About this Research Topic
Moreover, for many circumstances in which the environment is complex and the Global Navigation Satellite System (GNSS) is denied, single robots may be insufficient to fulfill specified tasks. They will need to be controlled in connection with their neighboring team members and utilize neighboring information to localize themselves and generate an overall map. The research outcomes can directly benefit many application scenarios prohibited to human operators; specific scenarios include a facility inspection after a nuclear incident, such as Fukushima Daiichi in 2011, autonomous mining, and seafloor profile plotting.
When a group of networked robots is maneuvering in an unknown space, the proposed control strategy should guarantee that the robots are motivated to explore unvisited areas while avoiding losing connections with other member(s). During the exploration, the robots use various sensors to perceive the environment, localize themselves, and fuse their perceptions through information sharing to build a global map. To this end, many open research questions regarding networked control can be raised. For instance, a collaborative coverage control strategy can be devised to enable robots to explore the space while maintaining their connectivity. Each robot is responsible for watching and sending its local surrounding areas.
Realistic constraints such as limited communication and sensing ranges can be considered when designing the control scheme. Specific control-lite strategies based on learning methods, such as reinforcement learning and deep learning, can be employed to motivate robots to more actively and effectively explore the unvisited areas. Communications among connected robots may also tackle the localization problem. With the input of robot perceptions, the designed control schemes lead to the full exploration of the entire unknown space. This Research Topic aims to present the recent research advances in these areas.
