Size Matters Not - An R2D2 Story

13 Feb 2019

R2D2 is a monumental icon regardless of its physical size - that has meaning for a large number of people - one of the most popular characters who has no speech.

I have been planning for quite a while to build an R2D2, but every time I took a concrete step towards that goal it seemed to look harder to achieve something reasonable.

This entry is using A Question of Scale as an excuse to move this mini R2D2 project out of the planning stage and into a build phase.

It is great to finally get around to another project from my bucket list. This is definitely a scaled down version of R2D2. I could not find appropriate dimensioned drawings so I tried to take measurements from various images. My painting skills leave a lot to be desired, but that is just another learning curve I need to overcome.

Here is a video of the design, build and demo ....

    I was worried about the tiny servo, but it works surprisingly well. Fortunately the head is quite well balanced, and the accuracy of the 3D printer helps a lot. The original DC gearmotor I bought for the…

    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)

    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.
