Dalam hal mengecat tidak semua orang dapat melakukan pengecatan dengan sempurna, banyak hasil cat yang tidak merata atau lapisan yang terlalu tebal dan terlalu tipis. Tujuan penelitian ini adalah membuat sebuah alat yang membantu manusia untuk mengecat objek di permukaan datar secara otomatis. Komponen yang digunakan dalam penelitian ini yaitu motor DC PG28, sensor encoder, sensor limit switch dan PLC Omron CP1E-NA20DR-A. Alat ini bergerak berdasarkan sumbu x dan y yaitu bergerak ke atas-bawah dan ke kanan-kiri, kemudian untuk pengecatanya menggunakan roll cat. Setiap pergerakan alat di program menggunakan ladder diagram di software CX-Programmer. Untuk memonitor pergerakan mesin peneliti membuat HMI dari software CX-Designer. Pada pembuatan program ladder diagram peneliti menggunakan metode state diagram karena metode ini dapat menyusun program ladder dengan baik. Pengujian pembacaan RPM motor peneliti membandingkan data dari PLC dengan tachometer dan didapat error sebesar 0,52%. Pergerakan alat pada sumbu x didapat dengan mengendalikan pulsa putaran per rotasi yang terbaca 1380 pulsa per 10 cm oleh sensor encoder. Jarak 10 cm mengacu pada lebar dari roll cat yang dipakai. Kemudian dengan tegangan luar sebesar 12V didapat kecepatan maksimun pada motor DCPG28 sebesar 379 RPM.In the case of painting not everyone can paint perfectly, many paints are not evenly distributed or layers that are too thick and too thin. The purpose of this research is to create a tool that helps humans to paint objects on a flat surface automatically. The components used in this study are the PG28 DC motor, encoder sensor, limit switch sensor and PLC Omron CP1E-NA20DR-A. This tool moves based on the x and y axis that is moving up-down and right-left, then for painting using a paint roll. Every movement of tools in the program uses ladder diagrams in the CX-Programmer software. To monitor the movement of the engine the researcher made an HMI from the CX-Designer software. In making ladder diagram programs researchers use the state diagram method because this method can arrange ladder programs well. Testing the RPM reads the motorbike comparing the data from the PLC with the tachometer and obtained an error of 0.52%. The movement of the tool on the x-axis is obtained by controlling the rotational pulses per rotation which reads 1380 pulses per 10 cm by the encoder sensor. A distance of 10 cm refers to the width of the paint roll used. Then with an outside voltage of 12V, the maximum speed of the DCPG28 motor is 379 RPM.

Aircraft System

Unmanned Aerial Vehicle (UAV) is an unmanned aircraft system that is no longer a special need but has become a general need for the community, and one example is used to capture everyday moments through photos or videos from the air. Among the models of UAV aircraft is the quadcopter, where there is a flight controller that functions to fly the quadcopter by adjusting the speed of each motor. The flight controller that is often used today is the Pixhawk manufacturer. The Pixhawk module is an integrated system that the factory has provided, so it cannot be modified in terms of control and I/O. This research focuses on making an independent flight controller that can be used to fly a quadcopter. The control method that is implanted is Proportional Integral Derivative or commonly known as PID. The flight controller uses the PID control method to adjust each Brushless DC Motor (BLDC) speed to maintain stability while flying. From the test results, the quadcopter can fly stably with KP parameters of 2.5, KI of 0.6, and KD of 1.0. The response time in processing feedback is 3s.

Measurable Factors

Analysing and optimising service productivity is a widely discussed task in service management. While directly measurable factors such as processing time or service turnover are frequently used in order to measure the productivity of services, underlying factors that are, in many cases, not (directly) measurable are not considered in-depth. However, these “qualitative” factors influence service productivity to a high degree. The idea behind the approach provided in this article is to open the former “black box” view on productivity (input–output) to a process efficiency-oriented perspective instead and to show which qualitative factors play a crucial role regarding service productivity.

The article describes concept and modelling of a new type of electrohydraulic valve controlled by the combination of a stepper motor and a DC motor. The aim of this invention is to use in the proportional valve two motors with the different properties. Both motors are responsible for the movement of a valve spool. The stepper motor and the DC motor are connected to a shaft by using a bellows coupling. Transfer from rotary to linear motion is performed by use of a bolt-nut system. According to the invention, presented here valve can be used in hydraulic drive systems with high positioning accuracy requirement. The author was granted a patent no.

The Given

We propose a technique for synthesizing bidirectional programs from the corresponding unidirectional code plus a few input/output examples. The core ideas are: (1) constructing a sketch using the given unidirectional program as a specification, and (2) filling the sketch in a modular fashion by exploiting the properties of bidirectional programs. These ideas are enabled by our choice of programming language, HOBiT, which is specifically designed to maintain the unidirectional program structure in bidirectional programming, and keep the parts that control bidirectional behavior modular. To evaluate our approach, we implemented it in a tool called Synbit and used it to generate bidirectional programs for intricate microbenchmarks, as well as for a few larger, more realistic problems. We also compared Synbit to a state-of-the-art unidirectional synthesis tool on the task of synthesizing backward computations.
