Rancang Bangun Robot Pengikut Garis Dan Pendeteksi Halangan Menggunakan Mikrokontroler AT89S51
ABSTRACT: Recently, the
electronic field develop rapidly especially in creating robotic. Many
competitions have conducted to compare technology, from hobbies until robotic
industries are never bored to talk. Industrially, automotive robotic needed in
order to make the work more efficient, then it save cost of a production.
Automotive robotic used also in entering dangerous area, that there is unable
to handle by human for safety reason.In this paper, there are two automotive
robotic that created, which able to follow line and stop when it detects any
obstruction at front side. This robotic designed by Microcontroller AT89551,
ultrasonic sensor as obstruction detector and
it also have four infrared and photodiode sensors as line detector which
through by feet. Automotive robotic will run following designed line, if there
is any obstruction then it will stop as long as those obstructions are there
and it run again if the ultrasonic sensor do not detect obstruction anymore. By
regulating PWM signal (Pulse Width Modulation) from microcontroller, then the
automotive robotic can walk straightly, turn and will stop if there are any
obstruction detected.From the experiment and test which performed, robot is able to pass the
turn with 60 cm of diameter, while for
movement fork it is only perform
straightly and stopped, exactly if robot finding the obstruction it can stoped
in the distance 40 cm. It shows that there is lack of sensor, which used in
designing, then for particular fork, robotic is only able to stop and walk
straightly.
