In this paper, efficient trajectory planning algorithms and centralized control schemes based on onboard sensors and embedded controllers are presented for outdoor autonomous formation flight. Specifically, the optimal reciprocal collision avoidance (ORCA) algorithm is studied to avoid collision among unmanned aerial vehicles (UAVs) during formation switching. Field experiments have been conducted...
The problems existing in the product design process were analyzed. Applying artificial intelligence theory and technology to the product design field is discussed and one frame of a product design expert system is proposed. According to procedure of product design, the expert system for product design consists of three modules: the information and the data compilation, the assistance innovation design,...
