When I say "movie robot" what's the first thing that comes to mind? If you're like most people, you are probably thinking "R2D2!" R2 has become something of a cultural icon, and I was looking for a new hobby. After exploring the EZ-Robot site and tackling my first project, an almost-complete Wall-E. I decided it was time to dive in. After working my way through some of the advanced features that EZ-Robot offers, I began. It seems every day I learn another feature or function from the site, and it has served me well as I've progressed beyond Wall-E. Armed with this new knowledge, I decide to attempt my biggest project yet: a variation of the R2D2 droid, called R7-M1.
A Syren 10 motor controller, powered by a 12 volt battery, is used to provide movement to the dome/head. Another two 12 volt batteries are powering two scooter motors, which are controlled by a Sabertooth 2x25 motor controller.
The Ez-B controller is managing the control functions of the MP3 trigger, wireless joystick, Syren10, and Sabertooth2x25 , and also features a personality generator, voice recognition system, random sound and movement, and camera eye tracking.
I'm looking forward to adding even more functions using sensors and other devices. Stay tuned for more to come!

@GotRobbed,
I really really like the motor beltdrive wheel system you have going there. Are the spherical casters on the legs there for weight distribution or because it looks uber cool or both?
Thanks
Kevin
Hello all, thanks you for the kind responses on my progress, It is soooo exciting when you see your project up and working from the time you first laid it down on paper to the time you see it move for the first time. To answer some questions: For mounting the motors to the feet, I used this design which I found on yahoo
scooter motor foot , Materials used: Wheels from here but I had to cut some of the hub off because it was a bit too wide
The front wheel caster are from http://www.rockler.com/product.cfm?page=21969 and the rear casters are from http://www.rockler.com/product.cfm?page=21974&site=ROCKLER ( the reason I used it for the rear is just in case the droid does a wheelie when it moves) Belt: http://electricscooterparts.com/drivebelts.html Belt Size: 405-3M-12 screws: 1-1/2 inch #8 32 thread machine screw and 2" Threaded Aluminum Post and the screws that came with the motor.The dome ring I used a Lazy Suzan and an A&A gear set which I did get from another builder. Mounted both with 1/4-20 screws The motor I used are from http://www.skycraftsurplus.com/pittman6to24vdcgearheadmotor.aspx. Put all together it looks like this:
.As for the weight of it now, its probably about close to 40lbs now. when fully finished, Im guessing about 75lbs.
I need to start working on the Dome(head) soon and also start looking for paint. Doing the little extra detail parts are going to be pain but worth itin the long run.
But I am having trouble with the MP3 trigger, I need some help if anyone could provide please. I have speakers hooked up to an amp
amplifier which is hooked up to the MP3 Trigger
then to the Ez-B controller. The problem is that when I insert the 1/8 jack into the input jack of the Mp3 Trigger, I get static noise. How can I get rid of the noise? Im hoping it not the input of the MP3 trigger cause that would mean I need to buy a new one. Any suggestions?Thanks more to come soon
@Gotrobbed
Check output from Mp3 Trigger with headphones ,that will tell if card is ok
Please read notes on connecting amp to output of mp3 Triggerr http://www.sparkfun.com/datasheets/Widgets/MP3Trigger/vs10XXan_output.pdf
You may have a grounding issue between both cards.As gnd on Mp3 is at 1.25 volt
hey Bravia, I tryed messing around with the connection. connecting and reconnecting, soldering and resoldering but nothing seems to work. As soon as I insert that 1/8 jack into the MP3 trigger, its like I get feedback and staic right away. I may think it could be a volume issue with the Mp3 trigger and the 2x25W @ 4 Ohm TPA3123 Class-D Audio Amplifier Board. I think the default settings on both are set high and I really dnt know how to lower them.
Hello,
I know lots of us picked these up to solve our sound woes with the J.E.D.I controller setups, VMusic2 and amplifiers.
Search E-Bay for :
Pac SNI-1 RCA Ground Loop Filter Isolator
Solved my issues with amps and humming/static noises.

You may also need a filter capacitor to ground.

Great news.... I solved my MP3 Trigger issue.... it turns out, it was a bad Audio Jack.
http://www.sparkfun.com/products/8032So, I replaced it and yahooo!!, everything is working great!!
So now that was solved, I started working on the Dome Part(the head) of my droid here is a picture of what I have done so far... but ... more to come....
here is the eye
I cant wait to see the next update!
