1/18/20: This month's meeting had a turnout of about 30 people. The meeting was facilitated by Steve Kaehler. We met in the FIRST Fieldhouse warehouse.

The meeting was kicked off with a video showing the time-lapsed assembly of a 777 at the Everett plant. The video shows 17 days of work compressed into 3 minutes. It is an amazing thing to watch the huge components of this jet flying around the factory.

SRS Polo shirts are available at meetings for $30 (card, cash, or check). The 2019 Robothon T-shirt are available for $15.

Club Business

  • We talked about the ongoing need for backup meeting leaders who can run things when Steve isn't available. There are a couple people who have done this but more options are always better. Talk to Steve at a meeting or contact him via SeattleRoboticsSociety(at) if you can help.
  • The usual slides were presented and contact information for potential presenters was solicited.
  • Steve is looking for people interested in sending out emails to invite potential presenters to come talk to us. It currently takes about eights asks to get one accept. This means it could take a hundred speaker requests to fill the calendar for one year. He needs people willing to research potential presenters and then send them a customized template email addressed. He can provide the template and general instructions. Include the SeattleRoboticsSociety(at) address in the cc: line so he can see any responses and address them. It is time-consuming to find and contact so many people and help would be greatly appreciated, especially if we want to have a full schedule of presenters.
  • We talked about the transition of our list server from SeattleRobotics@YahooGroups to The Contact Us pages has the new information for joining and using this new list host. There are MBOX formatted files containing all the messages from the SRS YG located here for your convenient access if you want to look at or download them yourself. They also on the website which should eventually be indexed by Google and available using the website search box in the left sidebar.

Meeting Pictures on Google Photos. If you have other pics you'd like to share please send them to SeattleRoboticsSociety(at) The following people shared something with the group:

  • Dick presented his new experimental platform. It is a 2 wheel differential drive robot with a Teensyduino as the master brain. 2 auxiliary casters provide balance. It uses an Nimh battery with Pololu Motor drivers. Also includes Pololu Wixel boards to enable a remote kill switch. It features a TOF Lidar sensor. Dick’s first priority is studying navigation issues.
  • Doug showed us his M5Stick C. This is a small development board that includes a CPU, accelerometers, a rate gyro, 3 buttons, and a small color LCD screen. It is powerful enough to run the game of life. Doug is reprogramming it using the Arduino IDE to wrap screens so that a panoramic display is created.
  • Will showed us his crawler robot tank. He obtained the platform from Amazon for about $100. It has a 5kg payload and included a battery compartment for 2 each 18650 LiPo batteries. The two batteries he used were rated for 3000 mAhrs. The platform also includes two 9 volt gearmotors with built-in encoders. The CPU he added is an Arduino DUE and he also mounted a dual motor driver from Pololu rated at 2.5 Amps per driver. He eventually will add a Jetson Nano. His ultimate plan for this platform is to carry around his 100 ounce drink mug! See the meeting pictures.

Feature Presentation

    Our presentation was an open forum discussion about the Internet-of-Things (IoT) and the Industrial Internet-of-Things (IIoT) facilitated by Steve Kaehler. Here are the slides.

      IOT is:
      -Cell phones
      -Medical devices
      -Automobiles and roads
      -Energy Management
      Whatever you can think of:
      -The biggest areas of concern is Security.
      IOT ecosystem layers:
      -Data Collection
      -Network connections and security
      The factors affecting adoption of the IOT are:
      -Fragmentation of offerings
      -Legacy support
      -Communication protocols
      -Planning to date has been secondary to engaging with the ecosystem.
      -We are already surrounded by IOT devices.
      Questions abound:
      -Do they make our lives better?
      -Do they make our lives safer?
      -Do they help humanity in positive ways?
      -What are the downsides?
      -A primary question is how much really needs to be connected?
      Do we really need IOT?
      -What might it be like if everything is connected?
      -Will our lives be better?
      -Will it help in significant ways?
      That’s all folks.

The Workshop

    The afternoon workshop was canceled due to lack of participants. We will have these in the future as long as people want to attend.
