The need for a non manual and affordable residential gate by both rich and middle-class populace has brought out the need for designing, constructing and testing for reliability a remote controlled residential sliding gate. The design principle entails effecting a sliding motion of the gate through a rack and pinion mechanism. A rack of the same length as the gate length was attached to the gate in mesh with a pinion powered by a D.C. 50W, 24V motor. Control sensors were connected for remote control operation and detection of the terminal points of gate movement. The gate is of length 3.04m by 1.4m covered with aluminium sheet of thickness 0.2mm. The gear pinion and gate track roller diameter were 61mm and 100mm. The weight of the gate was made variable by attachments of known weight falling within 40 Kg to 80 Kg. Support guide made of low carbon steel pipe of square section 50mm was used to hold the gate in an upright position. Four rollers made of medium carbon steel was welded to the gate to aid the movement of the gate on the rail track which comprised of two angle bars formed into T shape. Operational performance tests showed a maximum opening velocity of 0.21m/s to 0.15m/s corresponding to gate weights 40 to 80kg respectively. Rolling track friction also affects velocity of the gate. The lubricated track indicated higher velocity than the dry track
