Automatic monorail control

Artikel ini pernah ikut lomba arduino Distrelec dan mendapat juara 3.
automatic monorail control

sebelumnya kita sudah memiliki kotak pengangkut robot. Robot ini berfungsi untuk mengantarkan kotak ke masing-masing stasiun yang telah ditentukan berdasarkan kertas di dalam kotak. untuk mengirim kotak ke tujuan, operator harus menekan tombol berdasarkan data di kertas. tetapi pada kenyataannya, operator sering salah menekan tombol dan akhirnya kotak dikirim ke tujuan yang salah. jadi kami memodifikasi tombol ini menggunakan arduino uno.
Sekarang operator tidak perlu lagi menekan tombol untuk mengirim kotak, tetapi cukup pindai barcode yang ada di kertas dan program akan secara otomatis mengarahkan kotak ke tujuan yang tepat. sehingga operator dapat menghemat waktu dan mengurangi kesalahan manusia.
