Handy little app for Pi afficionados.

Humanoid's picture

I have found this little app from Adafruit to be really handy when I want to ssh into a Raspberry Pi but can't remember the I.P.  Works on most OSs.

This can be annoying when you have a bunch of them as a few of us do. 

Just click on 'Find my Pi' and it will come up with the I.P. for the near-by Pi.  

Use ethernet if it doesn't already have wifi up. 


status of openCV

juerg's picture

Hi Grog

Just saw in the shoutbox that you are working on distributed computing now.

Do we have a status of openCV?

At least the swing gui in version 2398 does not work for me,. Looks like a problem with window sizing as I can not get to the filter list on the screen.

Pi-Arduino Integration question

Humanoid's picture

On the subject of Raspberry Pis - for whoever knows about this:

I use two Megas to run my inMoov with MRL and (generally) Windows.  I am adding some wheels to the base and am considering throwing one of my pi family in there just to run the wheels, rather than use an Arduino Nano or similar.  I might even put a pi-zero in the head for some duties. 

BUT- it now occurs to me that, even though we have a Raspberry Pi service in MRL, the pi is a computer not a micro-controller. 


Setting up I2S Microphones on the Raspberry Pi 3 for NOOB's

Ray.Edgley's picture
If you are using the Raspberry Pi 3, one of the option is to use I2S (Inter-IC Sound) Micropones
 
This is diferent to I2C which  is for the control of devices and will be covered at a later date.
 
If you haven't already i suggest reading the Installing MRL on a Raspberry Pi3 for NOOB's
 

Problem with Tracking Service

Pasqui's picture

Hello,

I have a problem with tracking service in MRL. I uploaded the last available pyton script (.txt attached below), but i have errors like this:

Traceback(most recent call last): File string line 16 in ModuleAttributeError: org.myrobotlab.service.Servo object hs no attribute as setPin....

Someone can explain me how to proceed or can provide me with an updated pyton script?

 

deprecated speed settings

juerg's picture

Realizing how many script lines we have that use set<xx>Speed I thought of a workaround for the deprecated speed setting.

I am replacing all "i01.set<xx>Speed(...) in all py files with a call to set<xx>Speed() function.

I have added gesture files named set<xx>Speed for the parts that look like this:

def setArmSpeed(side, b, r, s, o):
  i01.setArmVelocity(side, b*15, r*15, s*15, o*15)

where 15 is the maxVelocity of the sub parts.

Installing MyRobotLab on Raspberry Pi

Mats's picture

Hi

I have seen in the InMoov forum that a few people are starting to use MyRobotLab in Raspberry PI, so I will share what steps I went thru. I'm not going to rewrite guides that already exists, but I will link to the instructions that I have used.

The first step is to get an operating system installed on the Pi. I installed the latest ( Jessie ) Raspbian using this giude: https://www.raspberrypi.org/downloads/raspbian/


Desperately seeking ideas re: large build-area, cheapish 2nd 3D printer

Humanoid's picture

It's come to my attention that my excellent Flashforge is not cutting it in the legs department. The build area is just too small for legs and other larger projects I'm contemplating. 

I don't want to spend mega-bucks on a second printer at this stage.  

Can anyone please suggest/warn about any 3D printers they've used with large build areas? I would like a fairly reliable one with a build area around 280mm/300mm cubed or larger. Preferably with a heated build plate. One extruder is okay.


Why this bot no worky? (Been away again)

Humanoid's picture

I have tried to run this chatbot on Windows with Chrome (no inMoov connected). I duplicated the Alice2 bot file and called it "ghostchat". When run this in MRL it opened webgui but threw an error. I modified nothing in the swinggui. Should I have? Everything looks different in there to what it used to when I last used it.
