Wheeled mobile robots (WMR) belong to the class of coupled mechanical systems with rolling kinematic constraints linear in the generalized velocities. In order to derive the mathematical model of this class of robots, we outline first the analysis of mechanical systems with such constraints using a Lagrangian formulation. In the process of constraint-force elimination and dimension-reduction, a matrix that appears to play a relevant role arises. We call it the holonomy matrix. It is shown that necessary and sufficient conditions for the integrability of the constraints are readily derived using the holonomy matrix. In the same vein, a class of nonholonomic systems is identified that is termed quasiholonomic, their Lagrange equations being f...
