Abstract
This paper presents a novel method for online dynamic parameter identification in wheeled mobile robots with nonholonomic constraints. First, the direct dynamic model of a mobile robot is obtained and reformulated in the linear form of dynamic parameters. Then, an adaptive estimation routine is proposed in order to identify the robot dynamic parameters with high accuracy and in finite time without requiring the measurement of the acceleration state vector. Based on Solidworks/ SimMechanics, a virtual prototype with the structure of a real mobile robot system is established to implement in the simulation. The simulation results demonstrate the effectiveness of the proposed approach for identifying the mobile robot dynamic parameters.
