Abstract(in English) | For controlling mobile robots within the framework of statistical inference, precise models of state transition and observation processes are crucial. Although these models can be obtained if the robot makes use of external information, such a setting makes the robot's applicability narrow and the implementation costly. In this study, we propose a method to identify these models from the robot's own observation. In this method, an environment is formulated as a parameterized probabilistic model in consideration of a geometric property and sensory non-linearity. The unknown parameters are determined based on the maximum likelihood estimation. We evaluated the performance of the proposed method using synthetic and real datasets. The results showed that the method successfully obtained the environmental model with a fairly good precision only from the robot's own sensory information. |
