Hardware Interfaces Working Group #15 Meeting 11/17 (Thursday)

Thursday 11/17 (HW) Interfaces Working Group Meeting #15

For #15 on 11/17 we will review notes/what has been shared to date from the speaker series on approaches to interfacing with devices.

I will summarize within the WG Minutes, link below, each talk title, speaker and leave room for notes about what was shared relative to approaches around interfaces. Please feel free to add commentary as well to aid in the discussion for 11/17.

Getting together today. Thanks!

Great discussion today.

Some Key points:

  • Most work to date, particularly around manipulators have not focused on semantics that handle motion behavior.
  • Many manuals give clues relative to motion behavior and could provide semantic definitions to support interface development providing for a more consistent driver/interface experience
  • An example is included in the notes of indications of how behavior is handled.
  • While true deterministic motion performance/execution is desired, at minimum we want to represent how motion is derived at a macro level to have developers of a specific implementation to have a sense heading in how things are going to behave.

Thanks again and looking forward to our next get together. Tentatively the next meeting will be December 8! The goal would be to have a couple other robot motion description examples to compare to the one provided in the notes.

Stay tuned!



Sorry if I’m missing something obvious here, but I’ve not been able to find a consistent link to this meeting. The “ROS Event” calendar seems to be inaccurate. I’ve had issues with the .ics linked above as well in the past.

Now it seems like the ics indicates the next meeting is Nov 24 and then Dec 8, is that more or less accurate?


@nnarain thanks for the note, and yes schedule has gotten a bit off, and typically the ICS should be the most accurate. That said, as noted above in my last post Dec 8 is the next occurrence. I will attempt to send a cancellation notice for the 24th since it is a national holiday in the US (Thanksgiving).

I try to get info posted here, and I send out the latest occurrence reminders via the google group as well, and include Twitter to try and cover as many of the communication “bases” as possible. We do not have control over the ROS Event, and rely on someone within OR to make corrections when possible.

Thanks for posting and hopefully at minimum you are able to access the google notes. I also hope to get the GitHub WG working repo in the right place before end of year, with all the supporting work group content.

Thanks again.
