Sky Cleaner 3: a real pneumatic climbing robot for glass-wall cleaning

There are large numbers of high-rise buildings with glass curtain walls that require constant cleaning and is carried out using permanent gondola systems. This is a laborious and dangerous work in midair. Due to a lack of uniform building structure, wall cleaning and maintenance of high-rise buildings is becoming one of the most appropriate fields for robotization. The development of walking and climbing offers a novel alternative solution to glass-wall cleaning. Application of a type of cleaning robotic system can free workers from this hazardous work and realize an automatic cleaning of high-rise buildings, thereby improving the technological level and productivity of the service industry.
