A ground control system (GCS) for unmanned aerial vehicles (UAV) is developed in this paper. Different tasks, which include real time communication between GCS and UAVs, data processing and storing, localization, path planning and so on, can be accomplished in the proposed GCS. To address the issue of path planning problem for UAVs, a new path planning algorithm based on potential function is proposed to drive the UAV to its destination in this paper. Time-varying gain adjusting method is used to enable the UAV obstacle avoidance ability under the constraints for the translation velocity. Lyapunov based analysis is used to prove the stability of the proposed algorithm. Numerical simulation results are included to demonstrate the performance of the proposed path planning design.

Microsoft Kinect cameras are widely used in robotics. The cameras can be mounted either to the robot itself (in case of mobile robotics) or can be placed where they have a good view on robots and/or humans. The use of cameras in the surgical operating room adds additional complexity in placing the cameras and adds the necessity of coping with a highly uncontrolled environment with occlusions and unknown objects. In this paper we present an approach that accurately detects humans using multiple Kinect cameras. Experiments were performed to show that our approach is robust to interference, noise and occlusions. It provides a good detection and identification rate of the user which is crucial for safe human robot cooperation.

We introduce a new development system for swarm algorithms to be used in research and education, composed of a swarm of Wanda miniature robots, a beamer assisted arena for robot experiments and a new framework for the accurate simulation of robotic swarms. TheWanda robot is easy manufacturable and was especially designed to be used as a swarm robot. It is accurately implemented in the new simulation framework which provides powerful methods for the efficient and exact simulation of sensor data for all kinds of vision based sensors, such as rgbsensors, camera sensors, infrared communication and ranging sensors by utilizing graphics hardware. Utilizing the behavior based controller language MDL2Ε which is implemented on the real robot and in the simulation, the complete system aims to allow for a quick and easy development, testing and demonstration of swarm algorithms.
