Nice prize! I am sure that you will enjoy your new toy (I mean project).

Congratulations [mention:d25512d61e65470296ce2f82f47741ab:e9ed411860ed4f2ba0265705b8793d05] on winning this cute robot ... I can see with a 3D printer you can add more to Marty. Like a laser gun to his hand [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-62b575fe-9c2f-4a6d-b23a-0de046e06242/contentimage_5F00_3.png:16:16] keeping in mind the servos should be able to pull up the new weight ...

Great progress, Dubbie!

You could save a bit of space by using a Digispark or Pro-Mini board insteady of the Nano, some of which are available in 3.3v models too.

Squeezing the battery in will be tricky, but maybe using a little pack from a toy helicopter would give enough run time.

I've also seen LifePo4 batteries in AA (and AAA I think) format with a nominal voltage of 3.2v and a fully-charged voltage less than the maximum allowed on those boards - meaning you wouldn't even need a boost or regulation circuit.

You might end up having to 3D print an internal skeleton to neatly fit all the pieces!

Before you design that, play a few rounds of Tetris [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-22802961-d7e3-4680-8909-272c309ae7de/contentimage_5F00_3.png:16:16]

That's so cool!

I'm always impressed with how perfect your 3D print designs come out - I still need to figure all that out. Did the design/CAD work take a long time to do?

And also... did I hear you say you found a limit to the uses of dollarstore fingernail polish?? [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-b2711d50-27f6-4f25-a6a9-94bd7574b8e2/contentimage_5F00_3.png:16:16]

Great project. I am really impressed with the fit you get from the 3D printed parts.

I do not know what is available in the US but in the UK we have little pots of enamel / acrylic paints from Humbrol, Revell and Tamiya along with modelling paint brushes of different size and shape. These are popular with plastic model makers but it probably takes as long to do the painting as it does to print the parts off.

Kind regards.

A fantastic build. There is an R2D2 builders club, I guess they would have some details (or would be interested to hear about your project)

That's very cool - love the idea of aerosol can cap robots : )

Wow - very good looking R2D2!

Douglas,

A detailed design, the CAD work must have taken an extremely long time. I particularly liked the way you have incorporated an existing product (the speaker head) into your design. I might try something like that, it looks fun. I also like the way you have achieved the rotating head as I have played around with similar things for some time and not managed to achieve a satisfactory rotation effect or the stability you seem to have. The servo axles are not really designed to take a heavy weight and they tend to flop around a bit.

Great little robot. Could you power this from a tiny Lipo or even a super cap?

Nice! But what happened to the spray can tops? To save space, you may look at IR sensors which would basically look like eyes on the tiny bot.
