  From both an educational and research point of view, experiments on hardware
are a key aspect of robotics and control. In the last decade, many open-source
hardware and software frameworks for wheeled robots have been presented, mainly
in the form of unicycles and car-like robots, with the goal of making robotics
accessible to a wider audience and to support control systems development.
Unicycles are usually small and inexpensive, and therefore facilitate
experiments in a larger fleet, but they are not suited for high-speed motion.
Car-like robots are more agile, but they are usually larger and more expensive,
thus requiring more resources in terms of space and money. In order to bridge
this gap, we present Chronos, a new car-like 1/28th scale robot with customized
open-source electronics, and CRS, an open-source software framework for control
and robotics. The CRS software framework includes the implementation of various
state-of-the-art algorithms for control, estimation, and multi-agent
coordination. With this work, we aim to provide easier access to hardware and
reduce the engineering time needed to start new educational and research
projects.
