Fault Tolerance

[patchworquill]

Also known as “graceful degradation”, the control system needs to ensure that when components fail, the system is fail-SAFE (rather than fail-dangerous).

This fault-tolerance strategy and subsequent control system code should take the following approach:

1. Organize the system into named sub modules.
2. Identify submodule dependencies / contingencies.
3. Map out submodule failure and safety strategy in a visual diagram / flow diagram. This also includes the logic that will be turned into code, or circuit elements.
4. Turn visual diagram into code in Arduino.
5. Test and ensure modularity of submodules. Map dependencies.
