Welcome to the Seattle Robotics Society!

The Seattle Robotics Society was formed in 1982 to serve those interested in building robots and associated technologies. We are a non-profit corporation consisting of a diverse group of technologists and tinkerers. Our collective passion is learning about robots through education and freely sharing our skills and knowledge with our community through meetings, workshops, contests, outreach events, online, and mentoring.

See the SRS Programs page for information on the activities that the SRS does to help promote robotics.

Please see the following recommendations from the King County government. Coronavirus Disease 2019 (COVID-19) Public Health recommendations to protect our community See each meeting announcement below for specific schedule information.

It's always a good idea to check this page before meetings in case inclement weather or something unexpected forces a cancellation or a change of venue. Check here within 24 hours of the meeting (Friday morning) to catch any last minute changes. A nasty forecast would probably cancel the meeting, however if it looks okay through the weekend, things will happen as planned but nasty weather near the meeting time could postpone this month's presenter, so thank you for being flexible.

The monthly announcements detail special cases. Since we share the regular meeting facility with FIRST Washington, we sometimes (rarely) might have to meet at an alternate location (we hope nearby) in the event of a conflict. I will do all I can to avoid this. There might be FIRST activities at the facility if it can handle the number of people, otherwise details will be posted below as soon as possible and on our Facebook page with location and directions to the alternate meeting venue.

If you want an automated utility to ping you when there's a change here, consider VisualPing, a free website that will monitor websites and notify you of changes. This service will check selected sites up to twice a day for free, more often for a fee.

  • Check the "Special Events" page for new items of interest to SRS members. It will have links to specific events as well as online calendars. Please let me know (below) if there are items to be added.
  • Check out the "paper Encoder issues" from the early 90's scanned to PDF and added to the Encoder. SRS YouTube video links to various contests and events are inserted amongst the meeting notes. If you come across any not included, email (below) me the link(s).
  • Check out the "Useful Links" page of robotics resources. If you come across something not included, email (below) me the link(s).
  • If you haven't been to one of our meetings for a while, we now normally meet at the FIRST Washington Fieldhouse at 21238 68th Ave South, Kent, WA (as of January 2017) unless otherwise noted below.
  • Signs at the front door of the building will direct you either upstairs to the conference room or straight through the building to the warehouse, or a sign in the window will provide details of the alternate meeting location should you miss the advance announcements.
  • Meetings are usually followed by an afternoon robot workshop session (until ~4 p.m.) where we'll help people build and program the Parallax Arduino UNO Robot kit or the Propeller Activitybot kit or assist as we can with other projects. Bring yours, a project to work on, questions to ask, or be a resource for others and hang out with us. Sometimes we host one or more Robothon contests providing a great way to competitvely pit your robot(s) against others in friendly battles to the death prior to the public Robothon events.

    Please send any past meeting pictures you'd like to share to the SRS Gmail above. Include helpful subject line text with the message.
