A Context-Based State Estimation Technique for Hybrid Systems
Conference Paper, Proceedings of (ICRA) International Conference on Robotics and Automation, pp. 3935 - 3940, April, 2005
Abstract
This paper proposes an approach to robust state estimation for mobile robots with intermittent dynamics. The approach consists of identifying the robot?s mode of operation by classifying the output of onboard sensors into mode-specific contexts. The underlying technique seeks to efficiently use available sensor information to enable accurate, high-bandwidth mode identification. Context classification is combined with multiple-model filtering in order to significantly improve the accuracy of state estimates for hybrid systems. This approach is validated in simulation and shown experimentally to produce accurate estimates on a jogging robot using low-cost sensors.
