Waist rotate biped - Question regarding head servo bracket

I was considering building the torso to give my bot head a home. I have not seen any clear-cut examples as how to mount a head servo in the waist rotate design.

Also, since I plan to use my custom bot head for this biped design, I am wondering about the strength of the ASB-06B.

My bot head, although fairly light, it will be heavier than normal. Is there a way to provide support for both the front and back of the torso?

Huh huh huh? :laughing:

Don’t worry about the strength of the ASB-06.
I just tried to bend my spare one and couldn’t.
I doubt that jumping on it would even bend it.
In fact… I’ll go try that.

Nope.
70 or so killograms accelerating at 9.8 meters per second (that’s almost 700N of force) doesn’t seem to harm it.

About the mounting…
Here’s an MSPaintCAD (hehe) image of it:

That’s the most convenient way to do it that I can think of.
However, if you don’t mind drilling some holes in the bottom of your ASB-04, orienting the ASB-06 vertically would probably center the servo better.

Wow Nick, If had not said you did it in paint, I would not have guesed! Well done!

As for drillin holes in the asb-06, I don’t mind, I take risk designing circuit boards, whats a few holes on aluminum… :laughing:

Thanks Nick, You rock. 8)

Now I never would have even thought to jump on the parts to test them for strength. :smiley: Yeah, the ASB-06 is made with 0.09" thick material because it has the potential to carry a lot of weight.

The drawing is close, but actually the ASB-06 lines up with the long side mounting to the ASB-04, so it does line up. No drilling required. :smiley:

Nick, your fired! :laughing:

Hehe, I guess that’s what ten years of sketching will get me, eh?

Everyone will just have to pretend that the ASB-06 is in the other direction.

:wink:
