From an ecological perspective, increasing autonomy in subsea operations is vital for maintaining marine sustainability. These operations involve inspecting, maintaining, and repairing underwater equipment and structures, which can significantly impact the ecosystem if not carried out correctly. Using precise systems can reduce the risk of human error and minimize disturbance to the surrounding environment. This article presents an integrated head tracking system for ROV submarines, using a 3- dimensional orbiting...

Currently, the most common way of transporting medical products, such as blood, blood products, vaccines, and medicines, is air and land transport. Using helicopters and cars to transport the needed products is expensive and generate relatively high air and noise pollution compared to the drone delivery. This article considers the problem of air pollution occurring during standard aerial and car transport of medical products, with particular emphasis on solution used in African countries. The article presents the ...
