AUTOMATIC PNEUMATIC GLASS WALL CLIMBING ROBOT

Abstract

Most of heavy Architectural structures today were built with glass fabrication, for the aesthetic looks. Due to present environmental conditions, those structures were filled with dust which became very difficult to clean manually. By using robotic technology most of the systems were developed for the same purpose, which were failed to reach elevated highly due to heavy body. In this project an automatic wall climbing robot was developed using the concept of pneumatics and programmable logic controller. Two pneumatic cylinders were used for the movement of up &down and right & left for wall gripping and the robot suction cups were provided on all sides of robot. The sequencing of the pneumatic cylinders pressure cups solenoid operated direction control valves which are further controlled by using a ladder logic in PLC. The sensors were provided on 4 sides of the robot for detecting obstacles such that it can automatically change the direction of movement. The size and weight of the robot was reduced by using minimum number of components in the system, which are necessary for efficient running of the robot and feasibility of vertical transportation
