Perancangan Prototype Troli Pengangkut Barang Otomatis Mengikuti Pergerakan Manusia

Abstract

The Prototype of an automatic trolley that follows the movement of human is a robot that serves as a trolley to bring shopping goods that follow humans automatically, without the need to be pushed or pulled, so this movement can ease humans for shopping. The trolley prototype has the ability to detect the presence of users and follow the direction of user movement. The trolley prototype control uses the Arduino Uno microcontroller minimum system, by detecting the user's position using the Ultrasonic sensor. The trolley prototype is powered by 4 DC motors and the power source of a battery that has 9V DC power. The maximum load of this prototype carrying capacity is 1 Kg. The trolley prototype capability detects the user's motion direction is limited to a distance of 200 cm. This prototype control is able to adjust the movement and can stop, turn following the direction of the user, backward and forward which depends on the distance between the prototype of the trolley and the user.
