Abstract

Robot EMoRo edukacijski je robot čija se primjena vidi u automatici, robotici i informatici. Njegovo programiranje temelji se na Arduinu i nije komplicirano za početnike. Njegova je funkcija slijediti liniju te nakon toga ući u sobu koja je veličine 120x90 cm i detektirati lopticu. Slijeđenje linije izvršeno je pomoću infracrvenih senzora koji očitavaju bijelo ili crno te za bijelo daju vrijednost '1', a za crno '0'. Ako oba očitaju stanje '1', nalaze se na bijeloj podlozi i trebaju voziti ravno, ako jedan od njih očita '0', robot treba skrenuti na tu stranu s koje je crna očitana. No ako oba očitaju '0', robot se treba zaustaviti. Za detekciju loptice korišteno je sedam ultrazvučnih senzora i svaki je od njih postavljen tako da se usporedbom dvaju senzora može vidjeti razlika između zida i loptice. Ako je loptica očitana, robot treba biti usmjeren prema njoj i potom se zaustaviti pred njom.

Abstract (english)

The EMoRo robot is an educational robot whose application can be seen in automatics, robotics and informatics. Its programming is based on Arduino and is not complicated for beginners. Its function is to follow a line and enter a room that is 120 x 90 cm in size, and then find the ball inside. The line-following is executed by infrared sensors that can detect white and black surfaces. For a white surface, the sensors returns a value of '1', and for a black one, a value of '0'. If both sensors read '1', the robot is on the white surface and should drive forward, but if one of them reads '0', the robot should turn to the side where '0' was read. If both sensors read a value of '0', the robot should stop. Seven ultrasonic sensors were used for the ball detection. Every one of them is placed so that comparing two sensors results in recognizing the difference between the wall and the ball. If the ball is found, the robot should be directed towards it and then stop in front of it.
