BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art. [0003] With the development of the commercial economy and the continuous development of the market, there are more and more rolling doors are installed in the market such as in commercial buildings, shops, warehouses, garages, and other buildings. Rolling doors are made of horizontal slats of steel or aluminum that are hinged together. The rolling doors serve the dual purpose of increasing the aesthetic of homes, commercial buildings, shops and providing protection from vandalism and theft also.
[0004] The conventional rolling doors are hand driven i.e. manually operated and difficult to operate manually due to heavy weight and complexity. Hence, there is a requirement for controlling the rolling doors automatically. [0005] Other existing rolling shutters having a motor for automatic operation, but in case if the motor is not working due to some internal failure, the rolling doors cannot be opened or closed, and repairing is required which takes long time. Similarly, in case power supply is interrupted for a long time due to bad weather or transmitter breakdown, the rolling doors cannot be opened or closed, until power supply is provided, which also takes long time in some scenarios. [0006] There is a need to overcome above mentioned problems of prior art by bringing a solution that helps in opening and closing of rolling doors automatically, and in case of power failure or motor failure, the rolling doors can be opened manually by a user without affecting the existing assembly.
