I am using AL5A robot arm for my project… It is having some problem.whenever i connect the gripper pin to the ssc-32 board,the whole system stops working and gives a very slow and weak movement. How do i solve this problem? it uses Hitec HS-422 servo motor
I’d suspect the battery. What are you using?
That servo could also be bad.

i am using a fresh 9v battery…If the servo is bad,how do i rectify it?
Pretty much sounds like the 422 has been damaged. Try replacing it.
is there any way of servicing it to make it to work???
Based on your description when you plug it in it draws too much current. This is drawing down the power supply causing all the other servos to not move correctly. This sounds like the PC board inside the servo is damaged. Not worth trying to fix it.
I don’t suppose the 9V battery is the ONLY battery supplying the SSC-32?
You would normally have a battery for the servos (6V), and a 9V battery for the electronics. Check in the assembly guide. But a “fried” servo would kill the power, as we’ve indicated. Getting the same results with all the other servos removed would be a good indication of a fried servo. But check what voltage you’re supplying to the servos! Too high a voltage will fry more…

I use two supplies 9v battery and 6v from the adapter. I supplied the right value of voltage…how come only one motor gets fried and the other stays fine?
If the gripper were to be commanded to close too tightly on an object the motor driver inside the servo could blow and draw too much current. This could happen without you even knowing.
I think you nailed it!
