Stepper motor service?

Jan Janson's picture

Hi,

I want to experiment with stepper motors as an alternative for some servos in my InMoov robot.
Searching on MyRobotLab.org gives me some messages about this subject and I even see messages about a stepper-service in MyRobotLab that for some reason is no longer supported.

Can somebody tell me why this stepper-service is no longer supported? Is there an alternative? Are there any plans to pick this up again?

Regards,
Jan

Hi GroG

This is the error I get. The Arduino IDE shows the spash screen and then stops with this message:

I have replace the drawing with mesh. I still have to do some adjustment as the movement seem to be a bit offset but progressing

 

 


MRL 1.0.1943 - Servos

pouleto's picture

Hi,

In previous versions (1.0.1723) I had to use setVelocity(0) function to make my servos (HK15298B) working properly (very slow). In version 1.0.1943 setVelocity doesn't work, and without this function my servos are very slow.

Note: Arduino softaware gives a compilation error for MRLComm.ino because of type issue.

MRLComm 38 not MRLComm 55 expected ?? Do I need a specific MRLComm for MRL-1943?

power sensor for servo protection?

seen that some cheap power sensors are available at aliexpress.

Any chance I could use some of these to protect my servos? I think I would need to sum up the last 1 or 2 seconds of measurments to allow for short high phases?

how to upgrade to new versions

harland's picture

I want to try the latest version of MRL (1.0.1938) on Azul. I am currently using ver 1.0.1859. I think I read in an eariler post that you don't have to delete everything in your MRL folder. You can I just delete the myrobotlab.jar and copy in the new version? Then run mrl.bat. Now that we are using programAB, gestures, and different speech, The mrl folder has even more folders. What is the right way to upgrade?

Starting up and using version 1723 and other problems!!

Hi everyone

Help please with setting up myrobotlab

I was using Gaels V4 script with myroblab 1412 and I had most servos working OK, could hear the acapela voice on start up but never manged to get voice control working.  I could not attach the stomach servos however.    I could succesfully manually control most of the my robot.

MQTT Service

javadoc

MQTT is one of the protocols lumped in with the "Internet of Things" (IoT) and it can be used for lots of things. An MQTT client has been borged into MRL.

 

Here's a screenshot from my Android phone running MyMQTT connected to the same broker.

 

UAE professor uses 3D printing to make highly personalized, advanced prosthetic arms

Hi all,

Take a look at http://www.3ders.org/articles/20170201-uae-professor-uses-3d-printing-to-make-highly-personalized-advanced-prosthetic-arms.html

The guy is working on Gael's arm!!! Uh, I think that's called plagiarism.

Please leave a Comment at the bottom of the page and tell them they are showing Gael Langevin's Open Source creation and they can learn and see more at InMoov.fr

Thanks!
