I was running JD successfully last night, up until the time I had to put him on charge. Charged up the battery, disconnected after the charge. Tonight after powering him up as usual, I found one of the servo's (Port D5, his left 'forearm') was unresponsive.
Symptoms are: the servo doesn't move when instructed. The servo is able to be rotated by hand even when it should be 'locked' in place (similar to it's powered down state in battery saver mode). There's no change if I place him in the 'calibrate' position. All other servo's are in their normal calibrated position.
There was no smoke and no buzzing from the servo last night prior to powering JD down. I have disconnected the servo from the port and reconnected it as well. There are no obvious signs of the wires at either end being frayed or unusual.
I am wondering if there's anything else I can try, or if this is an indication of a dead servo? I received JD just over 2 weeks ago.
Any advice would be appreciated. Thanks.
@ DJSures - The ez-robot servos have unbranded Mosfets in them.
And this.. "The servos are great still - only people with an issue will post on the forum. So, the one user per month with issues is pretty good" is not true. Unbranded Mosfets are a curse in the electronics and robotics realm and I am extremely disappointed that you would support them as there are branded Mosfet servos available for the same price as yours.
Since two of my servos have died, I replaced them with branded Mosfet servos and regardless of my extra long arm have had no problems what so ever even though V9 has been rocking me out to one of her favorite trance tracks for the last month -video upon request! There's no excuse for a servo to freak out over a three servo stack or a three-second jam.
Dealing with China successfully is a road filled with landmines and I implore ezrobot to seek out a better and branded Mosfet deal as soon as you can. Seems to me you have a big reputation to keep and that will be hard to do with crappy servos.
