"DaveFer" is 25-year veteran of the software industry, having worked at Microsoft, Dell Computers, and 3M Company directly on such amazing products as MS Outlook, Windows 7, and Dell PowerEdge server (aka Google Search Appliance).
In May 2022, Dave accepted an offer from Lockheed Martin Space to work on embedded systems in the Orion Spacecraft (crew module) which will carry astronauts to the moon and eventually to Mars.
Dave is currently enrolled in the MS Finance and Economics program at West Texas A&M University where his focus is on Econometrics and Machine Learning.
Dave served in the Peace Corps from 2004-2007.
Dave received his BA degree in Economics in 1988 from Stockton State College in NJ (now Stockton State University). At Stockton, Dave was inspired to study Econometrics by his instructor, Prof. Elizabeth Elmore. At NYU in 1990, Dave also had the distinct honor to study with Prof. William Jack Baumol (Google "Baumol's cost disease").

I think I need some filter on the power line. I suspect the motors are creating current surges that are disrupting the video, which is on the same circuit.

Thank you for the tutorial! I am able to run the steps until the last step where we see the print statement in the runloop on ubuntu linux. For some reason, the print statement does not get executed which means the status received is not successful. Was wondering if anyone else has run into that problem?
Thanks, that was helpful! Before sending an event, how do I create a "subscriber ID" on the bus, so that other apps listening can subscribe to this MsgID?
Note: if you are doing this on Fedora or any other RPM-based Linux distro, install the package "prename" and use it the same way as in the video.
Promo'SM 😞
Sorry, could you help me understand your comment?
how do you make it autonomous? lidar or visual
Thanks for your great question! And thanks for watching. There are a variety of proximity sensor techs that we could use for object avoidance: IR, Ultrasonic, Lidar, even radar. I have some inexpensive radar modules I’m considering. But I think we will start out with two front-facing, IR sensors set to detect objects about 50 - 100 cm ahead. But these technologies aren’t mutually exclusive. And there are advantages & disadvantages to each. For example, ultrasonic is known to sometimes irritate pets; IR sensors are prone to problems in bright sunlight; radar would have problems detecting lighter/softer obstacles - many materials are transparent to radar. What are your thoughts? What would you like to see us use?
ok, this look really cool !! Looking forward to next steps
Thanks, man. Yeah, Episode 2 will be demolitions. :) We will be disassembling the target vehicle. Hoping to have it posted before your RC 4x4 arrives. LOL

Nice, thanks. That's great info. 👍
It helped me a lot Please continue to upload it
This is interesting. Have you tried this under NOS3, the end to end simulator out of NASA IV&V team?
No, I haven't. Thanks for mentioning it. I'll look into it. Just published the next tutorial in this sequence.
According to this test shop, they are running cFS under NOS3. th-cam.com/video/3xln4CMf5SM/w-d-xo.html In another NOS3 demo video I saw, the also appeared to be running cFS.
@@fourierautomation51 Yes, I’ve seen that video, which is why I’m bringing up a NOS3 machine right now actually. I’m not interested in cFS so much as at the prospect of being able to close the entire flight and operations loop under simulation. If NOS3 works, it has the potential of being the enabling accelerator for a bunch of stuff.
@@RobertLeeAtYT I started looking into the same thing last night. I'll let you lead that effort; Plz let me know how that goes for you. And please connect with me on LinkedIn.com. Best wishes.
@@fourierautomation51 Well, it works. Came bundled with a full cubesat sim - reaction wheel, radio, the works. If you get crash at vagrant up, look at the error message. It'll say something about audio set up around line 134. Edit that file. Just remove the reference to audio device.
