Abstract
An analysis report compiled by the OSHA lists eighty-eight (88) window cleaning accidents over the past 15 years of which sixty-two (62) resulted in fatalities [1]. Despite these statistics and the potential for injuries and deaths, the industry considers these numbers to be artificially low. Window cleaning is still not effectively regulated, and numerous people undertake this activity in a way that endangers both themselves and the public. This project aims at removing the human component in this life-endangering task by building an autonomous window cleaning robot, The Wall-C, with the capability of scaling walls and skyscrapers with windows. The main task undertaken by this system is to efficiently clean windows on buildings such as glass skyscrapers while systematically moving from glass section to glass section. The focus of this paper though is the manufacturing processes undertaken in the creation of the Wall-C. These included the casting, finishing and assembly operations in bringing the skeletal frame of the window cleaning robot together. The weight of the Wall-C was recorded to be approximately 15 kg, and it had a cleaning rate of 6.156 m2/hr.
