There is a need to achieve a capability for detailed modeling of the physical processes nano-robots at nano-scales that is driven by the growing demands of nanotechnology.. This is regime where behavior runs contrary to the familiar macroscopic world; optimized engineering design may well benefit from insight gained by emulating some of the multitude of architectures and mechanisms to be found in the biological world. Despite the fact that micro-robotics has long captured the imagination, practical implementations are only now starting to become feasible. One class of nano-robot with potential medical applications was considered that made of single wall carbon nanotube; however, long before... 

With the rapid progress of technology, the fabrication of smaller electronic and mechanical systems becomes more necessary. To make a small-scale system with better performance, one way is to create it from molecular components. In recent decade, many attempts have been devoted to the fabrication of molecular machines for manipulation of particles at nanoscales. In this project, the motion of two of most basic nanocars namely the Nanocar and the Nanotruck were simulated on gold and silver substrate at different conditions, both of four wheels and the nanotruck chassis is flexible. In the first chapter of this report, some of the most important natural and artificial machines are mentioned...
