beetlejuice's picture

Hi everybody,

Sweety's printed arms are almost finished, and so i'm starting to modify . When trying to start servos, i get this error for each servos : 

error can not create peer from reservedkey sweety.rightShoulderServo - no type definition !

InMoov knee actuation

This my latest refined knee model which is running with the service DIY Servo.

I love that service by the way!! Well let say, I just love MyRobotLab!

It's incredible the evolution it has under gone since I started this project.

Before everyone starts to break it after the Manticore, I am asking Santa to implement velocity in that service to see what is smoothness of movement on payload, and if it can still control with enough power.

Ahoy ! FaceRecognizer was worky great, every time. ( I'm using SarxosFrameGrabber ).

Tested new unicode support, seem worky great ( I crashed for an other reason : )

I decided to switch to OpenCVFrameGrabber, now FaceRecognizer is broken, like Gael report :

Network chatbots to use instead of local Program AB

Konstantin's picture

Hi guys!
The AIML based Program AB seems to be quite old and obsolete technology nowadays.
Training is difficult, and AIML base like ALICE is hard to find in any lang except english.
Building up from scratch is crazy.
Is there plans to add to MRL support of modern AI APIs eg (DialogFlow) or similar?

audio signal sync not work

sunilskar's picture

Hi Inmoov core team,

I update the latest build from myrobotlab. and want to use audio sync with mp3.

I change the following code true in " skeleton_head.config "

;this is optional direct mouthcontrol
;analog pin range are 14-18 on uno, 54-70 on mega

but it will not work anyway and also if we on this tab it will stop mouth servo working .

how do I use rest api in MRL?

juerg's picture

I am trying to use the rest api to move servos or have the robot say something.

Found some examples but failing now to make it work.

e.g. having a tab in MRL named "i01.leftArm.bicep" what url will move it to 20 degrees?

tried things like this:

but get:
IOException, invalid api: services

Setting servo speed in Arduino and Python

Humanoid's picture

I have always just used my servos at the servo's full speed. 

This is a problem when setting servos if something goes wrong. No reaction time before breakages occur. 

Q1) For stand-alone Arduino - Is there a line of code I can add after "servotest.write(90);" to lower the speed of servo movement even to a quarter or a half of normal speed or is this too simple?  I have been using the delay() command but I gather that doesn't affect the speed of movement only the delay between movements.
