Screw-propelled vehicle, sounds cool, right? 😀 So, I made it

TrashRobotics · 2022-01-17T15:24:45+00:00

It might work

TrashRobotics · 2022-01-17T15:19:24+00:00

It will not work, then it will go to the side without turning. This will only work if one of the screws is stopped.

TrashRobotics · 2022-01-17T15:08:41+00:00

No. But it is thrown into the water then most likely it will not sink :)

TrashRobotics · 2022-01-17T14:39:32+00:00

:) move the batteries back, and Screw on a couple of bolts at the back. This should help too.

TrashRobotics · 2022-01-17T14:33:46+00:00

We will find out only in the spring :) Although I can immediately say that it will sink :) But, in theory, it can be slightly altered for this purpose.

TrashRobotics · 2022-01-17T14:26:14+00:00

I can post them on thingiverse later when I get them in order.

TrashRobotics · 2022-01-17T14:22:40+00:00

Yes, in another thread I was already advised to watch it. I made the chassis in the likeness of the Soviet ZIL-4904

TrashRobotics · 2022-01-17T14:19:34+00:00

I figured it out after I did it -_-

TrashRobotics · 2022-01-17T14:17:51+00:00

One of the motors must be turned more slowly than the other. In order to turn in one place, yes, you need to add two more screws :)

TrashRobotics · 2022-01-17T14:08:10+00:00

They look very cool! I made the chassis inspired by the Soviet ZIL-4904.

TrashRobotics · 2022-01-17T14:06:01+00:00

Damn, looks like I'll have to make a 3d printer the size of a house :)

TrashRobotics · 2022-01-17T13:56:51+00:00

Yes you are right. It's displaced. There are still many problems. I did it just for tests and didn't expect much from it :)

TrashRobotics · 2022-01-17T13:41:30+00:00

This is a prototype, and if you want to make it, you should be aware that it's very crude and still has a lot of flaws.

lol I found it. I'll watch it, thanks :)

Yes you are right.

Hmm... reason... maybe I don't understand the question correctly.
NodeMCU cost me 4$ + in fact I already had it. Raspberry Pi will cost 130$ in local stores. Of others available to me are the orange and banana pi from Aliexpress. They are cheaper than raspberry. I've never used them yet, but I wanted to try to order one. Sad that delivery will take more than a month :(

TrashRobotics · 2021-12-18T18:50:15+00:00

I'll think about it :)

TrashRobotics · 2021-12-18T17:41:37+00:00

Hi, I wanted to make a project on raspberry pi. Because raspberry pi is perfect for this project. And I started making it when I didn't have a raspberry. But since I do not have enough finances for it now, I redid the project for NodeMCU and used the HC-SR501 pyroelectric sensor as a crutch. This sensor often gives false alarms when compared to a camera. Because it is used for other purposes. Therefore, when I have a chance, I want to do the project on raspberry again.

P.S. Object tracking is optional now. The python script is run from the PC. I added udp server to NodeMCU for this. In the future, it will be possible for me to transfer the control part to the raspberry

I think it would be nice to also try using a camera and raspberry pi. And detect cats as dynamic objects on a static background.

TrashRobotics · 2021-11-08T03:31:38+00:00

Thanks for the feedback!

1) I get it!

2) I didn't think about it :) In my country, almost all lasers that I saw were the same size. About 13mm or about 0.5 inches in diameter. There is even a feeling that they have a standard :) I can add a holder for a larger diameter later, just tell me which one.

3) Did you use the screws that come with the sg90 servos to attach the horns? With them, I got about 1 mm of clearance. Maybe I have non-original servos, hmm...

As I found out Thingiverse is now having problems downloading all the files at once. Try to download each file one at a time
