Yesterday I was able to borrow an iPod touch and verified that it was able to control servos (or R2D2) as well so that theory is confirmed. I was able to use a iPhone and the iPod touch at the same time and it worked just fine. Also I was able to remove a computer from the setup. In the video below, a computer was acting as a OSC message translator. The message path would be something like this:
iPhone –> wifi router –> computer –> wifi router –> microcontroller –> servo (or motor)
The iphone would send a message like
the computer would translate that message into this and send it to the microcontroller
Simple but effective.
Recently I was able to do the same without the computer and have the microcontroller do some internal translation of the message.
Now the message path looks like this:
iPhone –> wifi router –> microcontroller –> servo (or motor)
Yes the R2D2 will have a wireless router inside it and will be power from battery.
I am also working on controlling a vmusic2 module in order to produce the sounds R2D2 makes. I am also planning on controlling other parts of R2 with this setup as well including:
- Dome motor
- Feet motors
- Holo servo
- door panel servos
- JEDI system control (lights)
- Periscope (eventually)
- Lifeform scanner (eventually)
- and more
Another nice aspect of this setup is that I can add microcontrollers and remotes (iPhones or iPod touch) to extend the system.

I found a way to remote control my R2D2 with an iPhone. I’ve got minimal control working now. Once I perfect it, I will share more details, but for now this will whet your appetite. In the videos I demonstrate controlling a servo and the dome motor using an iPhone using the accelerometer (tilting the iPhone controls it) and using a slider control on the touch screen. Other touch screen controls are possible too such as rotary controls, buttons, XY controls, and multitouch as well as gestures. I should be able to interface with my J.E.D.I display as well and type in text messages in the iPhone that will scroll across the front or rear logic displays.
(Cue evil mad scientist laughter ) Muh ha ha ha ha!!

I got my legs attached to the frame and the dome as well. It’s really starting to look like R2D2 now and not just a pile of parts. Next step, attach the skins to the frame.

I picked up my COM-8 frame on Friday and was able to put it together Saturday. I actually made some of the pieces myself including all the spacer rods and the shoulder rings (not pictured).

We had a birthday for my son over the weekend and I asked him what kind of cake he wanted. Guess what kind he asked for?

Made some big progress on the dome. Just need to polish it and attach the dome panels.
Here are videos and pictures in its current state.

My wife went to a garage sale yesterday and found a cool R2D2 cake pan, so R2 will have a birthday cake for his birthday ;)

I just got my parts from David Shaw today which included the utility arms, front and rear logic surrounds, and totally cool holo projectors. Here are some pictures to get an idea. It was like Christmas today :D
I had to file one of the dome cutouts that was painted blue in order to get it to fit over the front logic display. I guess I could have painted it instead, but oh well.

Got one of the legs assembled yesterday and it turned out nice.
