在这个视频中，我们展示了最近的一个公开实验，两个机器人使用网络指令制作煎饼。在实验中，机器人从万维网上检索制作煎饼的指令，并根据指令生成机器人的行动计划。这个任务是由两个自主机器人共同完成的:第一个机器人打开和关闭橱柜和抽屉，从冰箱里拿一个煎饼粉，交给机器人b。第二个机器人做饭，翻转煎饼，然后把煎饼送回到第一个机器人。实验中与人工智能相关的是使用百科全书知识库将指令翻译成机器人计划，步骤如下:首先，使用公共自然语言解析器解析句子，生成指令的语法树。树的分支然后递归组合成更复杂的描述来创建一个内部表示指令描述的行为,所涉及的对象,地点,时间的限制,使用材料的数量等原始文本中的词是解决机器人的知识库的概念首先在WordNet词汇数据库中查找它们的含义,然后通过利用WordNet和本体,本体之间的映射。本系统采用一种基于短语上下文和从Cyc获取的对象-动作对信息的简单方法来消除可能的词义之间的歧义。

| 课程简介: |
In this video we show a recent public experiment that shows two robots making pancakes using web instructions. In the experiment, the robots retrieve instructions for making pancakes from the World Wide Web and generate robot action plans from the instructions. This task is jointly performed by two autonomous robots: The first robot opens and closes cupboards and drawers, takes a pancake mix from the refrigerator, and hands it to the robot B. The second robot cooks and flips the pancakes, and then delivers them back to the first robot. AI-related in the experiment is using of the encyclopedic knowledge base for the translation of instructions into robot plans which is performed by the following sequence of steps. First, the sentences are parsed using a common natural-language parser to generate a syntax tree of the instructions. The branches of the tree are then recursively combined into more complex descriptions to create an internal representation of the instructions describing the actions, the objects involved, locations, time constraints, the amount of ingredients to be used etc. The words in the original text are resolved to concepts in the robot's knowledge base by first looking up their meanings in the WordNet lexical database, and by then exploiting mappings between WordNet and the Cyc ontology. Our system employs a simple method based on the phrase context and on information about object-action pairs obtained from Cyc to disambiguate between possible word meanings.
