Thanks Gael, it’s great to have your personal input, this is such an incredible project. I think I’ll take your advice and stick to the original design, I wasn’t happy with the way that thumb joint printed anyway. Do you have any suggestions as to where to source the springs? I’m having a real problem trying to find any. Also, what is their o…[Read more]

Thanks Mindless, it was just looking through Gael’s instructions for the forearm build, he seemed to have 4 holes in the side which you have to redrill and put the bushings from the servo in. All the files I’ve found so far don’t seem to have those 4 holes and I don’t know where to put them.

  You have to make a choice, either you use an extra servo for thumb or you set the spring tensioner. Both are to be set at the same location.
  Personaly I was never thrilled about that extra thumb actuation, because the demonstration videos I had seen didn’t convince me.
  But regardless, you can still attach the servo, there is holes to set three…[Read more]

Just getting started out, I’m really looking forward to the whole adventure of building this, I have been teasing my 17 year old son that I’m building a replacement son for when he leaves Home.

I’m just having a bit of a problem with where to fit the extra servo for the articulated thumb, I can’t find a rob part for the arm with the extra 4…[Read more]

Hay Simon ,,,Last time a looked at the articulated thumb by Anar it is just a manual adjuster with no Servo based movement,,,,
