T-Hex 4DOF Leg precisions

Hi every one,

I’m actually building my first robot (T-Hex 4DOF) with my nine years old kid and the assembly guide is not always so clear for us.
To avoid mistakes could someone post a reverse angle picture of this one please ?

Thanks you very much for your help :slight_smile:

Many of the steps include an exploded view diagram. For instance, the one for that joint is:

Thanks but this scheme seems to be wrong, the ball bearing should be in the reverse position regarding my experience and this thread lynxmotion.net/viewtopic.php?f=1 … 7&start=24.
I just need to be sure don’t want to make any mistakes :slight_smile:

That post was specifically for the 485 servo. You’re not using 485’s are you?

The truth is the bearings can be used either way. You just need to make sure the washer goes in between the bearing and the ASB-04.

No i’m not, I’m actually using HS-645MG servos. But if i don’t reverse the bearing it goes out the C bracket and don’t do is job.
here is a pict of my leg :slight_smile:

Ps: I’m sorry, i’m totally newbie, so excuse me by advance if i ask stupide questions :slight_smile:

As I previously stated you can build the assemblies either way. When designing a set of brackets that will fit many different servos there are some tolerances built in. If the bearings fit better flange outboard then go for it.

Thank you very much for your help :°)

Maybe the C bracket needs to be “sprung” a little to add a little pressure to the bearing? (bend it?).
