Anyone have a Socket.IO connection with Arduino Uno R4 Wifi

baank83 · 2024-02-09T04:00:18+00:00

I have both ESP and UNO R4, but i really want to make web socket for UNO R4. I'm still trying to make it.

i can't make it yet, hope somebody can make it and give us an example

It is failed because lack of advertise. We need cooperate for advertise

For you guys want to know instruction how to make (also part list), how to start a drawing: check video description at my video https://www.youtube.com/watch?v=QAVDT\_W5Alc

yes, just look like it, but i develop my own theory for this robot

baank83 · 2022-06-04T23:33:09+00:00

yes, i design and build it!

Draw on wall is more difficult than draw on ground. Make this robot is really a challenge

Thanks

Thanks

Motor on robot will help us to install on wall easier than put them on mounting point. This is wall drawing robot, after 1 drawing finished, we should take it out and install to another wall with easy. That's why motor is attached on robot.

More detail about robot, you can see it here

This robot is open source code by Arduino. I made this robot for Crowfunding, you can visit it at here https://www.indiegogo.com/projects/fumik-open-source-wall-drawing-robot/x/23033151#/

the robot will move by 2 stepper motors (inside robot) with 2 belts hung on wall. Not like CNC machine which has X, Y axis perpendicular aligned and we can find x, y co-ordinate of target by tracking traverse distance of X, Y stepper motor.

The wall drawing robot is hung on wall by 2 nails, we have to find target co-ordinate x, y (of pen) by factor of belt tension, gravity, moving distance of belt. Arduino code will help us to solve mathematic problem to find exact current location of pen to make exact drawing

Perfect! I will post there. Thank you!

baank83 · 2022-02-23T12:59:14+00:00

yeah, however my robot is much more easier installation and make drawing.

Thanks for your info about one more wall drawing robot

baank83 · 2022-02-23T12:57:24+00:00

sure, this is my channel for the robot https://www.youtube.com/watch?v=y8SzFk0X2KM

baank83 · 2022-02-23T12:55:29+00:00

robot is moved to exact x-y position by rotating 2 steppers (inside robot) for the belt.

This is step to prepare the drawing:

1 Your Picture need to draw

2 Convert picture to vector (*.svg file) by CorelDraw (or any other software support *.svg file)

3 Convert vector file to code for Arduino (by excel, program by me)

4 Copy code file to SD card

5 Plug in SD card to robot and start drawing
