Minérographie. Minéraux. Formation et gisements de minerais Résumé : In this paper, a refined control model for a Mecanum-wheeled mobile robot is developed and presented. Available control models in literature for Mecanum-wheeled mobile robots are based on a simplification which defines the contact point of the wheel on the ground as the point in the center of the wheel, which does not vary. This limits the smoothness of motion of a mobile robot employing these wheels and impacts the efficiency of locomotion of mobile robots using Mecanum wheels. The control model proposed in this paper accounts for the fact that the contact point in fact changes position down the axle of the wheel as the angle roller moves on the ground. The developed control model is verified with experimental results. Using the refined model, control of Mecanum-wheeled mobile robot is made more predictable and accurate.
