Design and Analysis of Wall-Climbing Robot

Abstract

A robot is a machine that can perform desired tasks with high accuracy and minimal human interference.Robots are employed to automate repetitive activities and work in unpredictable or hazardous environments.Depending upon the functionality, different types of robots, such as Automated Guided Vehicle, Articulated Robots, and Humanoids are developed.Wall-climbing robot is one which freely moves on surfaces like walls and ceilings.These are used in inspection and cleaning of walls.Design of wall-climbing robot deals in two aspectslocomotion mechanism, by using wheels and legs for mobility, and an adhesion mechanism to counter the force of gravity firmly with the help of vacuum suction or magnetic adhesion methods.The aim is to design a wall-climbing robot that travels on irregular surfaces.For achieving this, a Reverse Thrust and Wheeldriven type of robot was adopted.For climbing designer walls, the concept of hinges was used.Modelling and Simulation of the robot is done using SolidWorks software and performed the CFD analysis of the ducted fan using ANSYS Fluent.
