Pantography Application With Real-Time PLC Based on Image Processing in Gantry Robot System

Abstract

Programmable Logic Controllers (PLC) is one of the indispensable products of automation industry. PLCs, which are widely used in many fields of programming, make our lives easier in daily life. In this study, after determining the coordinates of the image taken from the camera with the help of image processing algorithm, the servo drives of cartesian machine are controlled and processed in X-Y plane with Rexroth PLC in real time. In this application, it is aimed to obtain the image again by subtracting the boundary coordinates of the image taken with the camera in MatLab environment. To achieve this goal, the servo drives of the cartesian machine were controlled and the application was realized. Two different methods were applied for the image taken in Matlab environment. The skeleton of the image was taken for the first method and then the boundary coordinates were determined. For the second method, the contour of the image was first extracted. The coordinates of the contour image were not directly used. These coordinates have been tried to be optimized. In this study, it is aimed to draw a desired image by drawing border coordinates in Matlab with Rexroth PLC on a cartesian machine. As a result of the test studies, it was seen that the drawing process was carried out properly (according to the coordinates received) as a result of the analysis and measurement processes (metric caliper and measurement methods).

Investigation of the Current and Voltage Waveforms for a TiO2-based Memristor with MATLAB

“…MATLAB can be considered as a key program for behavior analysis in Memristor devices. This program can be used for other areas including the low power and high power applications in electrical and electronics engineering [12][13][14][15]. In this section for the mentioned doped (TiO2) and undoped (Ti) blocks, different types of the input voltages under Memristor Parameters: Ron = 100, Ro = 4k condition are given are results are reported.…”

Kameradan Alınan Görüntünün CNC Tezgâhında Gerçek Zamanlı Olarak İşlenmesi

“…Elde edilen koordinatların CNC'de hareket yörüngesinde kullanabilmek için filtreden geçirmek gerekiyor. Çünkü özellikle doğru parçalarının çiziminde başlangıç ve bitiş olmak üzere iki koordinat değeri yeterli olurken matlab de bu koordinat değerleri görüntünün format özelliğine göre tüm piksel değerlerini hareket yörünge koordinatları olarak vermektedir [17][18]. Bu da CNC'de aşırı bellek ihtiyacını oluşturuyor.…”
