Control board for Colin my R2D2.   Very much a work in progress.

Sabertooth 2x32 and Syren-10 power boards mounted on a swing out panel.    I am also using automotive relays and and fuse unit.  Powered from a single 12-volt SLA battery for the moment but I have two batteries and it will be run at 24-volts eventually.

I am using the EZB control system.  I have managed to get the the EZB control system to drive the Sabertooth board, and that works fine.   Still having a few issues controlling the Siren-10 but getting there.  

I am using Eabels thingiverse Sabertooth/Siren card mounts and also the mounts for the panel itself.

I love your hinged multilayered electronics board.

I am building an integrated electronics board into my 2-3-2 design, now I won't be happy until it is as cool as yours. Lot's of designing to do..

Hi Martyman, been watching your 232 designs, very nice.  I think my multilayered board is a bit too deep at the moment so I may move the controller up into the dome. Then wire just the serial control back down to the electronics board.   Also I can connect a camera in the dome directly to the EZB controller.   Still planning it all...
I am wondering if it would be possible to design a book like arrangement where you can hinge out multiple "pages" of electronics. Maybe you could hinge one from one side and the next from the other side, and a third fixed at the back? But would make cable routing problematic? Obviously it wouldn't be as space efficient as what you have done.

I worry about serial communication over slip rings, just seems like a bad idea to me. Doesn't it fill your data lines with crackle as you spin it? But many people seem to do it with no problems.

I haven't seen the EZB controller before. It looks like it has plenty of inputs and outputs. Is it flexible enough if you have to use a graphical programing interface?
Hi Marty
Not yet tried the serial over the slip ring so will soon find out!  I think the padawan/Arduino control system approach is probably simpler but I have a few EZB controllers and it makes it compatible with my InMoov. The EZB certainly has lots of I/O and a camera connection.  I have now got the system running with a PS4 handset and the joystsick is controlling the Sabertooth/wheels setup fine.  Still working on controlling the Syren-10 motor-driver for the dome, however I may go back to my original idea and use a continuous high-powered servo instead, for the dome.  I need to print up a bracket for the servo. I have some HS-805B servos which hopefully will be powerful enough.

I also have a spare EZB controller so could have one in the dome and another in the main body.   They all wifi connect back to the main PC. EZB can be controlled as I say with a PS4 handset but also can be controlled by apps so iphones/ipads etc can have graphical layouts to control it.   Plus I am just now adding speech recognition and a chatbot service to it all. Thats the really nice thing with EZB, some of the add-on's possible.   Lots still to do but hopefully will have Colin [R2D2] and Nigel [InMoov] chatting together soon.

I am using the original "Front Vent Bracket" but I shaved back the support arms as the "Speaker Plate" was sitting proud of the body. I printed and tried out the Ninja top & bottom baffles version, but prefer this approach.   Its easier to take it all apart and very structurally solid.  

In the picture is my InMoov head which I am updating with a new neck mechanism and also better jaw actuator for speech.  Hopefully get them chatting away soon.  I have got basic AI working on both [pandora bot] but am sharing a computer so ideally need to have two discrete systems working.  Lots to do on that still, ideally a NUC or similar for each robot.

These are the DROK speakers mounted on the plate. 

Painting time!  Finally had a chance to get an undercoat on some of the parts.  Lousy weather at the moment so as I can only paint outside, its all a bit restricted.

Kyle watched your videos so many times that I find myself reading your posts in your accent! Love watching your updates..Thanks

Ha Ha, glad you like the accent! And the videos.
Hey Colin,
We have talked to eachother before about Inmoov.
Can I ask you what brand and type of speakers you're using  connected on the EZB?
Did you need to alter/hack the EZB?
I'm pretty new with electronics and have an EZB 4/2 now, but the sound that is producing with the internal speaker is not really great.
Thanks!
