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.

Note that it's always a good idea to check this page before the meeting in case inclement weather or something unexpected forces a cancellation or a change of venue. See the monthly announcements below for special cases. Since we share the regular meeting facility with FIRST Washington, we sometimes may need to meet at an alternate location (we hope nearby) in the event of a conflict. We also may have joint activities if the facility can handle the number of people, otherwise details will be posted in the monthly announcements 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 (e.g. this one) for you and notify you of changes. This service will check a selected site up to twice a day for free, more often for a fee.

  • Take a look at the new "Special Events" page just added to capture events of interest to SRS members. It will have links to specific events as well as online calendars. Please let me know if there are items to be added.
  • Check out the first batch of "paper Encoder issues" from the early 90's recently scanned to PDF and added to the Encoder. SRS YouTube video links to various contests and events have been inserted amongst the meeting notes. If you come across any not included, email me the link(s).
  • Take a look at the "Useful Links" page added as a robotics resource.
  • If you haven't come 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 signs will provide details of the alternate meeting location should you miss the advance announcements.
  • Meetings will be followed by an afternoon robot work session (until ~4 p.m., see Upcoming Events below) where we'll help people build and program the Parallax Arduino UNO Robot kit or the Propeller Activitybot kit. 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 contests that are a great way to competitvely pit your robot(s) against others in friendly battles to the death.

Upcoming Events

General Meeting Information

Our regular meetings start at 10am on the third Saturday of each month. They are pretty consistent only rarely being cancelled. If this happens it will be announced here, via our Yahoo Group, and our other social media outlets. See the meetings page for details on the normal location and directions. See the monthly meeting announcements below for special location information if applicable. The "Events" section on the SRS Facebook page has the typical meeting agendas. The planned presentations for upcoming meetings appear below. The Past Presentations page is a presentation archive including their presentation slides (if provided).

Presentations & Events Coming

January 19th
  • The meeting will happen at 21238 68th Ave South, Kent, WA.
  • Lloyd Moore will discuss the challenges of being a self-employed SW/HW developer. Bring your questions and he'll try to provide answers.
  • An SRS Robot workshop will follow the meetng. Workshop Host: Steve Kaehler.
  • This month we are going to have an interactive demonstration of our Workshop robots doing a "follow the leader" figure eight formation. Everyone who has a BOE-Bot of any type, please bring it in. The more the merrier! Set up your robot to follow something in front of it using IR, laser or ultrasound sensor. I will have the lead robot so you won't need to program a figure eight just the following behavior. If you need any help or even need parts we will have all of that for you to get your robot going. I will bring code for the Basic Stamp, Propeller and Arduino, and extra sensors and resistors so anybody can do this. The goal is to make a train of robots doing a big figure eight for the Parallax Figure Eight Challenge which is in the Parallax Forum. Check out the video below to see what this looks like. If you have any questions or suggestions please contact me at

  • Workshop Robot Follow-the-Leader
February 16th
  • The meeting will happen at 21238 68th Ave South, Kent, WA.
