This thesis regards the design and development of the communication side of a fleet of autonomous service robots operating in the University Citadel of the California State University, Los Angeles. This work is part of the project run by Innotech-System, a start-up based in San Diego, that aims to create an autonomous delivery robot service for students. After a short introduction on robotics and service robots, the first chapter consists in an overview of the project in all his parts, SLAM, Path Planning, Robot Architecture, and a presentation of already existing example of delivery service robots on the market. The focus is then shifted on all the crucial communication aspects of the network of robots.
