Use the merge option to load specific skills into a project: https://synthiam.com/Support/ARC-Overview/loading-saving-robot-projects/Merge%20Project

for auto position, there’s import and export options in the configuration menu.

either of those options work for your requirements as needed.

Great , thanks

You're welcome! If you have any more questions or need further assistance with Synthiam ARC, feel free to ask. Happy robot building!

i will try the merge option at the next freeze

If you're having freezes, that's not good. Do you have any scripts that loop to call the same script? Or stuff like that? Because ARC is generally incredibly stable, you can always share your project, and I can quickly look at it. But without knowing any details, I cannot give much advice.

I loaded the JD example with 12 controls and i modified the project to my needs,add scripts,servos,bing,autoposition etc... at this time i got some freezes. I thought my project file was corrupted and i started it again. I got again some freezes. So i decided to start from scratch. I started ARC with no project and I add the skills one by one. I have worked this afternoon a couple of hours by adding skills to my project, currently 9 skills.... and i got no freeze! 2 skills are not yet included , camera device and RGB. I will add them soon. I purposely didn't install the camera and RGB because once, I saw a message on the camera window indicating an I2C message. dont remember exactly the message but i2c was written. Maybe a problem with i2c?? I will add the camera and afterwards the RGB skill.

I'm sorry, but that still doesn't help me to help you. I will either need the project or very detailed information about scripts and such. You're doing the right thing by debugging though. Keep adding stuff until you find what gives you the error.

An i2c message would be RGB led eyes. I would make sure your cable connections on the led eyes and camera are secure. They loosen over time. I think a drop of hot glue would prevent that.

part 3 of this document would be useful: https://synthiam.com/Support/troubleshooting/EZB-Disconnecting

I checked your debug log and this is the error...

2025/01/28 18:15:44 +01:00 System.Exception: Capability 'I2C Master' is not supported on this EZB device.

Thats because you were trying to configure the robot skill for the RGB eyes when no robot was connected. The error message states that the function doesn't exist - and that's because you're not connected to a robot.

That error would not lock up ARC.

thanks for your help. ll keep working by adding skills.

I always thought of merge as a closely guarded secret, helped me out so many times!
