Programiranje robota u javi
(primjer)

Primjer programa da se robot okreće u jednu stranu, pa u
drugu, oko istog kotača

•Pomoću ove naredbe uvozimo klase koje nisu definirane u programu
•Uzmimo primjer com.ridgesoft.robotics.Motor; gdje je
com.ridgesoft.robotics ime „biblioteke” gdje se željena klasa nalazi,
a Motor klasa koju želimo uvesti

try {
Motor motor = IntelliBrain.getMotor(1);

main
•Glavna funkcija u programu koja će se izvršiti kada se program
pokrene

import com.ridgesoft.robotics.Motor;
public class IntelliBrainMotor {
public static void main(String args[]) {

try {
Motor motor = IntelliBrain.getMotor(1);

}

try
•Naredba za „hvatanje” grešaka u kôd-u
•Ako se dogodi greška program prelazi na izvršavanje naredbi ispod
naredbe „catch”
catch
•U paru zagrada ( i ) zadajemo varijablu u koju će program zapisati
greške, a između zagrada { i } navodimo što želimo raditi sa tim
podatcima o greškama (ispisati ih na ekran itd...)
Throwable t
•Zadali smo varijablu „t” koja je definirana klasom Throwable. Ta klasa
nam omogućuje memoriranje svih vrsti grešaka (postoje i druge klase
za memoriranje grešaka). U varijablu „t” će program zapisati sve
greške u slučaju da se dogode
t.printStackTrace();
•Ovom naredbom ispisujemo na ekran sve greške koje je program
memorirao u varijablu „t”

Motor motor = IntelliBrain.getMotor(1);
•Definiramo varijablu motor klase Motor i pridjeljujemo joj motor koji
ima ID 1
setPower(...);
•Zadajemo motoru broj okretaja
Thread.sleep(...);
•Govorimo programu da napravi pauzu (u tisućinkama)
