Roli Rotation Servos Get Hot After A Short Period Of Time

Hello!

The rotation servos on my roli robot get rather hot after a short period of time (10 - 15 minutes) when they are not moving, and make a low humming noise, jolting through the 'dance' movement, it is not one smooth motion.
I just wanted to ask if this was normal, and if not, what can I do to stop this.

Thanyou for your time.

The servos are under constant strain when the arms are straight out, so they will get hot after a while. Since releasing them will make the claws drag on the tracks, the best thing is to find a good "resting" position. If they are pointed straight up it will provide the least strain to the servo to hold the position.

To add to what Alan said, I tend to find points in the middle of the range that okay for the servo to hold. No buzzing, no twitching, just resting without releasing the servo. I have a lighter arm though, so it is up to you to find the spot on your robot.

Actually, we've been meaning to update the app to put Roli in a more friendly position for his shoulders. I updated the app now, so please update your app as well. You can do this on mobile devices by pressing the Update Apps button. On ARC for PC, use the EZ-Cloud to download the latest app.

The updated Roli app will also be included in the next release of ARC.

Hello!

Thanks for the response, I have sorted the problem, putting the arms to rest in the upward position stops them from buzzing.

Thankyou for the help
