A Stabilized Battery Power Source for a Robot That is Playing Robot Soccer

U ovom radu prikazan je postupak izrade napajanja za robota koji igra robotski nogomet s ciljem da se projektira robot koji zadovoljava uvjete RobboCup-a. Napajanje za robota sastoji se od 5V napajanja za mikrokontroler, promjenjivog napajanja za motore kojeg korisnik može podesiti i testera baterije. Napajanja su ostvarena uz pomoć regulatora napona LM7805 i LM317. Tester baterije koristi 4 komparatora unutar jednog integriranog kruga (LM339N) i daje signal stanja kapaciteta baterije pomoću LEDica. Napajanje koristi litijevu bateriju čije karakteristike i usporedbe s ostalim baterijama su objašnjene u radu.This final thesis shows a process of creating the power supply for a robot that plays robot football with the aim of designing a robot that meets the requirements of RobboCup. The power supply module for the robot is comprised of the 5V stabilized power for the microcontroller, of the variable user-adjustable power for the motors, and of the battery tester. The power supply is realized using LM7805 voltage regulators and LM317 chip. The battery tester uses four comparators within one integrated circuit (LM339N) and indicates the battery capacity status signal using LEDs. The power supply uses a lithium battery whose characteristics and comparisons with other batteries are explained in the work
