Swarm robotics is an appealing approach for education and experimentation: students can learn to program robots to perform individual tasks and also explore how groups of them can coordinate to collectively perform better. However, the deployment of a swarm robotics laboratory is often impractical for many institutions due to the cost of acquiring multiple robots and the necessary infrastructure. To address this limitation, we present ATRIZ: a remote and open laboratory for swarm robotics. ATRIZ is an accessible platform with a modular architecture that supports users management, experiment control, real-time video streaming, control scripts execution, and reports generation. Preliminary testing has shown ATRIZ’s reliability, security, and usability. The system is currently operational in a dedicated robotics classroom at Universidad de Nariño, Colombia, and is intended to enabling regional institutions to access to swarm robotics infrastructure without the burden of developing it locally.
