AdafruitMotorShield - what the what ?

GroG's picture

I'm running the Test service which whips the auto-magic elves into looking in every nook & cranny for little bugs.  They found lots hiding in AdafruitMotorShield.  

I don't think its worked for years :P 

It relied on code being "injected" into MrlComm before being compiled and uploaded.  It also required the AdafruitMotorShield library to be included/compiled into the upload.

So how to get AdafruitMotorShield worky ?

Manipulator video

This is one video to see manipulator is working. You can see proximity sensor to take something.


Mpu6050 Service


MPU6050 is a service for Accelerometer and Gyro. Several different boards exists that has the MPU-6050 circuit. Different boards can be found at the Arduino site The board that has been used for testing on both Arduino and Raspberry Pi is the GY-521 board.

This my manipulator:

Hardware are arduino nano, 6 servos, 5 micro switchs and one proximity sensors.

Software is MrlComm, powered by MyRobotLab.

I always get the erroer message bad magic number when ever i alid the slider for the servo.

I am using the latest build.

Oh and every time i slide the slider my arduino disconnects


LocalSpeech Service


This text to speech synthesis service use local operating system text to speech engine.

MacOs :

Just set your voice, inside control panel
You can test it using say "something" inside terminal

Hello all,

Get your printers warmed UP!! The legs I had created a long time ago for InMoov are ready to download.

Remember this modele is only for standing, I'm still working on the motorized version.

moveToBlocking() for scripting

It is useful, to wait a finished moveTo() before to launch another. Without using a sleep(x) between 2 actions. because sleep() didn't take care of servo speed .
The magic will worky only if velocity > 0

There are several levels :

1 servo blocking event

On the arduino nano, i have strange behavior with setVelocity.

I have a big difference between setVelocity(50) and setVelocity(-1)

setVelocity(50) is very slowly.

Is it normal ? 

Is this correct with old speed function ?
