計畫編號：NSC94-2413-H032-013研究期間：200508~200607研究經費：488,000[[abstract]]本研究為接續93年度的研究計畫，這兩年的計畫將設計出一套籃球模擬戰術系統，這套系統核心在於利用電腦軟體將比賽所拍攝下來的錄影帶，剪輯出較具代表性或重複性較高的片段，再將影像套入電腦程式中，程式會自動抓出進攻或防守球員的移動軌跡，如此，教練及球員可在最短的時間瞭解影帶中的戰術變化。另外，教練可將本隊的戰術拍下，形成軌跡圖後讓球員反覆觀看。除此之外，教練可利用另一套軟體，將正確的攻守反應戰術作一定位，由球員選擇防守的位置及移動路線，藉此評估該球員對該戰術的認知程度。本計畫的發展方向主要在於學術的研究及籃球攻防戰術之標準模式的評估分析，除希望可做為教育訓練的輔助工具外，希望能將資訊科學化的訓練替代土法煉鋼的方式，因此本系統的完成除了對於學術上有一份貢獻外，更是體育與科技結合最佳表現。[[sponsorship]]行政院國家科學委員

The design and intelligent control of an autonomous mobile robot

This thesis presents an investigation into the problems of exploration, map building and collision free navigation for intelligent autonomous mobile robots. The project began with an extensive review of currently available literature in the field of mobile robot research, which included intelligent control techniques and their application. It became clear that there was scope for further development with regard to map building and exploration in new and unstructured environments. Animals have an innate propensity to exhibit such abilities, and so the analogous use of artificial neural networks instead of actual neural systems was examined for use as a method of robot mapping. A simulated behaviour based mobile robot was used in conjunction with a growing cell structure neural network to map out new environments. When using the direct application of this algorithm, topological irregularities were observed to be the direct result of correlations within the input data stream. A modification to this basic system was shown to correct the problem, but further developments would be required to produce a generic solution. The mapping algorithms gained through this approach, although more similar to biological systems, are computationally inefficient in comparison to the methods which were subsequently developed. A novel mapping method was proposed based on the robot creating new location vectors, or nodes, when it exceeded a distance threshold from its mapped area. Network parameters were developed to monitor the state of growth of the network and aid the robot search process. In simulation, the combination of the novel mapping and search process were shown to be able to construct maps which could be subsequently used for collision free navigation. To develop greater insights into the control problem and to validate the simulation work the control structures were ported to a prototype mobile robot. The mobile robot was of circular construction, with a synchro-drive wheel configuration, and was equipped with eight ultrasonic distance sensors and an odometric positioning system. It was self-sufficient, incorporating all its power and computational resources. The experiments observed the effects of odometric drift and demonstrated methods of re-correction which were shown to be effective. Both the novel mapping method, and a new algorithm based on an exhaustive mesh search, were shown to be able to explore different environments and subsequently achieve collision free navigation. This was shown in all cases by monitoring the estimates in the positional error which remained within fixed bounds

Promoting Andean children's learning of science through cultural and digital tools

Conference Theme: To see the world and a grain of sand: Learning across levels of space, time, and scaleIn Peru, there is a large achievement gap in rural schools. In order to overcome this problem, the study aims to design environments that enhance science learning through the integration of ICT with cultural artifacts, respecting the Andean culture and empower rural children to pursue lifelong learning. This investigation employs the Cultural-Historical Activity Theory (CHAT) framework, and the Design-Based Research (DBR) methodology using an iterative process of design, implementation and evaluation of the innovative practice.published_or_final_versio
