Günümüzde birçok alanda olduğu gibi, elektronik ve robotik sistemlerinde de ciddi kazanımlar elde edilmiş ve gündelik hayatımızın vazgeçilmezleri arasına girmiştir. Daha önemlisi, önceleri belli amaçlar için üretilen bilgisayarlar günümüzde genel amaçlı mikro bilgisayarlar şeklinde üretilip satılmaya başlanmıştır. Bu sayede, farklı sistemlerin sadece firmalar tarafından değil, bireysel geliştiriciler tarafından da tasarlanmasına katkı sağlamıştır. Bu bağlamda insanların kendilerine özgü sistemler geliştirmesine, hem daha az maliyetli hem de daha küçük yapıda ürünlerin tasarlanmasına yardımcı olmaktadır. Bu çalışmada genel ağaç ve bitki ilaçlamasına yönelik, mobil örnek bir robot üretmek amaçlanmıştır. Robotun tüm tasarımı orijinal olup, endüstriyel ürünün fonksiyonel alt yapısı olarak geliştirilmiştir. Robotun hali hazırda görme becerisi sadece ilaçlanabilir veya ilaçlanamaz diye nesneleri ayırmakla sınırlı olsa da, uzun vadede farklı tarım ürünlerini algılayarak, uygun ilaçlama yapabilmesi arzulanmaktadır.

Abstract-Today, as in many places, electronic and robotic systems have gained significant progress and are among the indispensable parts of our everyday life. More importantly, today, computers manufactured for specific purposes have begun to be produced and sold in the form of general-purpose microcomputers. In this way, it contributed to make possible to the design of different systems not only by companies but also by individual developers. In this context, it helps people to design their own systems, and to design products that are both less costly and smaller. In this study, it is aimed to produce a mobile sample robot for general tree and plant spraying. The entire design of the robot is original and developed as a functional sub-structure of the industrial product. Although the robot is currently limited in the ability to see objects only in terms of being able to be sprayed or not to be sprayed, it is desired to perceive the different agricultural products in the long run and to be able to do appropriate spraying.

In recent years, it has been observed that it becomes time-consuming and cumbersome job to find a vacant parking lot, especially in urban areas. Thus, it makes difficult for potential visitors or customers to search a vacant space for parking their vehicles and keeps on revolving round the parking area which not only increases frustration level but also wastes time and energy. In order to get an optimal parking lot immediately, there is a requirement of an efficient car-park routing systems. Current systems detecting vacant parking lots are either based on very expensive sensor based technology; or based on video based technologies which do not consider various weather conditions like sunny, cloudy and rainy weather. In the proposed work, a hybrid model is designed for detecting outdoor parking which detects the empty spaces available in the parking lots and the spaces/slots getting vacant in the realtime scenario. This model is based on training, validating and testing the images (dataset) collected from various heights and angles of different parking areas stored in the repository. In this research, more advanced feature extractors and machine learning algorithms are evaluated in order to find the vacant parking lots in the outdoor parking areas.

Memristor-based hardware accelerators are gaining an increased attention as a potential candidate to speed-up the vector-matrix operations commonly needed in many digital image processing tasks due to their area, speed, and energy efficiency. In this paper, a memristor-based image compression (MR-IC) architecture that exploits a lossy 2-D discrete wavelet transform is proposed. The architecture is composed of a computational memristor crossbar, an intermediate memory array that stores the row-transformed coefficients and a final memory that holds the compressed version of the original image. The computational memristor array performs in-memory computation on the initially stored transformation coefficients. Using the quantitative analysis approach, we demonstrate a 10x reduction in a number of operations compared with a conventional application-specific integrated circuit implementation. This translates to five orders of magnitude reduction in area, around 11x improvement in energy efficiency, and 1.28x speedup in computation time. Image quality metrics, such as peak signal-to-noise ratio (PSNR), structural similarity (SSIM) index, and complex wavelet-SSIM (CW-SSIM), are used to quantify the reduction in image quality due to lossy compression. The achieved metrics for conventional versus MR-IC are: PSNR 57.24 versus 33.29 dB, SSIM 0.9994 versus 0.8853, and CW-SSIM 1 versus 0.9983. Simulation results show that the 32 quantization levels proposed architecture provides significant improvements in energy, area, and performance compared to the 32 levels CMOS implementation with comparable CW-SSIM.
