Bad Servos

The Revolution Six robot I purchased has loss six servos and can no longer move with assistance and makes a lot of gear grinding noise. I ask about it the past but never heard back on it. So I am asking again where and how to I replace the defective servos on the robot? For the amount paid for the robot it is a sad fact for it just to sit and the shelf collecting dust.

The ezrobot HD servos aren't very likely to strip due to being all metal gears. The issue from the video seems to be intermittent contact. It could be as simple as the servo is not plugged into the ez-b far enough or it could be that the connection where the wire enters the servo is frayed.

@jfew Thanks for the video, another test you could try is touching the problem servo to see how hot it is compared to the other servos.

On an unrelated note, @Richard R not seeing your Fry avatar threw me off, lol.

@Jeremie Well, I thought I would show my artistic ability and use a picture of an inMoov I drew when I was building Andrew... You know, as a build aid of sorts....:P

i think putting the wires thru the holes of the brackets is not so good idea.

@nomad TMBS great observation! I can't believe I missed that.

@jfew unfortunately because you ran your servo wires through the hole in the servo brackets, the servos themselves are likely are tugging their own wires right out of the servo causing intermittent contact to the servo electronics. Or the wires are getting pinched between the body of the servo and the bracket.

Please change the way the servo wires are run back to the standard configuration.

I missed where he ran the servo wires too.... Nomad has good eyes.... Anyway, where you routed your servo wires most definitely I can see would cause either the servos to bind or wire connection problems... My guess from the sound in your video one or more of the servos have stripped the plastic spline in their bracket housing....
