Meeting Slides

Presentation Slides and on Nicholas Nadaeu’s Website

Chat Text from Zoom:

Members who shared projects: Bill H., Greg S., James N., John J.. Carol H.

00:22:53 Mitch: Maybe more workplaces use it in the morning (Zoom screen sharing is slow this AM).

00:44:12 James Newton: I’d like to share a bit about Hackaday Supercon (nov 4-6, Pasadena, CA). Amazing event, really recommended, and the “badge” this year is just stunning. A retro computer, with front panel and lots of blink and lights. I’m just in love with it. (and yes, it’s not a robot, sorry… you should give priority to actual robots here.)

00:47:41 Mitch: Maybe it was just a really good walker (re: Bill H’s “Johnny Walker” robot).

00:47:41 Mitch: Maybe it was just a really good walker

00:50:49 Greg S: 

00:51:51 James Newton: Very official!

00:53:26 Nicholas Nadeau: Greg, what will be your approach to door opening?

00:54:37 Don: These are really interesting demos. I joined the group with zero knowledge on robotics, but want to take it up as a hobby. Any pointers on how I should go about building my first robot?

00:55:23 Colin Leuthold: There is a beginner robot kit available.

00:55:57 Nicholas Nadeau: Don, I personally recommend anything from Sparkfun (e.g. Jetson, Arduino, RPi bots) as a hardware starting point. For software, follow ROS tutorials 🙂

00:56:47 Don: Noted. Thank you.

01:03:48 James Newton: “jaws of life” but on the robot and for a fridge. 

01:04:50 Nicholas Nadeau: James, did you listen to the latest Hackaday podcast episode? You can cross TX/RXs between badges and push code from one badge to another. Probably control a robot too.

01:04:52 John Jennings: Steve, I can share a little on my popcan robot if we have time.

01:07:09 James Newton: I haven’t yet Nicholas, but I did see the serial connection in the context of a USB adapter to a PC. It makes sense that I could have an Arduino or whatever-based robot and then send it serial commands from the badge. 

01:11:04 John Jennings:

01:11:24 James Newton: Nice job John!

01:11:44 kevin: Q: Looks like a Lidar sensor on top?  Which one is that?  

01:13:35 James Newton: Nicholas, sorry about the auto-correct there. 

01:15:11 kevin: The one that’s about $300 online? 

01:15:42 James Newton: hee! hee!  You said doo doo.

01:18:16 kevin: Yeah, I’ve seen that one.  There are several RPLidar models, I think! 

01:23:29 Mitch: Does anyone here know of any robotics companies in or around Seattle that are looking to hire? I’m a mechanical engineer looking for an interesting opportunity.

01:36:16 James Newton: What methods are you using to measure the actual positions? MoCap? Pharo Arm? External Joint encoders? Etc…

01:37:42 James Newton: Good lord those are expensive!

01:39:23 carol: I wonder how those magnetics would affect my pacemaker?

01:47:15 Steven Kaehler:

01:50:36 James Newton: Bloomrpc is a GUI for debugging / testing / making grpc messages:

02:01:31 Mitch: Thanks for the interesting robots! I will have to catch the rest of the presentation on Youtube later. Hope to make it back next month.

02:01:33 James Newton: When you say hardware in the loop… did you use FPGA? Or do you mean an embedded system?

02:04:20 Greysen Petersen: What is that gel in the path of the robot on the leg?

02:17:57 carol: That’s the same gel that doctors use to smoothly move an ultrasound sensor on your skin.

02:23:00 Nicholas Nadeau: 

02:23:19 Bob: The gel basically provides a good acoustic interface between the sensor and the human so there are no discontinuities.  At one time we used K-Y jelly.

02:25:49 Lloyd Moore: Great talk!!!!

02:26:07 Nicholas Nadeau: 

02:27:12 James Newton: Amazing talk!
