ESP-Wroom-32 Web Server meets some Nema17 stepper's

Gareth's picture

This is a walkthrough on how to control Nema17 Stepper motors using an ESP32 Webserver.

In the example above I am using the local ESP32 webserver to control InMoov's neck screw via a Nema17 stepper motor and 3D printed Gearbox.

Controlling Stepper motors via a Wifi enabled webserver opens up an easy way to control remote devices. The information here shows how this can be done easily and at low cost.

Add win32com Library

Bretzel_59's picture

Hello,

 

I'm trying to use the windows TTS in MRL but I don't know if it is possible to add the win32com library.

I've downloaded this file : http://www.java2s.com/Code/Jar/c/Downloadcommwin32all201jar.htm and put in libraries\jar folder but it didn't work.

under python 2.7 with pywin32, it's quite easy to use windows TTS :

 

import win32com.client


leap motion

Hello!!

 

ive been a bit out of picture but now im back!!! 

Im at the moment trying to use leap motion to control the myrobotlab! does anyone have a clue on how to do it? i know have been done in the past!

 

Even if it doesnt work anymore with the changes on MRL what is the best way to implement information from an outside source (leap) into maybe the python interface? Could someone throw me a hint <) thanks alot

Hi,
Are we ready to package the latest InMoov script from here  https://github.com/MyRobotLab/inmoov 
as part of the build process so they will continue to grow in sync ?

Aduino strange errors

Hi 

I sometimes ( not always ) get some strange errors in the Arduino service.

I think it is some type of timing issue.

Using this little script sometimes reproduce the error.

Hi all ! I want to use this audio amplifier to control volume dynamicaly.
Is mrl can already handle it or this hardware need to be borged ?

Good evening Dave.
Long time ago I have installed this sensor but never used it in interraction with other services.
Don't know if the method I used is a good method but worky great !

this is the code about pir and timer


viewing your virtual inMoov in 3d implemented in inMoov service

calamity's picture

I add the possibility to view a virtual 3d InMoov from the inMoov service.

To view it, you have to add in your inMoov script

i01.startVinMoov()

and

i01.stopVinMoov()

to stop viewing it.

The 3d model should mimic what your real inMoov is doing.
The model probably still needs some adjustment but is looking good.
The fingers and eyes are not working yet


I Love Serializing

GroG's picture

Not that kind of Cereal.  
Serializing is when you squish information into a tiny stream of 1s and 0s.  The great thing about it, is it allows you to send this information over little pipes and wires !   You can move information around. You can make things change remotely. What are we waiting for ?
