Interest in mobile autonomous robots has been growing recently due to their capacity to cooperate for diverse purposes such as rescue, demining, and security. However, such cooperation requires the exchange of state data that is time sensitive and achieving timeliness with RF communication is intrinsically difficult due to the openness of the medium. This presentation describes a communication layer that improves the timeliness of periodic data exchanges among a team, ultimately reducing the chances of lost packets caused by collisions between team members. The presented work has been running for more than 5 years on the CAMBADA (Cooperative Autonomous Mobile RoBots with Advanced Distributed Architecture) RoboCup Middle Size League Team from University of Aveiro.
