Deliberative capabilities are essential for intelligent aerial robotic applications in modern life such as package delivery and surveillance. This paper presents a real-time 3D path planning solution for multirotor aerial robots to obtain a feasible, optimal and collision-free path in complex dynamic environments. High-level geometric primitives are employed to compactly represent the situation, which includes self-situation of the robot and situation of the obstacles in the environment. A probabilistic graph is utilized to sample the admissible space without taking into account the existing obstacles. Whenever a planning query is received, the generated probabilistic graph is then explored by an A$^{\star}$ discrete search algorithm with an artificial field map as cost function in order to obtain a raw optimal collision-free path, which is subsequently shortened. Realistic simulations in V-REP simulator have been created to validate the proposed path planning solution, integrating it into a fully autonomous multirotor aerial robotic system. [less ▲]

The goal of the work presented in this paper is to facilitate the cooperation between human opera- tors and aerial robots to perform surface inspec- tion missions. Our approach is based on a model of human collaborative control with a mixed ini- tiative interaction. In the paper, we present our human-robot cooperation model based on the combination of a supervisory mode and an as- sistance mode with a set of interaction patterns. We developed a software system implementing this interaction model and carried out several real flight experiments that proved that this ap- proach can be used in aerial robotics for sur- face inspection missions (e.g., in vision based indoor missions). Compared to a conventional tele-operated inspection system, the solution pre- sented in this paper gives more autonomy to the aerial systems, reducing the cognitive load of the operator during the mission development.
