I'm little lost ... bear with me:

if you start from the begin:

1. EZB off, servo off
2. Connect servo to EZB port D0
3. Connect power to EZB (i assume you are sharing power between EZB and the servo, if not please explain)
4. Open ARC
5. Connect to EZB
6. add the following script:

#signal initialization required for Kondo PWM servo
Set(D0, 0)
Sleep(600)

#Testing positions
Servo(D0, 1)
Sleep(2000)
Servo(D0, 90)
Sleep(2000)
Servo(D0, 180)
Release(D0)

7. Run the script

Q1) Does the servo move to 3 different positions and is released ?

Q2) If is not working, what is the working sequence (starting from step 1) ?

here a video for you: https://youtu.be/n4p_hYNmKy4

only with this magic trick moves the servo

Please do not make duplicate threads for the same topic.

@DJ Sures

but nobody helps and this thread is closed and the problem is another..

People will respond to this thread if they have something to offer. Currently, no one knows anything about these servos. This thread is the best resource for those servos if someone has a suggestion. I don't have a suggestion either.

What I get from watching the video is that the servo works if it is connected with a PWM immediately provided on the signal line.

I guess the only suggestion i have is to separate the power from the signal. Connect the servo signal wires to the EZ-B. Connect the power wires to a secondary switch.

That way, you can initialize the PWM for the servos and then switch the power to the servos.

Have you attempted to contact the manufacturer of the servos and inquire how to hardcode their operation to PWM mode?

Lastly, the alternate is to research the UART protocol for the servos and create an ARC skill plugin. If someone found an actual protocol datasheet for the servos, i could assist with the plugin. It would be an easy plugin to create with a proper datasheet.

I found this: http://kondo-robot.com/w/wp-content/uploads/KRS-series_manual_Download-En.pdf

and this: http://kondo-robot.com/archives/faq_category/ics_dep

ha, i think this is supposed to be the ICS protocol datasheet: http://kondo-robot.com/w/wp-content/uploads/ICS3.5_3.6_SoftwareManual_2.pdf
