Cooperative Sensor-based Selective Graph Exploration Strategy for a Team of Quadrotors

This paper proposes an exploration strategy in unknown environments for a team of quadrotor Unmanned Aerial Vehicles (UAVs). Based on the frontier information, the proposed strategy builds a roadmap of the explored area in form of a Sensor-based Selective Graph (SSG) using simple data trees of the frontier and the hub node only. In particular, the frontier data tree is utilized to consider the adjacent frontier sectors as one frontier sector, …
