open the servo see for burn marks

It's a bit difficault to get to at the moment unless I do a major disassembly of the robot. I don't want to do that just yet until all other avenues for remedies are exhausted.

Thanks anyway Patrick.

Looks like you've done as thorough a diagnostic as possible. It appears to be an electrical failure within the servo. A continuity test of the 3 leads might locate something or point to an internal issue.

@Steve G,

Did you try the old stand by for any Windows computer? Reset everything. Close EZARC, reset the computer, re-install ARC, start your Project, re-establish the WiFi connection, finish that beer, cross your fingers, then try out the servo control.

ah ok

Your servo is broken. What's connected to it?

Great eyeroll. It's connected as seen in the photo...

The head weighs about the same as a JD head so weight should not have been an issue.

It looks much larger, and has a metal speaker with magnet, and more plastic... visually it appears to weight more. I would assume your servo is not working because it is damaged. Easily replaceable Although I do recommend a larger servo. Those little guys are only good for a small amount of weight.

@DJ.

I take it you havn't seen my showcase then. The speakers (with magnets), battery, some of the internal plastic, and circuitry had all been removed, and speakers placed in to the robot body (as seen in my "making of" video in the project showcase). It's just an empty lightweight plastic shell now with the exception of two LED's, two sound sensors and camera added. I only had the thing working for two weeks before this happened. It may look bigger, but I assure you it's is about the same weight as a JD head.

I needed to use the micro servos because of space restraints so made sure of the weight as I knew that are not that powerful do using larger servos is not an option. These servos may be easily replaced, but I don't see why I should have to purchase another one when the one I have was used within its tolerance range and is faulty through no fault of my own. Besides, I'd have to pay extra due to overseas shipping on top of that.

hi steve G

are you using longer wires to get from the ezb4 to the head? are these wires all good.

@nomad.

Thanks for the reply. It does have one extention lead which I did check and replace (just in case) so I know that's not the issue.

@Doc and @oldrobotbuilder.

Thanks for the advice. I did what you both said but unfortunatly made no difference.

@DJ.

So could this be a manafacturing issue? Like I mentioned, I havn't used it that much, but the few times I did it, was working fine.

So after stripping the robot down to get to the servo and trying another to see if there were any issues, the test servo worked. I opened up the micro servo but couldn't see any visible burn marks on the PCB and all wires attached. I reassembled it to test it, but still dead.
