The Challenge Of Coordinating Multiple Robots On The Moon

Frameworks are a critical, if underappreciated, component of any space exploration mission. They can range from the overall mission architecture, capturing scientific and technical goals, to the structure of messages sent between two internal components of the system. One of the most interesting frameworks that is getting much attention in the space exploration community is the interaction of multiple robots for a single purpose, known as a multiple-robot system, or MRS. On top of that, one of the most common frameworks for robots on Earth or in space is the open-source Robot Operating System (ROS), which is commonly used to run everything from vacuum cleaners to giant mining trucks. Its most recent iteration, ROS2, even uses yet another framework, known as a middleware, to handle aspects of robot communication such as networking and packetizing data. However, there are plenty of different middlewares to choose from for ROS2, so a team of researchers from the University of Luxembourg decided to try to pick one that would be best for planetary exploration applications.
