基于情境感知的服务系统(英文)

The paper gives an overview of a recently started research project addressing the question:Can context be exploited to add value to IT-services?Beyond today's way-finding services based on GPS and maps,we believe there is a new class of context-aware pervasive services making good use of a broad range of context information(e.g.identity,time of day,temperature,history as well as relative location of friends and belongings).Last but not least we believe one can find ways of adding value to IT-services by using disembodied conversational agents based on voice,sounds and visual signals integrated into the environment, instead of being guided by explicit directions shown on a display.The project aims at giving both new fundamental insight about the theory behind IT-services,their architecture and user interfaces and at building a number of prototypes demonstrating innovative context-aware pervasive IT-services.

模块化机器人的模块形态特性

针对目前尚无一种通用的方法对模块形态与模块化机器人的性能关系进行分析研究,以EMERGE模块形态为目标对象,基于进化设计的思想,提出一种模块形态的评估方法。首先,依据模块可用的连接面数量及其相对位置对模块形态进行分类分析。然后采用结构化的进化设计策略,以平面的移动任务为算例,在机器人仿真平台中分别对由不同种类形态的模块组建的机器人进化,得到每种模块形态下性能最优的机器人,并比较各自的性能。最后,对不同种类的最优性能的仿真机器人进行实体机器人验证。结果表明该评估方法可有效提高设计高性能模块化机器人的效率,仿真和实体机器人试验验证了方法的有效性。
