Design and Implementation of Semi-Autonomous Wall Climbing Robot Using Vacuum Suction Adhesion

This paper presents the wirelessly operated semi-independent wall climbing robot, capable of climbing vertical surfaces and ceilings. To increase the working efficiency and to save human life, the robot was designed. For the movement of the robot, a method of a centrifugal pump for continuous suction is utilized. Detailed analysis and scientific calculations are performed for the mechanical design of the robot. The design of the robot is unique and having a high degree of modification makes it suitable for different applications. All mechanical design parts of the robot are manufactured after complete study, including basic structure, the vacuum duct, driving assembly, and the camera mounting pad. The wireless transceiver is employed to control the robot and to transmit wireless video signal captured by the camera. This robot overcomes the design limitations of certain other prototypes. The robot could be used for inspection, surveillance and could provide information in hostage situations. The robot is overall lightweight and smaller in size.
