The approach is a viable solution to solve formation problem. The approach allows online planning of the formation paths using a Dijkstra's search algorithm based on the current sensor data. The formation is allowed to be dynamically changed in order to avoid obstacles in the environment. A controller is designed to keep the robots in their planned trajectories. It is shown that the approach is effective and feasible by the simulation of computer.展开更多

Control of the project cost in the project implementation is mainly divided into bidding, contracting, construction and settlement. The following is the analysis and discussions of the author＇s experiences to the control of the project cost in the project implementation and the management measures.展开更多
