Abstract
This paper studies understanding of humans' teaching information by an autonomous mobile robot. Two steps of teaching information understanding are introduced in this paper. The first step is to ground the teaching information by reconstructing them through collection of data using the teaching information and acquisition of rules from the data. The second step is to extract the skill implicitly included in the teaching information for learning in a new environment. A simulation using a mobile robot is done to demonstrate the understanding of the humans' teaching information.
