Tato práce se zabývá problematikou řízení a návrhem regulátoru BLDC motoru. Nejprve je uveden teoretický rozbor zahrnující konstrukci a parametry BLDC motorů a možné metody jejich řízení. Dále je provedeno měření charakteristik BLDC motorů určených pro RC modely. Hlavní náplní práce je pak návrh nového regulátoru ELCERAM pro profesionální RC modely...

In view of a constant growth in the human population on Earth, the provision of a necessary amount of high-quality food looks challenging. As over 10% of the crop yields are annually lost due to the presence of phytopathogens, the development of novel, eco-friendly methods of pest eradication might contribute to avoiding nutritional shortages. Here...

Biological invasions are partly defined by their ability to spread rapidly within invaded regions, posing threats to biodiversity and local species assemblages. The painted bug, Bagrada hilaris (Hemiptera, Pentatomidae) (Burmeister, 1835), originally described as being from India, is an important pest worldwide, mainly due to the serious economic l...

The thermal environment is crucial for livestock production. Accurately detecting thermal environmental conditions enables the implementation of appropriate methods to control the thermal environment in livestock buildings. This study reviewed a comprehensive survey of detection and control methods for thermal environments in livestock buildings. T...

Invasive rodent species represent a principal threat to global biodiversity and ecosystem integrity, particularly on islands. The development of aerial dispersal of rodenticide bait from helicopters in the 1990s was a major innovation credited with driving an increase in the scale, scope, and pace of successful eradication attempts. Helicopter-base...

Traps are one of the most commonly used products for controlling wild pig populations, but every trapping product and process produces different results. Early sexual maturity, extraordinary reproduction rate, and high piglet survivability gives feral pigs the capacity to recover quickly from inferior control efforts which do not target all age cla...

The sparse atmosphere on the surface of Mars provides the necessary flight conditions for Mars unmanned aerial vehicles (UAVs) to perform low-altitude flights. This work presents a comprehensive overview of key technologies in the development of Mars UAVs, with a specific focus on rotary-wing Mars UAVs. It summarizes prototypes of rotary-wing Mars ...
