境的理解和認知得到機器人的設計需求，然後針對設計需求，通過功能集成和疊加的方式來完成對機器人的設計，採用這種方式機器人一旦設計完畢，其功能也隨之確立並不可更改，這種設計思想是基於環境狀況的，即一旦災難現場的環境不符合預先的設定，機器人的執行能力將大幅下降，同時功能疊加的設計方式會產生功能與功能之間相互約束，影響其專業性。 / 本文介紹了一種基於分散式設計思想的全新設計理念，並且根據這一理念設計了一套基於任務需求的救援機器人系統。機器人系統不會根據設計者對災難現場的預先理解和認知而被一體化設計，相反根據"如何到達"和"如何操作"把機器人系統拆分成移動單元和操作單元兩個環節，針對每個環節分別設計了符合現場需求的通用移動模組和任務執行模組，救援人員可以根據災難現場的即時任務需求而迅速搭建出有針對性的機器人系統任務解決方案，和傳統的機器人系統相比，具適應性廣、靈活性高、針對性強等特點。 / 在本論文中，對三種通用的移動平臺和兩種通用的模組化關節以及一個快速連接器分別進行了結構設計、理論分析及樣機設計，並採用基本的通用模組，根據即時的任務需求構建出有針對性的多個機器人系統。實驗表明該機器人系統可以提供對災難環境有針對性的系統解決方案，具有一定容錯性、經濟性及災難環境的適應性。文章的創新點如下，首次針對于救援機器人提出分散式的設計思想，並以該思想為基礎設計了基於通用模組的救援機器人系統，針對不同任務對移動性能的不同要求設計了三種移動平臺，為滿足不同的救援操作要求設計了兩種模組化關節以及快速連接器。同時，文中為實際的地震救援任務提出了一套救援機器人系統解決方案。 / Natural and man-made disasters nowadays still present a large amount of risk. Disaster response is an important phase of disaster management, and the enhancement of its effectiveness and accountability has attracted an increasing amount of attention. Robots can help rescuers in doing this task because of its wide range of applications. In general, the rescue robot concept assumes one or more targeted tasks while design, and one or a set of robot(s) is/are designed by integrating different functions to accomplish those tasks. Once the design of a robot is finished, its function cannot be changed. However, this kind of design is environment-dependent, as once a disaster environment changes, the execution performance of the robot will reduce. Furthermore the function-integrated design concept may cause internal constraints between functions, and fail to provide a targeted solution for different disaster environments. / This dissertation introduces a novel design concept, based on which a requirement-oriented rescue robot system is developed. This design concept adopts a distributed strategy, according to which tasks are no longer seen as a whole but divided into two parts: traversability and operation. Several functional modules are designed to meet the different requirements of the two parts separately, and the entire robot system can be assembled using different functional modules according to the real-time requirements of the disaster environment. Compared with the traditional rescue robot system, this system can provide a more targeted solution for different disaster situations, and is more adaptable and flexible. / This dissertation details the basic functional modules, including three kinds of mobile bases for traversability and two sets of modular joints for operation, and analyzes a quick connector that makes the connection easier and more convenient. Several possible combinations of the rescue robot system are displayed to show how to construct a rescue robot system according to different requirements. This kind of rescue robot system can provide targeted solutions to different disaster tasks. Robustness is also enhanced, as the replacement of the functional modules is flexible and easy to overhaul. Furthermore, the functional modules can be decomposed and reused to make the robot system more economical. This dissertation makes several contributions. It presents a systematic solution for rescue robot, develops three mobile bases for high traversability and two kinds of modular joints and a quick connector for rescue operation. Furthermore, it also develops a rescue robot system for missions in earthquake. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Yang, Yong. / Thesis (Ph.D.) Chinese University of Hong Kong, 2014. / Includes bibliographical references (leaves 226-236). / Abstracts also in Chinese.
