Inspired by macroscale vehicles, many molecular machines have been synthesized yet. Due to the importance of atomic manipulation, nanocars are of particular interest. It has been proven that nanocar wheels play a crucial role in their motion. One of the popular candidate for using as a nanocar wheel is fullerene. In addition the investigation of nanocar motion on two dimensional substrates is noteworthy influenced by surface ripple formation. Therefore, in this work we study fullerene particle motion on graphene and boron nitride monolayer substrates in a same temperature. All simulations are conducted by the means of molecular dynamic simulation method. Fullerene motion trajectory shows more displacement domain when fullerene is moving on the graphene surface and as a result, fullerene has a greater diffusion coefficient on graphene surface. It has been showed that C60 motion on graphene and boron nitride obey a same super-diffusion regime in 300 K with different anomaly parameters.
