hi the community,
i have build JD,i have initialized the servo and i have tested JD it work a few moment and after the servo of the arm stop to work and they don't move i have tested on another port and the servo not turn,i have changed by the new servo and they have work also a few minute and the same problem.could you help me
thanks
Are you using an EZ-Robot Lipo?
Are you using EZ-Robot HD servos or HDD servos?
Or are the servos not from EZ-robot?
I also suspect the mg996 are Chinese knockoff because those are one of the most popular servos to knock off. Meaning they may not even meet the datasheet specifications.
The servos are being damaged by the lipo voltage. The datasheet for the mg996 servos is available online with a google search.
My thoughts on fixing the problem are:
If that was my robot I would (Option 1) consider upgrading all of the MG996 servos to EZ-Robot HDD servos or alternative servos rated for up to 7.4 volts
OR (Option 2) you could add voltage regulators to each of the mg996 servos to bring their voltage down to either 5 or 6 volts.
OR (Option 3) you could look for a 6 volt lipo that is bigger than 1300mah but also the same size dimensionally as the EZ-Robot lipo that way your battery won't exceed the voltage tolerance of the servos.
Your JD looks fantastic BTW! Great job!
