    Development of a Novel Spherical Light-Based Positioning Sensor in Solar Tracking
    (MDPI, 2023) Oguz Gora; Taner Akkan; Gora, Oğuz; Akkan, Taner
    Tracking of the sun which increases the efficiency of solar energy production systems has shown considerable development in recent years. This development has been achieved by custom-positioned light sensors image cameras sensorless chronological systems and intelligent controller supported systems or by synergetic use of these systems. This study contributes to this research area with a novel spherical-based sensor which measures spherical light source emittance and localizes the light source. This sensor was built by using miniature light sensors placed on a spherical shaped three-dimensional printed body with data acquisition electronic circuitry. Besides the developed sensor data acquisition embedded software preprocessing and filtering processes were conducted on these measured data. In the study the outputs of Moving Average Savitzky-Golay and Median filters were used for the localization of the light source. The center of gravity for each filter used was determined as a point and the location of the light source was determined. The spherical sensor system obtained by this study is applicable for various solar tracking methods. The approach of the study also shows that this measurement system is applicable for obtaining the position of local light sources such as the ones placed on mobile or cooperative robots.

    DÖRT ROTORLU UÇAN ROBOT DENGE VE YÖNELİM ANALİZİ İLE UYGULAMASI
    (2014) OĞUZ GORA; Taner AKKAN; Gora, Oğuz; Akkan, Taner
    Bu çalışma dört rotorlu uçan robotun kontrolünü dengesini ve yönelim açılarını incelemektedir. Dört rotorlu uçan robot için test platformu geliştirilmiş ve kullanılmıştır. Uçan robota harici takılan Ataletsel Ölçüm Birimi (AÖB) yardımıyla alınan oryantasyon verileri kablosuz olarak bilgisayara taşınmaktadır. Taşınan veriler Matlab ve Python programlama dillerinde analiz edilmektedir. Böylece sistemin kumandadan aldığı hareket komutlarını çalıştırırken gösterdiği gerçek zamanlı davranışlar analiz edilmektedir. Uygulama için dokuz serbestlik derecesine sahip bir oryantasyon sensörü Xbee Explorer modülleri Walkera Ufo 5# dört rotorlu uçan robotu kullanılmıştır. Çalışmada dört rotorlu uçan robotun aç/kapa kontrolü de başarıyla tamamlanmıştır.
