Modeling and control of unicycle type-robots in presence of decoupled slipping and skidding effects

Abstract

In this paper we are concerned with the control of unicycle-type wheeled mobile robots in presence of sliding effects. We elaborate two models for control purpose. In the first one, we take into account only the slipping effects. In the second model, we introduce only the skidding effects. For each model, we propose a robust control law against the sliding effects to solve a velocity tracking problem.
