Snake robots are designed to safely perform the tasks that aren't easily done by Humans. There are many applications of Snake robots like Laser cutting from performing surgery to inspection. And also in rescue operations. During the last decade to now, the published literature of Snake robots has been increased vastly. However, no review has done on the locomotion of a Snake Robot using FPGA. The purpose of this paper is to give such review has been widely studied in the past several decades by lots of researchers. In this paper, we survey and discuss the state of the art, challenges, and possibilities of perception-driven obstacle-aided locomotion for snake robots. According to that obstacle, the action is taken on that obstacle by snake robot and how it destroys it. The project is developed by choosing software which we have chosen is Xilinx ISE10.4 environment using verilog and synthesized on FPGA part Spartan3AN board. Xilinx is a powerful software tool that is used to design, synthesize, simulate, test and verify digital circuit designs.
