Board looks good!

Is it single sided?

Yep! I'll be drilling the holes and soldering the components on tomorrow so I'll upload another photo when I'm done. :mrgreen:

Hi everyone! Sorry about not updating but I've been pretty busy (university interviews and stuff :mrgreen:) but I have made a new B.A.O.U.S Board - I realised that V1.0 was printed on backwards so it wouldn't have worked :oops:.

Anyways, the new board is all nice and proper and I've finished drilling the holes and I'm soldering the components as we speak - here are some photos of the new board (it's smaller than the other one as well; measures about 8.3x5.3cm). Enjoy! :mrgreen:

Here's a photo for size comparison of B.A.O.U.S Board V1.0 to V2.0. :mrgreen:

P.S. I ran out of solder :cry:, so I'll have to stop for now and buy some more tomorrow.

I've finished all the soldering for the board and I think it looks pretty decent :mrgreen: - I'll upload a photo of it in a bit but at the moment I'm having an aesthetics problem:

What kind of colours should I use for the Mantis robot? The current colour scheme for the legs is BLACK/RED so I need something that goes well with both and I would love to have some opinions about this. The colours I can choose from are yellow, red, black, blue, green. Here's a photo of the pieces of plastic:

Hmmm...Yeah, that's pretty cool! :D
I'm just trying to visualize the colour sequence for the robot brackets. :mrgreen:

i know you cant really "mix" the colours but it would look cool if you could.
Just a quick idea:

That's very nice and thanks for the comment! :D
I may not be able to mix colours but what I'm going for (well, trying to go for) a lot in this project is having multiple colours in the different brackets - the photo below should hopefully explain what I mean:

I've been experimenting with various designs for different parts of the robot and I've currently got this design for the arm - it's a bit unorthodox but it's only a design so modifications will come :mrgreen:.

Also, since the Mantis uses its legs and arms to walk, would I have to try to make the front of the arm a suitable shape so it can walk properly or could I leave the heavy walking to the 4 legs and use the arms and brief support for the movement?

P.S. The shaded parts of the drawing represent the parts that will be replaced with cut-outs of different colour. :mrgreen:

I've managed to sketch the general shape of the head and I'm working on some nice eye designs to make it look awesome - I think I might line bend the head through the centre to give the inner angle as being about 150 degrees or so. I'll cut it out tomorrow and experiment a little. :mrgreen:

nice idea.
how did you manage to mount the two colors together?

did you cut the outline (negative) into the black part and then cut a (positive) from the red and push or insert the red into the black?

Yep. I did exactly that; cut the outline out in the black and then cut around the red pieces to make them fit. :mrgreen:

I managed to get a fair amount of stuff done today (in the means of cutting out brackets) - I made the main torso and the 4 servo brackets required for the arms (2 servo brackets per arm).

I managed to start experimenting with the head design as well. It's going to be made up of multiple layers; each of different colours and so far I have the first layer (the basic front face) completed.

Here are some photos! :mrgreen:

And you're able to bend the 3mm Acrylic plastic for the Arm Bracket? Using temperature?

Great job!

How do the Acrylic brackets hold up? How well does it bend?
