I am writing to request assistance with a Dynamixel AX-12A servo that is not working properly.
I have been using this servo in a 6 DoF robotic arm, as the third servo in a chain. Recently, it stopped responding to commands. All other Dynamixel AX-12A servos in the same configuration continue to operate normally.
For power, I use a 12V power supply. And for communication, I use an Arduino MKR Zero + Arduino Shield board.
I tried to perform a firmware reset on the servo using Dynamixel Wizard 2.0, but the procedure was unsuccessful. The program stopped and nothing happened.
I would like to request guidance and on how to perform a “Firmware Recovery” for the Dynamixel AX-12A. I believe the firmware may be corrupted and this may be a solution to the problem.
Thank you in advance for your attention and support.
