Abstract

Collective Robotic Search (CRS) is useful in applications such as radioactive source detection where little to no human intervention is desired. In CRS, a group of intelligent mobile robots collectively explores a dangerous environment in order to locate and converge on a specified target. This project applies two search algorithms, Particle Swarm Optimization (PSO) and greedy search, to a CRS problem containing an environment with multiple targets and obstacles where the entire swarm of robots is needed to complete the desired task. The simulation results for both methods are compared on the following: simulated run time, number of evaluations, distance traveled by the robots, resilience against communication and robot loss, and target convergence percentage. Simulation results show that PSO performs better than greedy search in terms of convergence time, distance traveled, and adaptability, for CRS problems requiring the entire swarm of robots for collective mission completion.

Comparison of Particle Swarm Optimization and Greedy Search for Collective Robotic Search in a Complex Environment

Havener Center, Ozark Room

Collective Robotic Search (CRS) is useful in applications such as radioactive source detection where little to no human intervention is desired.

The simulation results for both methods are compared on the following: simulated run time, number of evaluations, distance traveled by the robots, resilience against communication and robot loss, and target convergence percentage.
