Mike's BRAT - (SN96) - New VIDEO

Jim,

Can you tell me what bracket(s) you used to allow for a pan servo like in the pic below?

Here Is my BRAT chassis:

Forgot to get some feet. It is footless for now.

Seems to me it uses:

custom made “C” Bracket with 4 mouting holes
multi-purpose servo bracket
L Bracket to attach multi-purpose servo bracket to the 3u-channel.

I think the L bracket is attached to the center hole in the u-channel, but on the multi-purpose bracket it is attached to the one closest to the servo horn side. This way the camera is centered.

I wont be needing the “C” bracket with the 4 post. I think if I use an “L” bracket mounted on top of the channel and then mount an ASB-04 would work.

That would also work, but it may limit the maximum rotation angel of the sensor. The lower part of the “L” might hit the side of the servo when turning. Otherwise it should work. If you dont have any extra L brackets, getting a pack would be better than a pack + C bracket. Cheaper that way as you get two in a pack.

Looking at the photo, I would say that the C bracket looks like a standard deep one, and the camera board standoffs are straddling the metal closely enough that screws with washers are sufficient to ‘pinch-mount’ it to the bracket. Since the camera only weighs an ounce or two, and isn’t a structural element, that’s probably more than sufficient to provide a rigid mounting for it.

isn’t it just an asb-04 bolted to the ec-02 carrier and then a asb-05 long c bracket to support the camera?

and now I know why you didn’t want the feet I offered you… you went shinny instead of stealth. got to say I am amazed you managed to forget to buy a set though… given how much we were joking back and forth about it. :unamused:

I bet that was all a scheme for him to show us some super-cool, custome feet he came out with in Alibre Design :imp: :smiling_imp: :smiley:

Nice BRAT mike :smiley:

i cant wait to see what ur finished product will be like

eddie in this case black is not stealth, the shiny feet will blend in with all the other shiny stuff us roboteers collect, black would stick out xD

Alright Eddie, I deserve that. :laughing: I could have swore I had it in the shopping cart, I guess I put it back on the self and for got. :open_mouth: :laughing:

Anyway, I am not looking to mount a camera, I want to mount the bot head if it does not make it to heavy for the 422 servos. I want to give it a shot anyway.

I think an ASB-04 with an ASB-06B mounted on the channel will be ok.

I’ll add those in with the feet :unamused:

No custom fab? Cmon Mike, show us your skill :smiley: 8)

Did you say Skill or Skull? :laughing: :stuck_out_tongue:

:laughing:

okay… maybe he’ll show us how to tin electroplate the servo cases then so they blend too. :stuck_out_tongue: :wink: 8)

I’m not building a stealth bot :unamused: :laughing: . I chose shinny parts to match my shinny bot head. :laughing:

uh, ok, shiny bot with black servos. :wink:

I changed my post to avaoid any possible problems. No harm intended. :smiley:

I mounted the electronics to see how it looks and it looks cool. I wish I had a box full of various brackets to experiment with different configurations for the head servo mount. Also, I think I might just get HS-5645 servos so that I can use them in future projects.

Very interesting read… I can see now how helpful illustrated assembly guides are. Maybe we need to try and make some 3D exploded views for some assemblies that do not have assembly guides for. The ASB-04 is attached to the middle of the ASB-503 by way of an ASB-18. The ASB-06 may work, but I can’t say it will look the same as my method. Yes Seamus, the camera mounting holes lined up perfectly to fit on the standard ASB-10.

Jim, I must admit the tutorials were fantastic and the fun factor assembling all the brackets was from a scale from 1- to 10 – it was an 11 for me! It all went together so well that It was all over before I wanted. I could do this kind of thing all day long.

As I was looking at all the parts, I was amazed at how ingenious the concept really is. It all goes together without a hitch but yet a completely new design can be made using the same types of brackets with out bending, cutting, or drilling which is the part that amazes me. The quality of the screws was fantastic and made fastening them in hard to reach areas a bit easier.

It all seemed to just fall in to place and there was nothing frustrating about any part of the assembly process.

Jim,

I have another question for ya regarding the ASB-18b and the order of which you assembled them:

Hey wow extreme closup and it’s in focus. 8)

You just mount the ASB-18 then the electronics carrier. Here is an image.
