The recent trends in the field of Robotics have evolved a lot irrespective of its application across any field. That too when wall climbing robots are considered, many researchers have come up with many innovative designs considering environmental constraints. These wall climbing robots have many industrial applications. The two major design constraints of any wall climbing robot would be this payload and self-weight of the robot. A wall climbing robot with high payload with low self-weight would be preferable for better efficient application. Though there are many designs available, the most effective and inspiring design would be the bio-inspired hexapod robots shaped wall climbing robots. Hexapod robots mean robot having six legs for its locomotion. Many researchers have proposed their own design with their own way of actuation method, stability factor and trajectory planning method. Some researchers have used software simulation tool like MATLAB, Solid Works, CATIA etc., instead of hardware modelling. In order to propose an innovative hexapod robot’s wall climbing robots design, it is essential to understand the existing design proposed by various researchers particularly on this design of hexapod robots in this article, a comparison is made by visualizing these proposed models and their unique design for hexapod robots. A deep survey is made on the existing design of hexapod robot’s wall climbing robot and hexapod robots with respect to its payload (p) and self-weight (w) capacity. The article also enables to understand the maximum PWR value achieved so far with this existing design of hexapod robot.
