Error analysis of dead reckoning of multi-legged robots

This paper describes a method of analyzing the error of dead reckoning of multilegged robots. In dead reckoning of multilegged robots, the body posture and contact positions of legs are alternately estimated. The estimated error is accumulated in locomotion. We derive the basic equations for estimation of the error of body posture and the contact positions based on the small displacement analysis. The 3D distribution of the error is analyzed by singular value decomposition.
