It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.
This paper investigates the formation control system design for multiple quadcopters with path planning for territory surveillance. The development is manifested with nonlinear dynamic modelling, position and attitude control of the quadrotor UAVs followed by leader-follower formation control for multi-drone systems operated with Rapidly-exploring Random Trees (RRT) based path planner. The simulated experimental validation demonstrates practical potential of the proposed framework.
