Lakeside Labs and NES institute of the Alpen-Adria-Universität are working on autonomous multi-robot systems. The research focuses on the organization and communication during an exploration of indoor environments. Such autonomous systems may keep humans from entering hazardous environments by exploring it first. The implementation of wireless communication between robots without having to rely on pre-installed communication hardware, such as wireless routers or cellular networks is one of the tasks. The newly created communication modules are used to exchange local maps produced by robots and to merge these local maps to a common global map. The video shows how our approach works.
