A Novel Design Technique to Develop a Low Cost and Highly Stable Wall Climbing Robot

In this paper the proposed method aims to develop a low cost and efficient wall climbing robot that can climb on almost all surfaces. To ensure mechanical stability a centrifugal impeller is used and positioned above the robot that helps to generate an isolated low pressure area that makes adhesion to the vertical wall possible. When the impeller works, the sealing used in our robot reshapes to the shape of the contacting surface, maintaining the low pressure area inside which is a main advantage that eliminates the need for a perfect sealing as required by other vacuum powered wall climbing robots. To control the robot we use an ATmega8 micro controller along with RF wireless transceiver module and some discrete components. The experiment results verified the feasibility of the robot and it can make wall to floor and floor to wall transitions.
