Unmanned Aerial Vehicles (UAVS) are aircrafts without human pilots onboard. They are attracting increasing attention in recent years because of their important contribution and cost effective application in many tasks. How to find a safe and collision-free path in the environment with obstacles is always an important issue in Unmanned Aerial Vehicles (UAVS). In order to solve the problem of path planning for UAV in dynamic environment, this paper proposes a path planning method with an improved artificial potential field to overcome the local minimum problem. According to detects of the artificial potential field, this paper improves the APF through changing the repulsive potential function. The performance of simulation shows that the improved APF method can help the UAV avoid collisions with obstacles effectively and find the optimal path relatively from the start to the goal by choosing a proper m. © 2016 IEEE.

The principle of polarization angle measurement by means of a polarization sensor based on polarizing beam splitter in place of polarizer was demonstrated. The system model of the sensor was built and methodologies for precise calibration were developed. The static testing under laboratory conditions was carried out and the angle algorithm was validated. The experimental results showed that this novel biomimetic sensor with advantages of simple structure, light weight and low cost could achieve a high degree of accuracy, and it may play a role in the field of navigation.
