These small robots were designed to be a much smaller replacement for robots that are typically used to teach the ROS (Robotic Operating System).
These small robots were designed to be a much smaller replacement for robots that are typically used to teach the ROS (Robotic Operating System). This compact form factor allows educators to develop multi-robot systems that can fit on a desktop, removing the burden of having to arrange a classroom specifically for teaching robotics concepts. A detailed set of logs regarding the development of these robots can be found here and some further details here.
