Abstract

Inclination is the angle formed by tilt angle to vertical line. This research determine the effect of tilt angle to the performance of the device, changes the quality, affordability and stability of connections. In addition, this research also presented the comparative performance of the device after tilt angle changed  and  find  the optimal angle. This research, explained  the change in  angle of inclination generally affected the main lobe and back lobe in the antenna’s beam of NanoStation2 Loco. Inclination angle also causes the signal strength and connection stability affected, especially on devices at distance over 100 m from the antenna. This research made changes three times to the antenna’s tilt. There are 10 °, 20 ° and 30 °. From the angle change, the result indicates that the most effective use of research sites of the Faculty of Engineering, University Tanjungpura Pontianak is tilted at angle of 20°. This is proved by results of measuring Received Signal Strength Indicator and Packet Loss that be the main indicator to determine the quality of the antenna. From the data showed the measurement of signal strength under -90 dBm at distance over 100 m will lead the connection and stability to be poor connection. This situation is shown by the high number percentage of packet loss that occurs during pingtest. At the point of measurement locations under 100 m and minimum obstacle, change angles do not have a big impact and quality of the antenna is in excellent. In addition to the distance from the antenna, the obstacle factors (barriers of the building) is also a big influence on the quality of the antenna.

Abstract

Teknologi robot mengalami suatu kemajuan yang sangat pesat pada saat ini. Robot yang canggih telah menggantikan peralatan-peralatan manual yang membutuhkan banyak tenaga manusia, salah satunya yaitu penggunaan robot lengan. Robot lengan yang dibuat ini merupakan bagian dari robot dengan skala prototype untuk kegiatan praktikum yang dapat menggantikan maupun meringankan kerja manusia secara langsung. Dalam kenyataannya sering didapatkan kendala bagaimana cara mengontrol atau mengendalikan suatu alat dengan mudah untuk diopersikan. Dalam tugas akhir ini dirancang sebuah robot lengan 4 DOF (Degree Of Freedom) yang memiliki sistem yang mudah dikendalikan berupa sistem robot lengan yang secara keseluruhan dikendalikan melalui aplikasi interface dengan GUI (Graphical User Interface) yang dibangun dengan bahasa pemrograman Java pada PC (Personal Computer). Mikrokontroler Arduino Uno sebagai pengendali utama yang terkoneksi via USB (Universal Serial Bus) dengan PC. Pada komunikasi interface antara aplikasi program pengendali dengan mikrokontroler Arduino Uno terjadi proses pengiriman (Tx) dan penerima (Rx) data serial yang berupa data byte. Data byte yang dikirim oleh slider pengendali akan menentukan lebar pulsa sinyal PWM (Pulse Width Modulation) pada setiap motor servo sehingga pergerakan robot sesuai dengan pergeseran slider. Program aplikasi slider pengendali ini memiliki dua mode, yaitu mode kendali per-slider dan mode kendali sekaligus kirim. Berdasarkan hasil pengujian sinkronisasi gerak antara robot lengan dan slider pengendali didapatkan hasil bahwa semakin besar nilai derajat pergeseran slider maka lebar pulsa sinyal PWM semakin melebar dan tegangan keluaran dari pin mikrokontroler Arduino Uno semakin besar dengan nilai rata-rata tegangan yang dihasilkan sebesar 115,03 mV. Robot dalam keadaan standby hanya membutuhkan daya sebesar 0,9 Watt dan saat beroperasi membutuhkan daya sebesar 3,94 Watt. Nilai rata-rata sudut dan selisih sudut ideal dengan yang dihasilkan base yaitu 97,17° dengan selisih 7,17°, link 1 yaitu 73,64° dengan selisih 3,64°, link 2 yaitu 90,24° dengan selisih 0,24°, link 3 yaitu 96,8° dengan selisih 6,8° dan end-effector sesuai perancangan dengan selisih 0. Sudut yang terbentuk dari manipulator robot hanya hampir mendekati sudut yang sebenarnya dikehendaki (sudut ideal) dikarenakan permasalahan dalam perancangan serta pembuatan mekaniknya. Penulis memberikan pembatasan rentang slider pengendali agar mekanik robot tidak patah dan menghindari kerusakan pada motor servo. Hasil pengujian menyimpulkan bahwa robot bisa bersinkronisasi dengan aplikasi pengendali serta dapat digunakan dalam kegiatan praktikum.   Kata kunci: robot lengan 4 DOF, mikrokontroler Arduino Uno, Arduino dengan Java
