Finished head bob mech

Hi all, the head bob mech is finished and here is the result. I wanted the head to move forward a bit more, however, I had to sacrifice some movement for the strength of the parts. 

Using the lightdesk way for programming the moves...

Hello MRL InMoover's,

During the Maker Faire in Eindhoven (in The Netherlands) I was talking with Wilco about this option.
Both have experience with light consoles and know that the way of programming will makes it easier.

I've no idea if there is a option to use the same way of programming in MRL.
Now it's all done by scripts and most things are hard to make it smooth.
I mean, it's harder to combine some moves at the same time.

Advanced head bob mech Update

Hi all.  The movements have been finalized on the head bobbing mech.  Click MORE below to see the new video.   Spawn says that the running a script on the servos using the "servo" service makes the servos jitter during movement unless you use the -1 speed setting. Due to the weight of the skull (which will be added soon), he didnt want to burn out his servos using that speed setting.  Here is a look at the full movments before the rest of the skull is attached.   Any suggestions on fixing the servo jitter would be appreciated

If your gonna refactor the service - might as well make it "better" "stronger" "faster" ..

So I made it capable of input from youtube videos - cuz our robots will want unsupervised training of neural networks by watching tonnes of youtube !!

The above stream was done by a single line :



Yolo in conjonction with Ultrasonic sensor

So, I was working on a script to get Yolo starting only if an object is presented at the correct distance (1.0meter) using a Ultrasonic sensor.

This works nice.

Now is there a filter I could use to eliminate the background before Yolo analyses the picture?

@moz4r, I solved the neopixel issue by adding an extra sleep(4) at the beginning of my script.

If you would like to contribute to the workforce of building mrl - you can can run a "slave" building process on your computer with the following command :

Silence the InMoov Virtual Scream

I adjusted the initial rotation of the virtual inmoov jaw so that its no longer screaming, but in the same pull request I fixed the unbridled update.   What's this about ? 

JMonkeyEngine gives us a thread so we can update virtual inmoov, moving arms and head etc..  But if we don't slow this thread down the Frame rate will rocket to 300+ Frames per Second, which makes our computer not so happy :(
