This project presents the kinematics of the movement of a mobile six-legged robot, inspired by the living world, as well as the command and control system, which allow the robot to move on different surfaces with different speeds. In order to generate the movement, through a control and control system, stepper motors and bars are used. A frame, connecting rod, crank and a lever constitute to obtain the required movement. In this project the application of a simple mechanism of four bars is used. The most important benefit of this mechanism is that it does not require microprocessor, controller and other drive mechanisms. Armed forces, law enforcement, explosive ordnance units and private security companies could also benefit from the applications of this mechanism. It would work very well as a platform with the ability to handle ladders and other obstacles better than wheeled vehicles or tracking. In this mechanism, the links are connected by pivot joints and convert the rotational movement of the crank to the movement of the foot similar to that of the animal's gait. The mechanisms for walking are developed by imitating nature as the movement of insects. Nature inspired researchers and new innovative ideas come in mind but sometimes they are simple and effective, sometimes uncomfortable and critical. One of the first walking machines was developed in 1870 by the Russian mathematician Chebyshev.
This walking machine had four legs arranged in pairs. The machines with legs have been used for at least a hundred years and are superior to the wheels. The locomotion with legs must be mechanically superior to the locomotive with wheels or located on a variety of ground conditions and certainly superior for crossing obstacles. US Army research reports that about half of the land surface is inaccessible to wheeled vehicles, while this terrain is mostly exploited by animals with legs. Robots with wheels are the simplest and cheapest robots are also very good to move, but not on almost all types of terrain. There are different types of walking robots with legs. They are divided into groups according to the number of legs they have. The bipeds have two legs, quadrupeds four, six hexapods and octopods have eight legs. Bipeds "are dynamically stable, but statically unstable, such robots are more difficult to balance, and dynamic equilibrium can only be achieved while walking. Hexapods are six-legged robots, on the contrary, they have the advantages of being statically stable. During the march they can move three legs at a time, thus leaving three other legs always on the ground forming a triangle.
