In this paper I present state-of-art development in vision based autonomous landing of UAVs (Unmanned Aerial Vehicles). I present brief overview of algorithms used to solve this particular problem using vision based control which is very challenging and recent topic of research in the field of computer vision and robotics. After that I compare them based on the achieved results recently by diff...

Unmanned systems are physical devices or systems equipped with necessary data processing units, sensors, automatic control, and communications systems that can perform desired tasks in unstructured environments without continuous human guidance. A fully autonomous unmanned system has the ability to gain information about and navigate through an environment, to work for an extended period withou...

Software for autonomous systems is hard to test, given their complex reactions as well as safety-critical behavior. Here simulation-based testing of the control software using a simulation of the environment and the platform of the system supports verification without threat to system and environment. A model-based construction of the simulated environment enables an effective verification by s...

This paper describes architecture for an autonomous land vehicle for high-speed driving without human intervention. This is a model proposed for the DARPA Grand Challenge in 2004, which was to make a robotic vehicle that will drive a desert terrain of 132 miles autonomously. In comparison to other challenges in the robotics domain, this challenge was really different because it encompassed maki...

This paper focuses on a critical component of the situational awareness (SA), the control of autonomous vertical flight for vectored thrust aerial vehicle (VTAV). With the SA strategy, we proposed a linear-quadratic-Gaussian (LQG) flight control procedure for an unmanned helicopter model with vectored thrust configuration. This LQG control for chosen model of VTAV has been verified by simulatio...

The realization of cooperative Multiple Unmanned Marine Vehicles (MUMVs) is a real challenge, due to the conditions of the marine environment. In this paper we show the necessary steps of developments to enable already existing, single autonomous vehicles to participate in a team mission. We describe the design of the control software and put an emphasis on the task of Online Replanning of the ...

Since late 90’s of the last century, rapid advances in technology, mechanical engineering, miniaturization, telecommunications and informatics enabled development and routine deployment of sophisticated robots in many real world domains. Besides many applications in assembly industry, e.g., in car, or electronics assembly lines, defense organizations, together with space exploration and mining ...

As a result of unmanned aerial vehicles being widely used in different areas, studies about increasing the autonomous capabilities of unmanned aerial vehicles are gaining momentum. Today, unmanned aerial vehicle platforms are especially used in reconnaissance, surveillance and communications areas. In this study, in order to achieve continuous long-range communication relay infrastructure, arti...

We present a design of a leaderless formation controller for networked vehicle systems, which uses concepts from sliding mode control and dynamic extension. A single gain varies the importance of the relative and absolute position terms, allowing for tight or loose formations. This approach is proven mesh stable. Applications include formation flying of Unmanned Air Vehicles as well as possible...
