General design and inspiration is credited to Matt of micromagicsystems.

The clear lexan is nice, all the components seem pretty organised. Good job!
That thar is Acrylic, not Polycarbonate. Check the smooth non blackend edges.

It is Polycarbonate. All hand cut.

Watha! I assumed it was laser cut acrylic. I knew it wasn’t laser cut Polycarbonate… Sorry for the misinformation. lol
Holy cow, you actually built that design! Quickly, too. Great job, really.
Did you cut the parts by hand with a scroll saw?

I used a Dremel with a fibre cutting disc to rough it out then finished them off on the Dremel router table. I deliberately made all internal corners so they could either be cut by disc or sander.

Absolutely great looking !!
Would you be able to post a picture of the Dremel equipment that did such beautiful work for you ?
Also, how long did it take you to cut all the parts after you decided on a design ?

The dremel I’ve got is the model 398
The router is
dremeleurope.com/dremelocs-u … rod_id=226
and the drill stand is
dremeleurope.com/dremelocs-u … rod_id=277
It took about 3 weeks in the evenings to cut and shape all the bits and pieces
Very impressive Dremel work. You have mad skillz. It looks like it was cut by a CNC mill.
Are you writing your own gaits? In the video it looks like you started a little wave gait there.

Yes, the gait is written in VB.NET and runs continuously to the SSC using command and query. The gait is generated using a token passing system.
Rather than having a gait generator, each leg is self managing and relies on tekens from its neighbour legs to decide if its safe to step.

What is your plan for getting that vb.net brain onboard?

errrmmm…
Well therein lies the problem… I have an Atmega128 I’d like to move the whole thing to, Servo control as well but I’m not too sure where to start. I know the SSC is Atmega based an one of the best. I might ask Laurent for a bit of advice…
Have you looked at the Nano-ITX boards? It would be easy to run .NET on one of those.

At 120mm x 120mm it is a bit large…
The Atmega 128 would be ideal with 7 ports, 4 of which could be used for control of 32 servos without having to use registers, 1 provides 8 seperate Analog inputs the other ports would provide 2 USARTS and digital I/O…
Unfortunately my C code isnt very strong so I will need to seek advice from somewhere…
True, but the pico-itx is only 100mm x 72mm. It’s expensive but very powerful for its size.

That would be viable. At the moment they are rather expensive though.
