How to add the Darknet YOLO (Obj Detection) robot skill
- Load the most recent release of ARC (Get ARC).
- Press the Project tab from the top menu bar in ARC.
- Press Add Robot Skill from the button ribbon bar in ARC.
- Choose the Camera category tab.
- Press the Darknet YOLO (Obj Detection) icon to add the robot skill to your project.

How to use the Darknet YOLO (Obj Detection) robot skill
You only look once (YOLO) is a state-of-the-art, real-time object detection system. using Tiny YOLOv3 a very small model as well for constrained environments (CPU Only, NO GPU)
Darket YOLO website: https://pjreddie.com/darknet/yolo/
Requirements: You only need a camera control, the detection is done offline (no cloud services).
- start the camera.
- check the Running (check box)
The detection will run continuously when the detection results change an On Changes script is executed (check the configuration area):
- Press config
- Edit the on changes script
- on changes Javascript script
you can run the detection on demand, javascript:
controlCommand("Darknet YOLO", "Run");
The above command runs the configured on demand script.
An example of script:
var numberOfRegions=getVar('$YOLONumberOfRegions');
if (numberOfRegions==0)
{
Audio.sayWait('No regions found');
}
else
{
Audio.sayWait('Found ' + numberOfRegions + ' regions');
var classes = getVar('$YOLOClasses');
var scores = getVar('$YOLOScores');
for(var ix=0; ix {
Audio.sayWait('Found ' + classes[ix] + ' with score: ' + (classes[ix]*100) + '%');
}
}
Hi,
I have been using this skill for some time and I am very glad that you created it! I do have a couple of questions:
It's not possible to use multiple datasets in a single inference process.
Can I port the On Changes Script over to EZ-Script, Blockly, or Python, or is only JavaScript supported for this skill?

There's a standard dialog for editing scripts - it's the same editor in all ARC scripts. You can select the language you wish to use by a tab on the top. There's more information on this page about how the script editor works and languages: https://synthiam.com/Support/Programming/code-editor/edit-scripts
Scroll to the bottom, and you can read that relevant section of the page. You can use the support section to find additional information about using ARC.
*edit: or this step of the getting started guide is quite popular: https://synthiam.com/Support/Get-Started/how-to-make-a-robot/choose-skill-level
So I assume you meant that just because the "On Changes Script" was written in JavaScript, it could have just as easily been written in the other 3 languages. I had assumed that there was JavaScript code used that would not work in the other languages. I guess I could have tried rewriting it myself. I've been a bit overwhelmed trying to get the last two Simone articles out.
Thanks.
Yeah, that's precisely what you'll have to do. Why would you want it in another language? The Javascript compiler is 100 times faster (or something comparable) than ezscript.
