Published: July 2023

Mobile robot line follower is still a very popular research topic. Line follower robots are the basis for developing robot applications in various fields. The key to a robot's success is being able to read and follow lines precisely and quickly. Many control system methods have been developed to improve the robot's ability to follow the line. Several methods including PID and Fuzzy which have been widely studied. Even though it is supported by the control method there is one problem that affects the robot navigation system, namely the power supply voltage. The robot's power supply is usually sourced from a battery which within a certain usage period will decrease. When the power supply is reduced, the robot's navigation system will also have problems, whether it is getting slower or the robot becomes zig-zag. When the power supply voltage is fully charged, the DC motor will tend to be fast and conversely, when the power supply voltage drops, the DC motor will run slower. The results of testing the effect of the power supply voltage on the speed of robot navigation show that in the power supply range of 8.44V to 6V the best speed is obtained at a voltage of 7.2V.
