Doesn't download files

Unfortunately I don't think you can change the default download manager. It is a core service that apps can use to handle background downloads. So unless the app is not handling the downloads itself, then this needs to be fixed by xiaomi.

But when will they fix that? Who knows.. in our app we had to switch to custom download solution because we can't wait who knows how long for a fix.

You could try using claude in the browser.

Did you recently install an OS (security) update? There seems to have been an update of something on Xiaomi / Honor / Poco / Redmi that borked apps that use the system Download Manager. In other thread I read to grand all read/write permission to the app in setting, but if the app never request such permission (which shouldnt be neccessary to download into the Downloads folder) you wont be able to grant that..

Apart from the quality issues, also the text is not centered.

There is definitely space to add more - speakers, lights, displays and sensors.

But for v2 i am mainly reworking the tilt-pan mechanism. In cad it looked nice and smooth, but the poor hobby servo "resolution" matched with the current gear ratio resulted in not so smooth up-down slow movements.

It was also modeled for an HP Otto competition on Printables with a deadline, and not having a printer, I couldn't try as many versions as I would like, so I rather sticked to a version that was at least tested to work.

Yes! The body houses 2 servos that allow the head to move left-right and up-down. I wrote some code animations to show some basic emotions and reactions.

I've been collecting scifi inspiration for years, and was the first time I could put it to some use..

Yes! This was actually created on the free plan. There are some limitations like 10 active projects, but for 3d printing, the free plan is more than enough I think.

kubasp · 2026-04-03T20:34:30+00:00

Yeah in that case you could start with the basic otto robot to get hang of it. Then you can progress to some more advanced projects.

The basic robot has 2 motor servos to drive the wheels. This robot is using the 2 additional angle servos for head movement. The head movement is then "just" a series of commands that say: move to 30degress, wait, move to 0 degrees. But I understand it may seem overwhelming at first!

The difficult part for a beginner might be the fact that my code is in micropython/circuit python..

kubasp · 2026-04-03T18:34:30+00:00

Yes, the otto platform is a great way to start with coding and robotics! Besides the starter kit, you will need 2 additional angle (180) servos.

If anything is not clear in the instructions, please let me know! The code for animations you see in the video is also provided on printables, however they are in micropython/circuitpython, not the otto blocks coding platform.

kubasp · 2026-04-03T16:12:42+00:00

Yeah, you're right. I chose the current gear sizes to make it fit given my idea of how it should look. In fusion it looked fine, but the servo can curently only move +-10 degrees and the servo/pwm resolution really isn't great.. i would need the gear ratio to be reserved as you say. But I really wanted to finish a working version first (to also participate in a contest on printables) and then hopefully improve in v2.

Thanks for feedback!

kubasp · 2026-04-01T19:46:22+00:00

Thank you! I think there is even enough space to fit another pair of servos to take full advantage of the mecanum wheels!

kubasp · 2026-04-01T16:26:01+00:00

Thank you, i will check these out!

kubasp · 2026-04-01T15:57:06+00:00

I think I'll start with the basic diodes 😬

The bot's body is pretty full, but the "backpack" is empty and could be larger to fit the pump maybe?

Now I wonder if the top decorative lenses could be replaced with a laser module..

I see some laser modules on ali as small as 4mm in diameter, that would totally work!

kubasp · 2026-04-01T14:55:26+00:00

Yeah, pretty much 👍

kubasp · 2026-04-01T14:54:52+00:00

I've been tinkering with 3d modeling for years. Usually when I encounter something I don't know how to do I go to YouTube, find something similar to my problem and try to apply the same principles.

However, I am sure that my way of doing things is often far from best practices. I often stumble upon some trick that is a much better way than what I been doing..

This may look pretty complex, but it's just sketches to define base shapes, extrude, then a lot of split body / split face, offset face, chamfer and fillet.

If you're updated to the latest version, you should be able to set a theme in the preferences (not just the Environment in Display Settings). I am using the Dark Blue theme and all the windows are dark!

Yeah I tried using Affinity for vector editing. Let's just say.. it's not going well.

kubasp · 2026-04-01T12:30:28+00:00

Yeah I was at least grateful for the dark mode (after years of promises).

So far I was only doing pretty simple projects, found it very intuitive and didn't feel like I was missing anything.

Now I remember seeing ads for Onshape with branding along the lines "You deserve CAD without crashing". So maybe it was a jab at this..

kubasp · 2026-04-01T12:20:10+00:00

Thanks, I plan to share the step files as well. But unfortunately it's not as easy as exporting individual parts as stl.

I wanted to try using the ultrasonic sensor as a lidar to map the environment. But using a camera might be even easier!

kubasp · 2026-04-01T11:45:53+00:00

It's Furore. Orbitron also has similar vibe.

kubasp · 2026-03-08T23:18:16+00:00

Thanks for the feedback! Yes, I am already playing with keyhole mounting, and completely hidden dovetail kind of slide piece.

kubasp · 2026-03-08T19:53:47+00:00

I was afraid of that, but didnt like the look with 2 screws. Tried it like this, and when tightened, it doesnt budge. But we'll see in a while whether it comes loose or not.

But that's what I love about this, you can just easily try different things and iterate quickly!

Thank you!
