This project has evolved some , the basic rundown is I'm modding two Omnibots , one a regular the other a larger 2000 model. I will have two ezb kits , rad base idea was thrown out because of so much noise but could go back on the table if the omnibot drivetrain is too weak to pull it.

Sulla's R2d2 Bb-8 Mashup Robot Project
Thought you guys might find the project I am working on interesting. Its an R2D2 BB-8 mashup robot. So far coming along...
too bad you live to far away i would be able to help you unless you move to fla ,since i have a room for rent,mostly goes fairly quick,other renter moving out in less then a month
That is probably because it is a Beach House and their vacation comes to an end, I would guess.
@JOSH found some info about your sensor on the roomba tech forum,it seems not to much info about it only that is ultrasonic transducer,now i know it uses a piezo sensor one for transmitt and one to receive,at work with sell a design close to it for detecting bubbles in a slight glass tube use in A/C field so the only thing i can do since i know how the design works a little, is reverse engineering it using my digital scope and i guess other equpment i might need and design a circuit for it its FUN for me since i love working with sensors mostly likely will post my design and results on the roomba forum too
there is a easy way to use it,but thinking you dont want to use it is using the roomba board ROOMBA board would slove many problem,navigation,docking and autocharging,and h-bridge circuit all on one board controlled by EZB
@mel i would never live near the beach,mostly because of salt water corrosion and then storms comming in to damage your house near the lake YES ,getting ready to look and buy one near a lake
Ok looking at mounting options I borrowed a couple frames from glickclicks video. I may try both ways and everyone can make suggestions
This is just examples , I'm going to cut down the shoulder mounts and do test fits. The brackets I'm.using are lynxmotion brackets.@ROBOTMAKER BRETT is sending a roomba board with some kind of modders guide , I tore up a ps2 mouse for a plug today. Also I'm.getting a 6v battery specifically to run the servos and ezb from Brett , so if.the roombas hbridge.is strong enough to run the omnibot motors at 12v I will do that .
Sorry about the quality. I wanted the vid to fit in an email. The arm is just stuck on with double sided tape to show Josh my idea. I didnt want to mount it just yet. Im going to put ABS on the inside to strengthen it first. After that the bracket will go here the hole is. After I actually tested it with the bracket that came in yesterday I REALLY liked the motion! It looks like he could touch his face and scratch the back of his head.
I didnt post it yet because I was waiting to have a permanently mounted first.
As I was telling Josh, my bot will just be gesturing and not truly lifting. So I suggested trying both ways to see which way handles the stress better.
It looks good. I would like to know how it works out.

After looking at this I may put the servo mount there. Only if I get much stronger servos! Each inch counts and I want it to support his own arm for goodness sake. LOL
Hahahaha... yes. That is important. (It took a long time to make minions hands, I was having a blonde moment and did not even think about if he servos could lift it.) They fell right down.
