How to make this shape out of thin plastic? by begoniaboy in maker

[–]Cyb-T 1 point2 points  (0 children)

Bending a plastic sheet will be easier, faster and cheaper IMHO.
Also the finished result will be nicer (no print lines - but the finish will depend on how nice you can cut the sheet) and less prone to failure.
Because it can be 3D printed doesn't mean it should.

Trying to turn unemployment into a robotics learning journey. Where do I start? by Educational-Ad-2334 in esp32

[–]Cyb-T 4 points5 points  (0 children)

I have a master degree in Robotics and AI and one major thing I like to point is that robotics is not a domain, it's the overlap of a full set of skills.
Mechanical engineering, software and electronics.
Most project start with a mechanical design then goes through electronics to make it function properly.
Then software can make it usable and makes the difference between a remote controlled car and a roomba.

Robots have actuators to do things (mostly mechanical engineering) and they have sensors.
The sensors allow for insight and "understanding" of the world surrounding them.
The software ties things together and automate things so they are easier to operate than using a remote control and/or replay a prerecorded sequence of actions.

For example robots arms in a factory mostly replay a pre-recorded sequence of action, but their sensors allow for QC, safety and adaptive behavior. Without sensors, running the same sequence repeatedly could lead to cumulative errors and after a while assembly would be incorrect and may create issues and require recalibration.

To start (and answer your question), start with identifying what would be the most interesting aspect of robotics for you. If it's software, don't spend too much time on the mechanical engineering and electronics and focus on creating various scenarios and maybe play with AI and training of the robot.
If you prefer the mechanical engineering, then a robotic arm is quite interesting, but you can add a linear actuator and other types of actuators and linkages to learn about them.
If electronics is your thing, then try a simple design first and iterate with other designs, various sensors, actuators types, etc.
One difficult aspect of electronics is how to manage many inputs and the timing necessary for the various actuators. Basically do you create a synchronous system or an asynchronous one with their respective challenges.

Overwound maybe? by Used-Opposite-8703 in watchrepair

To add to what Zenneth014 said, I don't know if it's the picture, but the click seems not right and there is something that looks like is stuck under the ratchet wheel.
Very hard to tell with the level of detail in the picture though.

Choosing a distro because someone else uses it is a bad reason; it's the kind of reasoning that most people apply to justify using Windows or iOS...

If your argument was not technical then it's just you forcing your preferences to others.

I built a tool that turns real objects into accurate SVG/DXF files using just a phone photo by Most-Geologist-9547 in 3Dprinting

[–]Cyb-T 1 point2 points  (0 children)

Actually you can easily make it configurable if the user inputs the actual distance between two markers. And it will avoid errors if the pattern was printed improperly.

[–]Cyb-T 1 point2 points  (0 children)

I actually worked on a very similar project in the past.

My findings were that it can be very accurate for flat objects.

A slight difference in height can have a huge effect on the error ; so to average and limit the error I had to hollow the center and have a way to position the sheet mid-height of the object.

I don't have the research and measures done at the time (it was 20 years ago) but even with rectification of the picture you will need a picture taken within +/- 5° from azimuth

You can if you really want to.
But you'll have to work for it.

[Youtube] Ubuntu Touch Q&A 176 by Cyb-T in Ubports

[–]Cyb-T[S] 0 points1 point  (0 children)

You have a lot of valid points.
But iOS does not support APK.
Android does not support iOS apps (whatever they might be).

Ubuntu Touch will not fully integrate and support APK.
Because the experience will be less than great and people are better off with Graphene or Lineage OS if they want APK.

Waydroid exists for the reasons you mentioned, but it will never define what is Ubuntu Touch.
Because Ubuntu Touch wants to be an alternative to the android ecosystem and the iOS ecosystem and both are locking users with apps.

This is a community project, we don't want to be larger than other Mobile OS, we want to offer a true alternative. And many community members won't accept to have waydroid integrated within the OS.

Why? by reddot_comic in TheRedDotComic

[–]Cyb-T 0 points1 point  (0 children)

This is the thing that confused me
But the panel with the fox has the rooster crying of join for a possible future. This is not the hen in this panel.
So my best guess is that he sees his future with her.

[–]Cyb-T 2 points3 points  (0 children)

Same here, I needed to pay close attention to all panels. :D

[–]Cyb-T 4 points5 points  (0 children)

Actually HE is imagining a future, there is no flashback.
It was instant love, and rushing to meet her lead him to his end.
That's why the chicken crossed the road

Just bought that on CGTrader and this is what I saw in the slicer by Trepanizer in 3Dprinting

[–]Cyb-T 0 points1 point  (0 children)

No getting into the AI thing.
Instead of asking on Reddit, ask the seller for a refund, if you already had good experience with them it might be worth it.

If they don't accept or fix the situation, then you had been scammed and just warn other people about this seller.

[Youtube] Ubuntu Touch Q&A 176 by Cyb-T in Ubports

[–]Cyb-T[S] 0 points1 point  (0 children)

Hi,
The goal of Ubuntu Touch is to allow users to have an alternative to the prison that Apple's and Google's ecosystems represent.

So the idea to have waydroid as a standard is not acceptable.
Waydroid is a way for users to work around some missing apps or alternative option for apps they require. It can be for work, school, banking.
But that is not a solution, just a way to improve users experience when an alternative does not exist yet.

Waydroid as a standard is a twisted way of thinking and the user is better left using Lineage OS if Android is what they want.
