I have taken a couple of years off of this omnibot 2000 build. I kind of get stuck, frustrated and quit. Then every no and then I comeback and look at it again. I have watched a lot of the videos people/bot have recommended and I'm still stuck. Mostly this is because I'm not an electrical engineer...LOL I know how to take things apart and monkey with stuff. I can solder and follow instructions but this project has stalled. My main issue is that the videos go to fast and are not detailed enough for my limited knowledge. So here is where I'm at. How do I wire the hbridge to the ezb and battery and how do I wire the 8 motor wires to the hbridge? Here are a couple pictures to show what I have going. Thanks in advance for any advice.

I used https://www.ebay.com/itm/Servo-Bracket-2-DOF-Short-Pan-Tilt-Sensor-Camera-Mount-Kit-Camera-Gimbal-MG996/152696892625?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649. 2 servos for up/down and left/right. Mounted the bracket on a piece of cardboard with a lot of hot glue. This is just a place holder til I i finish the 3d model for something more solid. I cut away part of the neck to try to keep it stock looking and still use the original hose. The top of the pan/tilt bracket is glued to the bottom of the head. I left enough of a gap to run the servo leads from the eyes down to the EZB
Thanks Xuven,
I just got the idea to use one of my Disc Golf mini markers to make a frame for the servo. What I was getting at is which way do I mount it? Sideways or front to back? Or does it matter? The ultrasonic servo I can set the radius that it can turn. I'm not sure if that applies to the motion tracking so I want to get it right before I break out the hot glue. =)
Front to back?
Sideways?
Sorry in advance for the poor images but it was hard to get a good picture. In the collar I have 2 layers of cardboard glued together. In the middle is a cutout for one of the servos to sit in. The other servo sits sideways on top in the bracket linked above. It's really close to the opening in the collar and the top of the bracket is glued to the bottom of the head piece.
Here's where I got the idea from. Hopefully this can better show you what I mean.

Perfect. Thank You!
That is pretty sweet! You convinced me to do the same thing. I got the 2 servo mounts on amazon for 14 bucks this morning. Do you have any other pics of the neck/ bottom of the head? I looked at the project pics on your profile and the video link you posted. That is giving me ideas on how to do it. Thanks again, my friend!

I had the same issue of finding pictures. I told myself I would take some and document along the way...never happened lol. If you can post a picture of the bottom and top of the collar. I should be able to use paint and draw something up to help you get started
