In comparison with the majority of other animals, the spider can access all kinds of environments where other animals or even humans can't. These important attributes are taken into consideration, to design and develop a Hexapod Walking Robot, in order to perform various movements such as ascend and descend in all the directions. Hexapod Robots have always been a centre of attraction for several years. Many universities, research centres, and industries have carried out studies but in the past few years, systematic walking robots have been formulated, fabricated, and built with implementations that can be suitable for experimental demands. The paper presents a model to understand how, mathematically, a hexapod animal walk. The aim is to develop a suitable bio-mimetic model of hexapod walking robot that is lighter in weight with reduced number of motors and easily controllable. Modifications in the design is adopted by using solid works. Thereafter, a detailed analysis of the model is conducted along with the moment and force analysis. Moment analysis is carried out to check the walking capabilities of the legs at extreme joint positions. The robot leg motion is checked by applying loads at which the robot turns to fail and it has been found that the proposed model is suitable to bear different forces while walking to perform any desired task. This research also gives an outline of the design considerations of the Hexapod Walking Robot and a detailed design procedure is also discussed for the feasible and systematic design of a walking robot. In particular, these design procedures covers the main features such as mechanical structure and leg configuration, actuating and driving systems, motion controls, and walking gaits.
