Day 1
(4th August 2015)

So after throwing around a few ideas for a new project to sink my teeth in to, I decided to go ahead and do my own version of an Astromech Droid, rather an Astromech "Smartdroid". With K-9 being one of my all time favourite on-screen robots, R2-D2 was (and still is) just as much of an all time favourite of mine so building one of my own droids is a logical step for me. As my other robot showcases where posted when the majority of the work was done, this will be a build diary of sorts, with updates throughout the build.

So wanting to get back to building, I had a few ideas floating around for my next BIG project and the thought about doing an R2 style robot came up a few times in the past (the blueprints I drew up that I've posted are 3 years old and was for an R/C version), and after encountering a few design issues for a large custom robot (which I will get back to one day), it was @Robot56's fantastic Astromech Droid project that was the final push for me to decide what direction I should go. There are so many great scale replica Astromech builds around that people have done, but much like my K-9 2.0 build, I want to stay away from doing an exact prop replica build and do a custom build with custom paint job (as seen in the blueprints) while still keeping with the overall original design.

So what's with the name E4-B4 (Eiifor-Befour)? Well its kinda based on the EZ-B 4, of which this little'ish guy will have two of them. One master v4 to control motor controllers, ping sensors, v4 soundboard, camera and sensors, while the 2nd slave v4 will be used for all of the servos used as well as additional sensors. E4 will be mainly built using MDF with a plastic covering, and movement will be powered by 12v 30 watt gearbox/motors for the drive system. The "burtt acoustic signaller" and system ventilation vents on R2-D2's chest area (the two silver square'ish panels) will be replaced on E4 with a tablet PC, and the Optical Holographic Projector in R2's head will be something similar to what E4 will have, using a portable projector like the Aiptek or the Pico Genie, so no holograms... yet.:P

The dimensions will be slightly smaller than the original prob, but not by much so E4 will be plenty big enough. I'm intending to fit a few useful tools that he will be able to deploy, and of course have the fully rotating head which will have all kinds of bells and whistles. I have some of the MDF sheets and 2x4 wood lengths for the frame already, and the motors and head dome (lampshade) should be with me sometime this week, so it will be power tools at the ready. I'm in no rush to finish this project, but I am aiming to have E4-B4 pretty much finished by this December.

I will posting lots of photos and few videos throughout the build process, so I hope anyone reading will find this build dairy interesting and enjoyable. And as always, I'd love to hear your thoughts and suggestions (especially on the colour scheme). Anyway thanks for reading, and let the build begin...

Steve.

Missed out on grand prize to a BB-8, but really happy with the result. So E4-B4 has won me one of these...

Also great that he won as its another bit of notoriety for EZ-Robot.

So, a BIG, BIG thank you to everyone who supported and voted for E4-B4. It means a lot to have the support from you guys and I'm very grateful indeed (and so is E4).:D

Thanks Patrick. Looks like I've got a new toy to play with, lol.;)

you can store it on your atik for later use

Congrats and well deserved despite some really tough competition in that contest. There were some really cool devices, but I think your excellent instructions pushed you into the top 3 (it is "Instructables" , not "look at the cool thing I built").

Cheers Alan.

Absolutely right. There really were some great entries (I did like the wood millennium falcon, although I wanted that prize, lol), so E4 did well to get placed where he did. Like you say, it's not a wow factor contest, it's about the content so I must have gotten something right.;)

Thanks again.

Thanks David. I am well chuffed with the result.

sure to audit this statement.Check whether you need long haul care protection. In spite the fact that no one likes to consider being with a noteworthy disease that can wipe out all investment funds, this is a believability as you age. So evaluate your requirement for long spell of care protection.

Cheers Ron. Thanks very much.

@DJ. If you're reading this, any chance you could get rid of that spam crap posted in post #196? Thanks.

Hey Steve, maybe down the road you can use the orbit headset and use mind control to operate E4. The only concern with that is, he may send feedback and control you....

Be Well,

Lol, that's a thought (no pun intended). I was actually thinking what I could use it for in regards to EZ-robot. I'll have to see if a can come up with anything.
#199  
I think it's an open source code, so E4 may be able to read your mind....

That's a scary thought... for E4 I mean. I couldn't put the little droid through that.:P
