Previous meeting Safety Critical WG meeting #4

Discussion

  • Proposal: We can produce packages that provide node constructs (patterns) for common patterns used in safety-critical systems such as a 2oo3 architecture.
  • Can we do anything with ISO 13849 for control systems of machinery?
    • It does discuss some software aspects at the system level.
    • The patterns idea could work for this standard as well
  • How can we move forward with the patterns idea?
    • What would our output be?
      • Documents
      • Code
    • Need to collect patterns first
      • Good source: ISO 13849 and IEC 61508
    • Start a Google Doc or something where we can start collecting patterns and describing how to do them in ROS
    • List the resources we have available (useful parts of standards, etc.)
  • Proposal: Produce a library to provide useful functionality for increasing reliability or availability, such as Virtual Synchrony.
  • An interesting alternative angle: How do you integrate ROS (as a non-safety-critical part of a system) with a safety-critical part and provide guarantees of non-interference, etc.?

Action items

  • Start a Google Doc for documenting patterns and available resources
  • Take a poll on the regular meeting time
