Abstract The Bondsim library, that enables direct drawing the Matlab-Simulink block diagrams from the bond graphs is presented in this paper. Derivative Bondsim elements for I and C bond graph elements with derivative causalities are given in this paper. The extension of the bond graph theory for the modeling of nonlinear stochastic systems is introduces in this paper too. For that purpose the random Bondsim elements are presented. The application of the Bondsim elements on the example of hydraulic robot is also given in this paper. References P. J. Gawthrop and L.
