Hey All!

Finally got some time out in the garage. Sorry that thing called
"Life" got in the way! ;-)

Some pics. (Sorry I didn't have my fancy camera with me)

Hasbro R2 in bits and pieces

A close-up of my dome posts. This is how it is on my full size R2.
Simply friction fits down on the (4) screw posts.

L298 Motor Controller. Seemed like a perfect fit to mount on R2's
center foot.

Another view of R2 gutted.

Back half of R2's body. I utilized the existing mounting posts
and added a styrene plate for mounting stuff.


User-inserted image


A good view of the rear half of R2. I did some extensive dremeling
and removed the whole battery compartment.

Here we have everything fitted back together. EZ-B board mounted.


User-inserted image


Gutted dome. Note the black tipped posts. Those match my screws
for the friction fit.

Little buddy all back together.

Heart beat...

Another view of his almost complete internals.

12V Lipo 1500mAH battery I've been experimenting with. Fit's in R2
and Wall-E easily. Doesn't seem to run the EZ-B very hot at all.

Things left to do to R2:

- Add Scorpion Mini speed control for dome rotation
- Add serial MP3 card w/amp
- Add Camera to dome eye
- Add slip-ring to dome
- Locate and mount Sonar

Hope these pics help other builders with ideas.

Cheers!

so what I decided to do based on you pro android builders...is to make a frame within the r2

this way I can crack the case open and work on the lego technic frame I build inside of him to hold servos, and some drive train gears...

Slip ring is in!

Don't think his head motor was meant to run on 7.4V. It's just a blur spinning 360.:D

I'll post a pic and vid tonight when I get home from work.

If all works out ok with the hotpot potentiometer going into big R2, I'll add the
same to little R2 for dome centering.

As promised.

Pic of the slip ring installed. The center plastic "cap" is the plastic part
of a pill bottle safety cap. Friction fits perfectly. Drilled and hot glued
the slip ring to it. Wires are wrapped with solder to give them some
firmness.

I'm going to grease it up a little to cut the noise.

All I need is a camera and he's done.

Very cool! I am def inspired to build an R2 ...not to mention a B9....etc etc after my talking head is complete...:)
#24  
Dude that spinning head is awesome! Now it needs freagin lasers!

Now you need to buy a stun gun so it can zap stuff. Or make something that looks like it.

Josh,

You got me thinking.

Although a active stun gun would be great, I'm sure my son would abuse that feature. :D

It did bring up a thought about a recent project I saw. Do you know what a Jacob's Ladder is?

The old mad scientist *Zip.Zip* electrical arch? I saw a recent re-invent of that with EL wire.

Thinking I could make a minature zapper probe with blue EL to simulate an arch.

I'll see what I can Do.

Jacobs ladder was a fun build i made for a science fair project for school,that brings back memories.
Same as a real volcano that erupts in grade 5,i was a science master in school all straight A'S.

@robotmaker..I hope your enjoying your retirement! ....@lumpy As your robot is an R2 unit it would also benefit with a "projection display" I recently picked up an old 500 watt slide projecter for 5$ at a Lions sale and will be incorporating a lcd backlit with mirror to project onto anything! ...Perhaps one of your windows. Something as simple as this
Projector
Of course I would not use the 500 watt lamp provided

Thanks @irobot58,i did so many many changes and updates to my projects.
And i bought a lot more robots 93 now.

For the Hasbro R2 I'm thinking something less advanced.

Like one of my kids toys, I want to print a Leia picture onto a
transparent sheet, then simply shine a superbright LED behind it.

Simple but effective for what I want out of this little guy.

Now the Big R2 on the other hand needs a pico projector of some sort.

Other builders are currently experimenting with projecting full moving
vid onto a fog/mist stream or clear mylar.

It's effect is quite stunning.

It's on the list of upgrades.

#32  
I had a funny thought...as the R2 unit is steaming the rug it can send out misting vid!:)
#33  
I bought a small pico projector for my hasbro R2-D2,it will fit just right in the head
#34  
Also LUMPY have fun at DJ'S party today

Hello,

on the last video with the slip ring...im a lot confused.
the dome spins but the top wire coming from the center do not....
so if that wire connects to a servo or led that is attached to the dome...would the wire not tangle?

I think im not understanding a huge part of the slip ring

I want to avoid putting a mini ezb in the dome and a og ezb in the body.

Hi Hoolagen1,

The wire will spin as well.

Crank the volume! :D (Same slip ring I used in little R2)

Love it!

I'm such a nerd. Missed this same video on the previous page.

D'oh!
