In order to improve the cleaning efficiency of curtain wall, a pneumatic robot is designed. The robot is consists of mobile system, adsorption system and cleaning system. The mobile system is a cross-shaped framework that is driven by the pneumatic system and moves mutually. Vacuum sucker scheme is adopted in the adsorption system. Cleaning brush is driven directly backward and forward by the cylinder. The adsorption and detachment of robot feet sucker, body movement and sequence control of the robot cleaning task are controlled by the PLC. The function that robot can clean glass curtain wall efficiently by the harmony operation is achieved.
