The engineering building of the University Leicester built-in 1963 has been a British icon for decades now. Applications of Robotic technologies are uprising nowadays, which provides a contingency to manipulate the benefits of robotics for executing challenging and precarious facade cleaning processes. This paper surveys the facade cleaning robotic technologies exist in the market. It exhibits the comparative analysis of four notorious robotic facade cleaning solutions namely Sky Pro, Gekko, BFMR (Building Façade Maintenance Robot) and Sirius_c. The comparison is executed using Multi Criteria Decision Analysis (MCDA) and Quality Function Deployment (QFD) techniques. This study analyses the performance of the robots based on the critical parameters such as water consumption, cleaning efficiency, cleaning dimensions and ease of implementation. Although none of these robotic solutions are implemented off the shelf, some adaptation on these solutions is necessary for the development of robotic techniques work successfully in real time. This paper proposes a hybrid robotic solution combining the vacuum pump adhesion and wheeled locomotion for the effective cleaning of the complex external building structure based on the MCDA and QFD analysis. It highlights the significant future research directions in this field.

Climbing Robot Modelling Based on Grab Claws

Though the wall-climbing robots have be used extensively, however, no effective adhesion system has been designed for robots deployed in high-altitude, rough concrete buildings that are subjected to large wind loads and vibrations. Therefore, an initial design of a wall-climbing robot based on grab claw is presented and a climbing model is proposed in the paper. The mathematical model is established to reflect the relations between sharp hook and the micro-protuberance on the rough wall surface The stress on the hook-like claws is analyzed under three different conditions, so the steady grasping condition of the hook-like claws is obtained. Simulation results are carried out which demonstrates the stability of the grasping. Finally, the system outline and field implement scheme are presented.

W artykule przedstawiono projekt wspinającego się robota, opartego na chwytaku w postaci pazura. Zaproponowano także matematyczny model wspinania, pozwalający określić wpływ mikro-fałd na powierzchni pionowej na możliwość chwytania hakiem. Przeanalizowano możliwości obciążenia haka w trzech różnych warunkach pracy. Przeprowadzono badania symulacyjne i eksperymentalne w celu weryfikacji modelu.
