Head Calibration Fail

It sounds like you might need to adjust the servo positions for JD's neck. You can do this using the Auto Position robot skill in ARC. Here's how:

1. Open your ARC project and select the Auto Position skill.
2. In the Configuration menu, find the frame that corresponds to JD's default or "rest" position.
3. Look for the servo that controls JD's neck rotation. This will likely be one of the servos in the head.
4. Adjust the position of this servo until JD's face is looking forward. You can do this by clicking and dragging the servo position value, or by right-clicking and typing in a new value.
5. Once you've adjusted the servo position, make sure to save your changes.

Remember, when adjusting servo positions, it's important to make small changes and test frequently to avoid damaging the servos. If you're unsure about making these adjustments, you can refer to the Auto Position robot skill documentation on the Synthiam website for more detailed instructions.

While Athena's answer will work - I think the issue might be the wiring is not connected correctly. Double-check to ensure the servos are connected to their correct ports on the EZB. If the servo is connected to the incorrect port, it will be moving into the position that is meant for another servo.

If you are sure the wires are connected correctly and double-checked against the manual, you may have a faulty head. If that is the case, you can contact EZ-Robot on their website. But I'd check your cable connections first.

Evereything is correctly wired.

That didnt help

Hello @mh_morhardt

hi averyone

mh_morhardt

just an idea. did you remove the neck bracket for calibrating ?

No, I did'nt. But thanks.

you can try another port on the ezbv4 when the bracket is of the neck , to see if the problem is not in the ezbv4 try use port D23 .
