Following Birger T suggestions here is another expansion having the arms to the front, including a new grip design for you to 3D print. Do you want them for for boxing :D? Note the clip on the back is for the Bluetooth module ;*

Legs you can use Ottoky ones alternatively. they are outside the body without elevating the center of gravity

Next will be the OLED display as alternative to the LED matrix but there are memory limitations for it... how are we gonna solve that?

Did you ever think about magnets holding parts in place?

Birger T yeah i use sometimes in my own prototypes; magnets are good for makers but expensive and dangerous for kids unfortunately

I think is amazing this idea... will allow other actions

As to the memory. I suggest the every. It may be more exspensive but if you want to push the limits on an nano you can't beat it.

Hi Gerson Sena, did you mean the arms (or the magnets)?

hi Camilo Parra Palacio, hi Bill SCHONFELDER,

'cause the memory with an OLED - I thought, that it could be a 64x64 OLED, and when filling it with 8 x 8 dots or squares and with a red filter foil in front of it, it will primarily look like the LED matrix.
But there are more other features possible too - 3 OLEDs could be mouth and eyes, driven only by 2 IO pins - (And the eye's color wish may be solved by colored filter foils too ;-) ).
Next task to the core programmers should be, to handle the bitmaps ( as to call them directly from the loop - so unused bitmaps won't be included in the uploaded file ).

Exactly what I was thinking. With a larger robot body like a "bulk" you could add in two or three oleds. Then the question is, can the "every nano" handle that much graphics. Could a nano shield handle 3.3 volts x3?

Birger T the arms... but arms with magnetics looks nice too hehehe (for older childs)

Piers Kennedy you mean like no holes for servos, taking out also the inside clips for Bluetooth and slot for the led matrix?

For sure I can export something like that it will be like a separator and can work as a template for future expansions

Piers Kennedy Piers Kennedy I just uploaded the new .STL to this post, let me know if is as you want it. You can always extend if need higher.

If you have more modular ideas ask and we can make it 💪

BTW I use Fusion 360 for this type of precise things feel free to use as a template https://a360.co/3gOl8II but you can always ask me to export variations of them.

Piers Kennedy yes is compatible with V11 and V10 for sure I think is V9 and below that had smaller body and head size when the nano shields were smaller.

I was not sure what version number to put technically is the version 1 of that component but it seems is still confusing like this :D
