Systems
This section describes what systems are present on Perseus, what they are and what they do. For information how to develop each of these systems check their corresponding pages in this section.
Fundamentally, the rover is split into two main sub-systems: Hardware, and Software. The software system lays out how the code interacts with itself and its environment, as well as which bits do what. The hardware system goes over how everything's physically connected and laid out, as well as the electrical wiring.
Whilst those two documents contain the majority of the information you'll need day-to-day, there are also some other moving parts to consider as well:
- The CI/CD pipeline is what runs our automated testing and handles deploying this very website
- Speaking of this website, its build process can be a little bit convoluted, so it gets a document too
- If you're writing firmware or a hardware interface that talks on the CAN bus, you'll need to read through what we've titled the Canifesto
- You've probably noticed by now that we use Nix to manage all our software - this gets complicated quickly and there's only so much that source comments can do, so it's explained here
If you're just looking for a high-level overview, this diagram contains the basics of the information flow between modules (as well as some power information):
