Good evening, I assembled the PIDOG. At first, it seemed to work. By running servo_zeroing, the servos would zero out. Unfortunately, this only worked a few times, and then the servos stopped moving. I changed the Raspberry, same thing, and then changed another Raspberry, but the servos don’t move and remain unlocked.
The battery is fully charged, the charging light is off, and when you reset them using the mains button, they reset and lock.
I think my Pidog will never work, and I’ve wasted my money.
Thank you for your detailed message, and I’m sorry to hear that you are experiencing this issue.
From your description, the PiDog was able to run servo_zeroing successfully at first, which means the servos, the Robot HAT, and the software were all working properly at that time. Therefore, we believe that the PiDog may not necessarily be broken, and we would like to investigate further before drawing a conclusion.
Could you please help us check the following?
Run the I2C detection command on your Raspberry Pi (after booting) and send us a screenshot of the output:
i2cdetect -y 1
When you run servo_zeroing, do the servos make any sound (e.g., a faint humming noise)? Or is there absolutely no response?
Record a short video showing:
The PiDog’s status when powered on
The process of running servo_zeroing
The current behavior of the servos (e.g., are they completely loose and can be turned easily by hand?)
Please share the video with us (e.g., via Google Drive or OneDrive).
These details will help us determine whether the issue is related to power supply, Robot HAT communication, or the servo control signals.
Please don’t worry – we will continue to assist you and do our best to help get your PiDog back to normal operation.
Thanks for the reply. Today I unplugged the RGB strip and it’s working now. I don’t know if that was the problem, but it’s moving for now.
Thanks
