This project presents a selfopening and closing door system based on human motion near the door. Over the years, the use of manually operated doors have shown some of the challenges associated with manual doors. Some of these challenges and limitations are; the difficulties encountered by physically challenged persons when trying to use manually operated doors, the risk of cross contamination due to physical contact between the door and the persons using the door, the cost of hiring persons in charge of opening doors for clients in commercial buildings, reduction in the rate of human and goods movement in work places due to obstruction to movement by manual doors, the problem of keeping the air condition in a public building (such as office, theater, shopping complex, etc.) intact. These challenges necessitate the design and fabrication of a door system that is capable of opening and closing on its own. The use of selfopening and closing door can be used to solve most of Thee challenges associated with manually operated doors. Self opening and closing door was designed and fabricated using locally sourced materials. The self opening and closing sliding door was tested after fabrication. The system functioned properly as desired. The design values of the design parameters were compared with the actual values measured from the system while in operation. The percentage deviation of the actual values from the design values of the design parameters such as door opening time, door delay time, door maximum velocity, door minimum velocity, and the total time taken for the door to complete one operational cycle are 7.69 %, 3.15%, 3.53%, 14.89%, and 6.51%. From the comparison, it was found out that the deviations of the actual value s from the design values were negligible. Thus, the system, self opening and closing sliding door, was functioning well.
