Learning Spatial Models for Navigation
Typically, autonomous robot navigation relies on a detailed, accurate map. The associated representations, however, do not readily support human-friendly interaction. The approach reported here offers an alternative: navigation with a spatial model and commonsense qualitative spatial reasoning. Both are based on research about how people experience and represent space. The spatial model quickly...
متن کاملSpatial Navigation: Spatial Learning in Real and Virtual Environments
Humans and many non-human animals need to accurately and efficiently navigate from one place to the next in their environment. Over 3,000 years ago the volcanic islands of the Pacific were settled by the people of Polynesia (Gibbons, 2001). These navigators sailed in craft from Samoa to Hawaii covering an area extending some 4,500 km without the benefits of modern navigational equipment. Errors...
متن کاملLearning spatial relationships between objects
Although a manipulator must interact with objects in terms of their full complexity, it is the qualitative structure of the objects in an environment and the relationships between them which define the composition of that environment, and allow for the construction of efficient plans to enable the completion of various elaborate tasks. This paper presents an algorithm which redescribes a scene ...
متن کاملLearning Spatial Relationships: Some Approaches
We consider three approaches to learning natural resource models involving spatial relationships, based respectively on decision tree learning, genetic programming and inductive logic programming. In each case, the results of spatial learning on a natural resource problem are compared with the results of non-spatial learning from the same data, and improvements in predictivity or simplicity of ...
متن کاملLearning Qualitative Spatial Relations for Robotic Navigation
We consider the problem of robots following natural language commands through previously unknown outdoor environments. A robot receives commands in natural language, such as “Navigate around the building to the car left of the fire hydrant and near the tree.” The robot needs first to classify its surrounding objects into categories, using images obtained from its sensors. The result of this cla...
