Hello All!
Omnibot #1 arrived today.
I'm still waiting on Omnibot #2 to arrive. Soon hopefully.
Going with a Black / White Spy vs Spy theme.
The wife and I decided on their personalities. The "evil" black Omnibot will have Mr. T audio clips and the white "good" Omnibot will have Pee Wee Herman Audio.
Here are some quick pics. The electronics were DOA. Thankfully the drive motors are all good.I want to preserve the original look of the front so I gutted everything. Clipped off the front of the PCB to preserve the switches. This Omnibot will be wet sanded and painted white.
I'll be adding a few things along the way. Fricken laser beams too!

Next to his decapitated pal R2.
About 5 minutes later. 
PCB chopped!
Stare into his eyes!

Anyone run their Omnibot motors at 12V?
Spent some time tonight carving out the head pieces to get them ready to mount to a servo.
I was worried on how to do this and make it look good. I ended up running a sharp knife along the edge repeatedly. I came out nice and a little sanding it looks perfect.
Also shopping for H bridges and batteries.
Wondering is a 7.4V 2200mAH Lipo would be good enough to run the EZ-B, MP3 Module/Amp and Omnibot motors?
The original batteries were 6V 4.5Ah. Thoughts anyone?
I have ran the omni motors at 12v for testing . Are they going to be autonomous ? I wouldnt go with a batt that small 2.2 amp hr , get something bigger than the ub645 , on eBay its super easy to find lithium batteries , for example the 12v 9.8 ah , you could fit one in the same space as the ub645 battery they usually use , as long as you are using standard servos ezb can provide power to them and stock motors seem to run fine on 12v , they will for sure have the torque they need to tread over carpet using 12v
Finally got some time in the garage.
I've been working on the dome plate. It is friction fit into the Omnibot body. It fits perfect where the front/rear tabs used to be that were removed from the head body.
The plan is to mount the servo directly below the plate for head rotation. Also toying with the idea of hanging the Sonar from it as well. Just thinking about how to link the Sonar to scan via a servo. Some proof of concept photos.
Also drilled the holes for the power switches.
Still waiting on the MP3 Modules / Amps to arrive.
Ordered (6) 2.5A Motor drivers tonight. (2) for this project, the rest for some other future projects.
Dome revision ver. 3.0 finally worked. I was having clearance issues with the head vs. dome. So I chopped down the head base to follow the inner contours. It looks great and works.
Did up my eye LED's tonight. One will stay with red and the other will be purple (White LED's).
Here is a quick vid. They are hooked up to my C6C setup (Wireless 6 Channel PS2). The Omnibot on the left has some sort of interference/issue going on. Hopefully that will go away when connected to the EZ-B.
I'll have to get my cameras ordered soon. I won't drill them in until I have them in hand.
Next up will be mounting the Sonars and servos for arms.
Things are slowly progressing along. Waiting on parts sucks.
Mounted my sonars. I went fixed position for now.
Received my MP3 modules and little 3W amps arrived for the Omnibots.
Worked on wiring them up and all was well... for a little bit. :-( One of the MP3 modules just crapped the bed on me. I've sent a note off to the E-Bay seller. We'll see what he says. I need to order (3) more of them anyways.
Still waiting on my motor controllers. Working on a new idea for making the Omnibot arms move with high torque servos and shaft adapters.
After that I'll get my batteries ordered then it's off for final paint and some dome polishing.
Anyways, on to the pictures! Everybody loves picture right?
MP3 module mounted and wired. 3W amp mounted to the left.
A further back view. You can see the nuts for the EZ-B mounting posts.
Mounting posts in place for the EZ-B. Only drawback is it won't fit the DC barrel jack that comes with the kit. Ordered some 90 degree plugs from the bay.
MP3 module mounted. View from the front. Lots of room to spare.
Sonar mounted. Going fixed position for now. Still need to drill holes in the plastic front plate for it.
Head mounted on head plate I made. Head is attached to servo mount. Front lip locks it into Omnibot body.
Servo mounted from below. Solid and a rock!
Another view of the servo mounted.
That's all I got for today. When both MP3 modules were working it was hilarious!
MrT - "Enough jibber jabber fool!"
PeeWee - "I know you are but what am I?"
Once I get the module replaced I'll fire up a video.
All very neat and tidy there Lumpy , Good work. I cant wait to see the video .

I can't see any pictures on Lumpy's post and a few other threads on the forum. All I see is a little box that says click for actual size.
Anyone else have this problem?
