00:22:53 Mitch: maybe more workplaces use it in the morning
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 n 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
00:50:49 Greg S: https://www.youtube.com/user/gr8gregshu
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 (eg 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? your 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 Nickolas, but I did see the serial connection in the context of a USB adapter to a PC. It makes sense I could have an Arduino or whatever based robot and then send it serial commands from the badge.

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 autocorrect 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 the 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 effect my pacemaker?
01:47:15 Steven Kaehler: https://grpc.io/
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 is the gel that doctors use to smoothly move an ultrasound sensor on your skin.
02:23:00 Nicholas Nadeau: https://www.precisionballs.com/Magnetically_Preloaded_Kinematic_Couplings.php
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: https://github.com/engnadeau/pybotics
02:27:12 James Newton: Amazing talk!
