Welcome to the Seattle Robotics Society!

The Seattle Robotics Society was formed in 1982 to serve those interested in learning about and building robots. We are a non-profit corporation comprised of a diverse group of professionals and amateurs, high school students and college professors, engineers and tinkerers. Our passion is the creation of cybernetic creatures that challenge the old definitions of life, intelligence, and practicality.

See the SRS Programs page for information on the activities that the SRS does to help promote robotics. There is also information there on getting started in robotics.

Announcements

  • Due to remodeling on Renton Tech's campus, our meeting location has changed. We now meet in room J-305.
  • Meetings will be followed by an afternoon robot work session (until 5 p.m.) where we'll build and program the Parallax BOE-Bot Arduino Robots. Bring your kit (available for $125), a project to work on, questions to ask, or just hang out and see what others are working on.

Upcoming Events

Meetings

Our regular meetings are at 10 a.m. on the third Saturday of each month at Renton Technical College. See the meetings page for details on location and directions.

Note that it's always a good idea to check this page before the meeting in case inclement weather or a holiday forces a cancellation.

If you would like to present at a meeting, or know someone who would, please email Steve Kaehler.

Below are the planned presentations for upcoming meetings. The Presentations page contains an archive of presenters and their topics.

  • September 17, 2016
    • Analyzing Loudspeaker Cabinet Vibrations - Loudspeaker cabinet vibrations are known to adversely affect sound quality. DIY audiophiles who build their own cabinets or modify commercial products use a variety of techniques to reduce these vibrations. Unfortunately, many of the recommended building techniques and commercial products lack specific data documenting efficacy. In the last year, Thurman Gillespie has been working on a low cost system using a digital accelerometer and an Arduino UNO that an audio enthusiast could use to accurately measure the effectiveness of cabinet vibration reduction techniques. He will discuss what he's learned, with a focus on possible applications for robotic systems.
    • The meeting will be followed by an afternoon robot work session (until 5 p.m.) where we'll build and program the Parallax BOE-Bot Arduino Robots. Bring your kit (available for $125), a project to work on, questions to ask, or just hang out and see what others are working on.

    • Engineering for Violin Bow Motion Capture and Presentation - Dick Curtiss will present on his project for capturing bow motion information. Beware, a simple idea can lead down many paths. This presentation will revisit some of those paths, especially those relevant to robotics (e.g. timeout to study DSP - digital signal processing). A comment about bowing from a fiddle teacher more than a decade ago planted the seed for this project: "I can tell you what to do, but can't tell you how it feels." That led to the goal of recording and presenting bow motion information in a way useful for training fiddle students. Much later, a little experience with an accelerometer suggested that device might be the simplest way to capture bow motion information. From that, DSP can be used to get velocity from acceleration. However, there are problems to deal with, such as gravity and other imperfections in the data. That is where the fun begins.

Monday Night Chat

The Seattle Robotics Society hosts a "Monday Night Chat" each week. Official time is 7 - 9 p.m. Pacific Time, but people are often around outside this timeframe as well. Details are on the Contact Us page.
