Robot line follower merupakan robot yang dirancang untuk membantu pekerjaan manusia. Pada penelitian ini, robot line follower yang dibangun terdiri dari 8 sensor pembaca garis, dan menggunakan Arduino Mega 2560, aktuator motor servo continous dan pensuplaian yang berasal dari sel surya. Sel surya yang digunakan adalah jenis polycrystalline dengan kapasitas daya sebesar 20W. Berdasarkan hasil pengujian penggunaan catu daya dari sel surya, menunjukkan bahwa nilai intensitas cahaya matahari yang didapatkan adalah rata-rata antara 48.940 lux dan 55.453 lux. Kemudian jika nilai intensitas cahaya matahari didapati dibawah 15.000 lux maka robot line follower tidak mampu untuk bergerak karena nilai intensitas cahaya matahari yang diterima mesti berkisar antara 40.000 - 83.000 lux.

Revolusi industri telah mengubah kehidupan manusia dengan dramatis dan teknologi menyentuh semua asfek kehidupan manusia. Teknologi otomasi yang pada awal kemunculannya hanya di industri, kini telah merambah semua lini kehidupan. Robotika adalah bentuk dari teknologi otomasi tersebut, dan dengan penurunan harga komponen, semua orang bisa membangun robot untuk kebutuhan masing-masing. Salah satu aplikasi teknologi robot adalah robot pengikut manusia yang dapat berfungsi sebagai pengangkut barang, sehingga manusia tidak perlu membawa-bawa barang yang diperlukan, cukup dengan membiarkan robot mengikutinya sesuai dengan kebutuhan. Robot pengikut manusia pada paper ini adalah prototype robot yang terbuat dari mobile robot sederhana yang dilengkapi dengan 2 sensor jarak untuk mendeteksi keberadaan manusia, dan robot bergerak sesuai jarak dengan manusia tersebut. Robot akan mengikuti manusia dengan kecepatan yang tetap pada saat jarak > 15 cm dan < 30 cm. Jika jarak < 15 cm, robot akan berhenti, dan jika jarak >30 robot akan melaju mengejar manusia.

Air mempunyai peranan penting dalam proses produksi suatu industri farmasi. maka diperlukan penyediaan air bersih yang memenuhi standar dan kebutuhan industri yang berlaku secara kualitas, kuantitas, dan kontinuitas, agar proses produksi dapat berjalan dengan baik. Di perusahaan farmasi seperti di PT. Dexa Medica Palembang terdapat beberapa tingkatan air untuk farmasi yang bervariasi tergantung dari tujuan pemakaiannya yaitu Raw water, Filter water, Purified water, dan Water for injection. Proses penyimpanan untuk air Raw water dan Filter water cukup disimpan di dalam tanki tanpa mengalami proses lebih lanjut, sedangkan Purified water harus disimpan dan diputar dengan mekanisme loop system sebelum didistribusikan. Secara periodik air didalam tanki penyimpanan purified water harus dipanaskan dengan temperatur lebih dari 70oC selama tidak kurang dari 3 jam (parameter ini perlu divalidasi tergantung system pendistribusian dan looping system yang dipakai). Maka digunakanlah looping water untuk menjaga suhu air pada kondisi auto pada suhu 37oC dan pada kondisi sanitasi pada suhu 70 oC dengan level air dijaga pada level 89.99%.

Arm robot manipulator adalah jenis robot yang paling banyak digunakan, dan bagian terpenting dari arm robot manipulator ini adalah end-effector. Walaupun pada banyak aplikasi di industri, end-effector dibuat sesederhana mungkin, pada beberapa aplikasi seperti prosthetic arm diperlukan end-effector yang menyerupai tangan manusia. Paper ini membahas perbandingan desain dan pemodelan tangan robot 5 jari, mulai dari penurunan model kinematis sampai pemilihan sistem kendali yang paling tepat untuk mengatasi batasan underactuated system. Dari studi literatur ini, dapat dilihat model kinematis sangat penting untuk mendapatkan persamaan yang paling mendekati sistem mekanis yang ada dan untuk kemudian akan mendapatkan desain sistem kendali yang paling tepat. Untuk mengatasi batasan underactuated system, maka digunakan penggerak pasif seperti spring, oleh karena itu pengaplikasian Impedance Control adalah paling tepat dengan menggunakan tambahan spring damper virtual.

Mobile robot are widely applied in various aspect of human life. The main issue of this type of robot is how to navigate safely to reach the goal or finish the assigned task when applied autonomously in dynamic and uncertain environment. The ap- plication of artificial intelligence, namely neural network, can provide a ”brain” for the robot to navigate safely in completing the assigned task. By applying neural network, the complexity of mobile robot control can be reduced by choosing the right model of the system, either from mathematical modeling or directly taken from the input of sensory data information. In this study, we compare the presented methods of previous researches that applies neural network to mobile robot navigation. The comparison is started by considering the right mathematical model for the robot, getting the Jacobian matrix for online training, and giving the achieved input model to the designed neural network layers in order to get the estimated position of the robot. From this literature study, it is concluded that the consideration of both kinematics and dynamics modeling of the robot will result in better performance since the exact parameters of the system are known.

Mobile robots are applied everywhere in the human's life, starting from industries to domestics. This phenomenon makes it one of the most studied subjects in electronics engineering. Navigation is always an issue for this kind of robot, to ensure it can finish its task safely. Giving it a “brain” is one of the ways to create an autonomous navigating robot. The Fuzzy logic controller is a good choice for the “brain” since it does not need accurate mathematical modeling of the system. Only by utilizing the inputs from sensors are enough to design an effective controller. This paper presents an FLC design for leader-follower robot. This FLC design is the improvement of FLC application in a single two differential-driven mobile robot. The relation between leader and follower robot is modeled linearly as a spring-damper system. Simulation proves the feasibility of the proposed method in several environment setting, and this paper also shows that the method can be easily extended to one leader and more than one follower's formation. The research in this paper has introduced in the classroom as the teaching-learning media to improve students' involvement and interest in robotics and robotics related class. This paper is also part of our campaign and encouragement for teachers and students to use low-cost and open source software since not all the universities in developing country can afford the expensive high-end software.

Arm robot manipulator heavily applied in industries ranging from welding, pick-and-place, assembly, packaging, labeling, etc. Trajectory planning and tracking is the fundamental design of an arm robot manipulator. The trajectory is set and determined to satisfy a certain criterion effectively and optimally. Optimization of robot trajectory is necessary to ensure the good quality product and to save energy, and this optimization can be provided by the right modeling and design. This paper presents a review study of arm-robot manipulator design and control for trajectory tracking by investigating the modeling of an arm robot manipulator starting from kinematics, dynamics and the application of the more advanced methods. The idea of this paper comes from the popularity of inverse kinematics among students.

As robots' use increases in every sector of human life, the demand for cheap and efficient robots has also enlarged. The use of two or more simple robot is preferable to the use of one sophisticated robot. The agriculture industry can benefit from installing a robot, from seeding to the packaging of the product. A precise analysis is required for the installation of two collaborative robots. This paper discusses the motion control analysis of two collaborative arms robots in the fruit packaging system. The study begins with the relative motion analysis between two robots, starting with kinematics modeling, image processing for object detection, and the Fuzzy Logic Controller's design to show the relationship between the robot inputs and outputs. The analysis is carried out using SCILAB, open-source software for numerical computing engineering. This paper is intended as the initial analysis of the feasibility of the real experimental system.
