Resurrecting Chumby as a master robot controller

Ro-Bot-X's picture

I have an old Chumby One that I wanted to use as a robot controller. GroG installed MRL on a USB stick and I had an external USB hub to connect the stick, the webcam, the Arduino and a Roomba interface. I'm trying to get rid of the USB hub, so here is the new setup:

- MRL on a partition directly on a larger uSD card in Chumby

- Arduino moved from USB-FTDI to hardware serial interface

- webcam directly on the USB port

- no more Roomba, different robot hardware

BeagleBoardBlack Service


Skeleton of Beagle Board Black service. Primarily this service will allow access through Java to the GPIO of the BBB.
Needs a Pi4J code to be ported to a BBB4J library ?  Project is just starting.



MRL, BBB importing Adafruit's BBIO .so modules

I now have MRL successfully running on a BBB ;-)

I have used python to test the Adafruit  BBB Python modules (linux shared objects .so) for GPIO and successfully switch LEDs on and off . (note need to run as root or sudo due to permissions under default ubuntu user.

>>> import Adafruit_BBIO.GPIO as GPIO

>>> GPIO.setup("P8_14", GPIO.OUT)

>>> GPIO.output("P8_14", GPIO.HIGH)

Proof Elves Exist !

Open any Linux executable binary up in a text editor - and the little guys have written ELF at the beginning of EVERY FILE !!!  (They started the rumor that this means "Executable and Linking Format" .. but we know better !

Thanks for the pointer GroG. I'm going to need all the asists I can get :-)

So here's the second tryat getting a photo up here:

This blog thing is all new to me. Hopefilly this will end up as a photo of my InMoov head and not a link to fliker :-)

Trouble Getting MyRobotLab Started

Dkelley's picture

Hi All,

I installed the latest Java and dowloaded and unzipped the latest MyRoboLab. I am running this on a Windows 7 - 64bit machine. When I ry to execute either webgui.bat or myrobotlab.bat I get the following message.

Could not find the main class: org.myrobotlab.servie.Runtime

I think that I am missing a fundamental startup step but I don't know what it is. Is there a step by step to get started.



First Print - Success !

Happy Birthaday GroG from all MyRobotLab users :)

Gael : " When I saw the video of Alessandro, I felt like InMoov had to do something too!!

Thanks Grog for all your help and your kindness!"

Andrew Davidson's Vision-Based User Interface - Programming In Java Book is Online and In Print

Andrew Davidson has a new book out which utilizes JavaCV and it looks like he covers a variety of topics. In the past I have found his writing entertaing, and backed by small, concise, and working code examples.
