- Abstract: This paper presents a distributed scalable multi-robot planning algorithm for
non-uniform sampling of quasi-static spatial fields. We address the problem of
efficient data collection using multiple autonomous vehicles. In this paper, we
are interested in analyzing the effect of communication between multiple
robots, acting independently, on the overall sampling performance of the team.
Our focus is on distributed sampling problem where the robots are operating
independent of their teammates, but have the ability to communicate their
states to other neighbors with a constraint on the communication range. We
design and apply an informed non-myopic path planning technique on multiple
robotic platforms to efficiently collect measurements from a spatial field. Our
proposed approach is highly adaptive to challenging environments, growing team
size, and runs in real-time, which are the key features for any real-world
scenario. The results show that our distributed sampling approach is able to
achieve efficient sampling with minimal communication between the robots. We
evaluate our approach in simulation over multiple distributions commonly
occurring in nature and on the real-world data collected during a field trial.

Currently, humans drive robots to meet scientific objectives, but depending on the robot's location, the exchange of information and driving commands may cause undue delays in mission fulfillment.
An autonomous robot encoded with a scientific objective and an exploration strategy incurs no communication delays and can fulfill missions more quickly.
Active learning algorithms offer this capability of intelligent exploration, but the underlying model structure varies the performance of the active learning algorithm in accurately forming an understanding of the environment.
