We describe a new low-cost robot design that enables large-scale multirobot research, innovative new curriculum, and multi-robotics outreach to younger students. There are four main parts to the system: the r-one robot, a Python development environment, a camera tracking system for ground-truth localization, and server software to connect all the pieces together. This paper presents our preliminary work on the robot design and our experience using it to teach an introductory engineering class. The hardware can support classes in computer science, electrical engineering, and mechanical engineering. The low-cost and small size will enable more research groups to perform multi-robot experiments on physical hardware. The Python development environment greatly simplifies programming and will make robotics more accessible to a larger group of educators, students, and researchers.
