hello everybody

I have one problem with MRL and servos

I did everything correctly to move and control my servo with MRL but it is not possible , the Arduino is connected correcly and it is working just the servo didn`t move.

also I used this link and i recieved answer the same:   https://www.youtube.com/watch?v=AJasOtkCbro

any one had the same problem???????

Hello,

I happen to have at my hands a ranger finder lms500 and i want to use  the myrobotlab program to view its output, i know i can do that with SOPAS but my main goal is puting the laser on a P3-AT and then doing SLAM.
Can anyone help me with that? or show the way into how to do it on myrobotlab.
Thank you.

Hi,

we have some problems with our OpenCV2-implementation or library (we aren't so sure). We want our pictures to be exported as cvMat but at the moment we have no access to anything with cv2.anyFunction, so we get our pictures as IplImage. 

We want to continue with image procession with this format with cv2-functions in Python, that's why we need it.

Any suggestions how to get this started or even if it's possible to get it started?

Thanks in advance :) 

I am able to run version 1.0.099 MRL services on my Raspi 2.

With version 1.0.119 I can not set up the serial connections to my arduinos.

e.g. head.arduino - I set my mega 2580 arduino

head.arduino.serial: I select my port /dev/ttyACM1 or ACM0  but get only "no response"

Had another posting about this where I had the error "file not found" in the MRL log when giving commands to MRL. I assume this was a timing problem, the audrey file was not ready at the time the playback started.

There is also the fact that raspi 2 by default has no MPEG 2 licence. You can buy it in the raspi shop for 2 pounds, so only a small fee. Unforturnately this however did not solve my sound problems.

Converted then all audrey files to MPEG 1 format using WinFF. This helped to make all audrey files audible using mpg123.

So i just copied the code from mrl to the arduino and i keep getting errors with the TCCR0B, TCCR1B and TCCR2B.

After that i tried to include the mrlcomm library  in the code and it changed the error but i dont think this the way to follow for the solution. (image for reference).

Also i noticed that the tab for the arduino in my mrl is different from the one that i see in the tutorials.

here are  the images of the errors, so anyone knows what is the problem? 

life is good when you can turn at the waist

I have a usb camera attached to my raspi pi.

I can capture an image with
  fswebcam -r 640x480 i1.img

and display it wit
  links2 -g i1.jpg

When I start the mrl OpenCV service I haven't been able to get an image. But there are quite some settings available - what settings should work for me then?

Hello!

as i understand the Arduino Micro has 12 potential analog input.

i am planning to make a pressure sensitive (skin) on the forearm af Robyn with 12 pressure zones.

i need some help to get the analog input working on Arduino Micro  with MRL.

check out my test sensors

the Arduino Micro

I have my robot arms shoulder connected to be at the rest position (arms down) at 90 degrees. As I understand MRL uses 0 degrees for the rest position.

Had this question before and got as answer to set the rest position of my shoulders manually to 90 degrees with the command:

i01.rightArm.shoulder.setRest(90)

This however does not work after a reboot. I have tried to set the rest position at different places in the code but trying to set it before startRightArm throws an error and setting it afterwards only has an effect when I restart the python script.
