Robot lawn mower with Arduino and STM32
I really don't have time to make a full format video but I want to show you what I've already done months ago.
It moves imitating snake pattern and checks it's direction using digital compass. The bumper uses tensoresistors to feel obstacles, that is why it is so stiff.
The main board is controlled by STM32f103 and the bumper is controlled by an Arduino pro mini.

My new mouse
zhlédnutí 88Před 3 lety
I switched my wireless mouse to 18650 li-ion cell and 3D printed a custom case for it. In the end I got used to it and edited the entire video with it. 18650 charging module and MP1584EN adjustable step down converter were added.
My Raspberry Pi 4 Case
zhlédnutí 2,5KPřed 3 lety
Raspberry Pi 400 came out but you already have Raspberry Pi 4? there is a solution:) stl files: www.thingiverse.com/thing:4818729 The keyboard I used - www.aliexpress.com/item/32999100875.html?spm=a2g0s.9042311.0.0.264d33edTswzZT&_ga=2.59634733.1816012528.1619637119-1936315054.1577408009&sku_id=66971898086
Ball-track with an elevator
zhlédnutí 7KPřed 3 lety
I soldered a ball-track using a steel wire and put an arduino-clone to control the elevator lifting a steel ball. To make a sand-like surface - epoxy and ceramic dust were used. To drive the elevator I used a NEMA17 stepper and DRV8825 stepper driver. The speed of a mechanism is controlled by the know on the front panel.
Super simple actuator

Twisted string actuator is the simplest actuator with a motor I know of. But there is a catch!
Giant 3D printed servo
zhlédnutí 583Před 3 lety
This servo is so powerful that I couldn't even test it properly. Although according to my calculations the torque is insane! That video about turning a DC motor into an RC servo with Arduino - czcams.com/video/3pYWLF8qw-g/video.html
DIY robot vacuum cleaner
zhlédnutí 19KPřed 4 lety
It's made out of usual components everyone can find on the internet. I used: drv8825, arduino pro micro, cheap distance sensor, the cheapest brushless motor with an ESC(the whole thing with the brushless motor i would replace with a brushed one in this case), 2 nema17 steppers, and 3s BMS for the lithium cells. The connections and the code are here - drive.google.com/drive/folders/13rZzDs3Zq_r-...
3D Printed Robot Vacuum - the first test
zhlédnutí 1,5KPřed 4 lety
I 3D printed a robot vacuum and now i'm testing it. in the video the turbine is unplugged because I haven't received the batteries yet so it takes power out of a flashlight laying on the top.

Very cool
Lovely project. The most complicated and satisfying paperweight :)
What kind of wire did you use?
I want to use only one load cell
Arduino is also do ADC so I just need to amplify my signal coming from load cell output . Earlier I was tried with op amp but it didn’t work . Please help me with the schematic of connection and code for arduino
This value is very useful for me could you please help me with my setup. I am also using load cell with hx711 but now I m facing difficulty becoz its sampling rate is 10 hz so I am only getting 10 to 11 data points per second. Can you help me to made the setup without hx711
Hello Lery
Hello Lery, can you send me the code and the parts you used for this cleaner because the video you recommended for the code to be in was removed
hi. now i would do all of it differently but in case if some elements are helpful i changed the link in the description where i put connections and the code. also there should be capacitors with those stepper drivers (they are not shown on the picture)
@@lery7341 Thank you so much Lery : )
Can you shear the code?! Because the link on the description doesn't open
Would it be possible to modify this so that the value does not immediately drop to zero when the sensor detects a load? I would need some intermediate readings from the sensor so that I can evaluate the load on the surface area. The values don't have to be exact, but only indicative.
i think you just need to play with values of resistors on the output of the opamp. there are lots of videos with opamps and how to get the voltage amplitude you need.
The specific video tutorial is no longer available, can you show me how to make your robot,Thanks
Good job mate!!
The sample rate of the HX711 can be a lot higher than you think. I'm currently getting 133 samples per sec using a crystal on the XO and XI pins. Although I think your solution is good for the application you have. Why use a fancy ADC if you don't need it.
Should have mentioned 18.432MHz is crystal value but datasheet says 1 - 20MHz can be used.

Omg it is sooo good
is usb port with yellow tape for keyboard?
correct. it's soldered directly to the board so i plugged the port to avoid accidental usage
Impressive so far !! I hope my build will be ready this summer !
Wonderfull robot ! Great job !
Great ingenuity !
Thankyou....
Color scheme reminds me of the 8-bit Atari XL cases.
your work is amazing, I'm very interested to be able to make it, can you help me to get all the components and the code. thank you
you are so creative, it seems you can share a lot of knowledge with others. thanks for the creative idea. bravo
Very Good 1
Very well done, what is the total voltage of those batteries? I'm working on something similar, but with LIDAR (still way behind you).
Nice
Wow
good design. looks like the 8 bit computer that never was
Very nice
Slick design! What about other Raspberry models?
it's not the first case. other just aren't worth showing. i might make one for the Zero model but i can't guarantee just now.
Very nice build, congratulations!
There are some really neat ideas here. Thanks for the video.
Hello Lery I would like to have some information. First, what is the resistance value on the distance reading pin? For the limit switches on the front, the contact to use is NO or NC. I try in vain to make my prototype work but I am unable and I do not understand why. Thank you very much. Michel Lpointe In Quebec.
to pull the distance pin to ground i used 10k resistor. but i didn't quite get the second question. it's difficult to repeat someone's project. you never now what could go wrong. the only solution is to isolate each part of it and debug. then slowly add them into your project one by one.

Sir please send circuit and code
Do it yourself
Sir please send circuit and code
the next video covers these moments - czcams.com/video/BFjXswOUm-M/video.html
I have some Questions: how many Wats Is this thing eat? And what bldc motor Is powering the vacuum and why Is the robot so big And why doen't any DiRT filtr the motor Is powerful enough to suck IT od the filter Is in her?
I made another video to cover these moments - czcams.com/video/BFjXswOUm-M/video.html
man pls upload the next video ı want to build one by myself thanks to you <3<3<3
Very impressive!
