A Survey of Robot Swarms’ Relative Localization Method

Abstract: For robot swarm applications, accurate positioning is one of the most important requirements for avoiding collisions and keeping formations and cooperation between individuals. However, in some worst cases, the GNSS (Global Navigation Satellite System) signals are weak due to the crowd being in a swarm or blocked by a forest, mountains, and high buildings in the environment. Thus, relative localization is an indispensable way to provide position information for the swarm. In this paper, we review the status an… Show more

“…GPS signals can be disrupted or lost due to various factors such as signal jamming, multipath interference, and natural obstructions such as mountains, trees, and buildings. In such scenarios, swarms that heavily depend on GPS can face serious performance issues and may also suffer from complete failure [24]. To address this challenge, swarms must be designed to be more robust and resilient to GPS unavailability.…”

“…In the paper different device-based, monitor-based, and proximity detection methods are compared based on localization techniques, such as angle of arrival (AoA), time of flight (ToF), return time of flight (RTOF), and received signal strength (RSS), and on technologies, such as Wi-Fi, RFID, UWB, and Bluetooth. A similar compilation is presented in [7], where the stateof-the-art relative localization methods for robot swarms are surveyed.…”

“…These methods can be divided into three categories: inertial/dead reckoning, acoustic transponders and modems, and geophysical. Most recently, in [ 16 ], a robot swarm relative localization method was studied, and in [ 17 ], a review of localization, navigation, and communication of UUVs for collaborative missions is presented. In [ 18 ], the fusion of an inertial sensor and a vision is introduced.…”
