RoboHow aims at enabling robots to competently perform everyday human-scale manipulation activities - both in human working and living environments. The project pursues a knowledge-enabled and plan-based approach to robot programming and control. Its vision is that of a cognitive robot that autonomously performs complex everyday manipulation tasks and extends its repertoire of such by acquiring new skills using web-enabled and experience-based learning as well as by observing humans. This trailer gives an overview of the research approach and the information sources that will be used to teach robots novel tasks.
