Designing Prototype of Follow Me Robots to Help Lift Loads of Goods Based On Ultrasonic Sensor

Abstract

The rapid development of technology makes tools that were previously driven manually can now move automatically. One example is “Cowarobot R1” a suitcase that can follow its owner. In the prototype robot follow me research was made to relieve humans in carrying goods. This prototype works by utilizing ultrasonic sensors and infrared sensors. The HC-SR04 ultrasonic sensor works as a distance detection object, where in this prototype the maximum distance that can be processed as far as 40 cm with a diffraction angle of 25°. While the infrared sensor is used for object detection, where this prototype will follow the object that has been implanted infrared transmitter. The travel time needed for this prototype before adding a load of 1.85 s with a speed of 0.54 m / s to move. Whereas after being given a 500 g load the resulting travel time became 3.55 s with a speed of 0.28 m /s.
