Getting started with myrobotlab - Having problems? Ask the nice people here.

So I am wondering if I have to use java to add a new motor controller?

I am using a dagu 4 motor controller that uses two inputs for each motor, pwm and direction, and it also offers encoders and current sensing for each motor

Just curious as to how to add a new controller.

I was wondering how hard it is to add new arduino boards to the mrl arduino service.

I am using an UNO right now, but only because I can't use the Modern Device RbbLeo, which is an arduino compatible Leonardo board.

Is this something that's hard to do?

Ok, I have succesfully used MRL on my desktop computer, and now I am trying to get it loaded and running on a netbook that I plan on using MRL with to power my bot. 

I am having a strange problem..  I can get MRL started, after an install of the latest java SDK, but, when I try to add new services i can't, See my screen shot that i have attached. 

Just a little post to say there is an empty script in the list .

It's the script " Face tracking " under " vision " submenu

I was trying to become more aquainted with MRL as a user and had some questions. I thought I would create a thread to save the answers for posterity.

First, I was trying the keyboardinput example (HERE). Long story short, it doesn't seem to work. Being unexperienced I don't really know why. It appears input() is never being called, but the keyboard commands appear in the java window.

Upon executing the example I get the readout below.

 

Hey Grog,

Thanks for implementing the new Serial service based on my previous request,

I want to use this service for my robotic chess project.

I have an arduino connected to the PC and I am able to connect it with MRL using Serial service, but when I am sending a string  from arduino I am getting its ASCII value on the log file.

Could you plz help me on how I can get the proper string into MRL from arduio.

Thanks :)

Hello,

I've tryed to control a led on my arduino with voice based on the python exemples from MRL ( arduino ouput and talkback) , and nothing happen, i've just an error . But i just starting to learn python and i don't see the problem . Could someone help me ?

Or perhaps, all is wrong lol ! If it's the case , i'll retry from start ...

 

Thanks

 

This is the error returned by MRL :

So I'm new to my robot lab but I've been tinkering around with it for a while. I've noticed that after I updated my MRL version that my arduino doesn't respond to changes in the arduino service when I try to set the outputs for any of the pwm pins. It seems that the service isn't even telling the arduino to output through these pins because the rx indicator light doesn't blink when I update the values. I'm not sure if this is just a case of my version or if its no worky. Any insight would be greatly appreciated
