Recent advances in visually guided mobile robotics and visual object recognition  promise to enable us to build home robot assistants that can work with people, knowing about the home, the objects in the home, and their use.  At UBC we have developed a mobile robot, Curious George, that can search a small room and photograph objects from a target list.  The robot learns how to identify objects by searching the web, gathering images showing the objects, and then learns how to find the objects in the room.  The robot then maps the room and finds a route that lets it search for the objects, and returns with a set of images showing the objects it has found. Curious George won the recently held Semantic Robot Vision Challenge.More generally, such robots can learn the appearance of classes of objects and then recognize them, sometimes using the context in which they appear.  But these robots need to comb through the images, finding distinctive features of the objects, and build complex classifiers from the images.  The robots themselves need to be agile and compact.We are now applying for new robots and computation servers that will enable us to experiment in realistic environments such as a home.  The servers need substantial memory since the data we must understand for feature learning comprises thousands of images, for example, the record of a robot's experience in the home.  Mapping also stretches the capabilities of computing systems since the robot acquires tens of thousands of landmarks while traversing a home.  Finally, to utilize context in visual search we need to learn the spatial relations between many different objects and their properties.

视觉引导的移动的机器人技术和视觉物体识别技术的最新进展有望使我们能够建造家庭机器人助手，这些机器人可以与人一起工作，了解家庭，家庭中的物体及其用途。在UBC，我们开发了一个移动的机器人，好奇的乔治，它可以搜索一个小房间并从目标列表中拍摄物体。机器人学习如何通过搜索网络来识别物体，收集显示物体的图像，然后学习如何在房间中找到物体。然后机器人绘制房间地图并找到一条可以让它搜索物体的路线，然后返回一组显示它找到的物体的图像。好奇的乔治赢得了最近举行的语义机器人视觉挑战赛。更普遍的是，这样的机器人可以学习物体类别的外观，然后识别它们，有时使用它们出现的背景。但这些机器人需要梳理图像，找到物体的独特特征，并从图像中构建复杂的分类器。机器人本身需要灵活和紧凑。我们现在正在申请新的机器人和计算服务器，使我们能够在家庭等现实环境中进行实验。服务器需要大量内存，因为我们必须了解的数据特征学习包括成千上万的图像，例如，一个机器人在家里的经验记录。映射也延伸了计算系统的能力，因为机器人在穿越一个家时获得了成千上万的地标。最后，为了在视觉搜索中利用上下文，我们需要学习许多不同对象及其属性之间的空间关系。
