So I am finally to a point to report some progress on my omnibot hack. I call him BOB. I decided to change his color as there are so many white ones out there. I used a flat black with silver accents.

I will be getting the motor controller up and running this week, then hook up my joystick and hopefully get a cool video this weekend.
Nice , I did find out your motors are mabuchi 6v
Testing out the drive section:

And here is BOB all buttoned up and ready to go:

Next is setting up the joystick gamepad control. After I get that figured out and working right then I will post a video of BOB chasing around my dog Peanut. This should be BOB's debut....

Thank you all on this site for your help and encouragement. But even as I finish BOB I am already working on my next bot.

hahahaha they're all sideways. Darn cameraphone
Your not using.the BV motor controller?
I'm using that on my next bot - a 2 foot version of robot b9 from lost in space. Bob has always just been a test bed so I could get ideas and work with stuff. My Robot B9 is the one I want to put a lot of work into and the best parts (like that motor controller). After reading another post I decided to try that stepper motor controller I had and it worked (it takes up 5 ports!). But I wasn't planning on adding any more to Bob so I didn't need those ports (no MP3, or sensors other than ping). The B9 that I am starting next will use a lot of ports because of all I want to do to him. I am going to use my RAD drive section on him and the controller you sold me to control it.

By the way, is that fan enough to cool that controller or should I get some kind of heat sink as well? I also noticed that DJ has taken ALL motor controllers off his website.
Okay, here is Bob's debut: I am using joystick control in this video and just playing with different things. His motion tracking is really cool and he seems to be checking out his environment. Mods: Camera, head, radar, chest lights, EL wire accents, right arm movement at shoulder, left arm movement at shoulder, elbow, wrist, and claw. So without further adieu...BOB, Bret's OmniBot!!!

B.O.B. looks great, Bret! *cool* You are truly an inspiration to all of us builders. Kudos to you on your Omnibot build. Can't wait to see the next one.

In the video, was B.O.B. attempting to dance "the robot" at one point? I noticed his claw-arm in a valiant attempt of it at one point. Also, I couldn't help but notice the lack of dog chasing... ;)

Again, great to see how far B.O.B. has come!
Awesome man. Are you gonna make him autonomously controlled?
Eventually, I will play with code and let him roam freely. For now I am having fun with the remote control on the gamepad.
Can I use a ps3 controller for this kind of thing?
I believe you can - I just got a $10 generic off ebay with dual joysticks on it - usb. It works great so far.
Oh ok so your using a ps3 type Bluetooth controller , that's great.
@ jstarne1,

I think I saw a post on this a while ago...the thread discussed hooking up a PS3 controller wired with 3rd party drivers. Just found a thread describing how to do it BT as well..... Looked pretty cumbersome....I actually think buying a wireless one off ebay might be easier;) Let me know if you find an easy PS3 controller solution......but $10 is not too bad to have a dedicated ROBOT wireless controller.


Wireless would definitely have been nice, but money talks. The USB connection to the laptop isn't bad. I had a lot of fun playing with him last night -
Easy way to get Bob to talk is add a wireless bluetooth speaker to him.
Then any PC sound comes out of BOB.
If you turn off the wireless speaker then sound comes from your regular speakers again.
Would work for B9 also.
I just paid for a 24 inch B9 from ebay.
Hope to get it soon and start modding him.
I have 2 old RAD robots, but I may use something else to drive him.
I need to finish my humanoid first.
@mcsdaver - thanks, that's a good idea. I actually bought an mp3 trigger set up for B9 and I will use it's auxillary outputs to drive the voice box lights of the B9. But the bluetooth speaker is a good idea for BOB. If you look at my thread for my B9 I used a RAD 1.0 track base for the drive section and it really zips around with a 12V battery in him. Plus I use a servo to change the gear selector for high or low gear. Do you have any progress/pics of your humanoid project? I would like to see that. I think my next hack is going to be K-9 from Dr. Who. I have a 12" RC one that does not work so is a prime candidate for EZ-B.
I am trying to build my humanoids head before showing him off.
He has a Robosapien V2 upper body with my robotic arms I had on my C3PO.
I may get back to C3PO sometime, but I want to get this robot from a story I am writing built first.
The arms have 7 servos each and the head will have 2 servos and the camera.
I am rebuilding the legs from the Robosapien to see if I can make it walk more human like and be a bit taller. I wanted to use the hands too, but they are too big for my robot.
The V2 hands have fingers as long as mine.
I have been following your Bob build and your B9. You are doing great on both robots.
I have 2 RAD robots to use for parts, but I may use something else for B9.
If I could find a good head for him I would build a much bigger B9. I have two 1/6 scale tanks.
One is in perfect shape, the other wont drive reverse anymore. Could rebuild it into a much larger B9 or a Johnny 5 robot. It couldn't handle a full scale B9. I do have wheelchair motors for large robot fun.
so, he is also sort of a Franken-Bot. Can't wait to see him.

@ MovieMaker
Yes, a franken-bot of sorts. I started a thread for mine so I wont take over Bob's build.
Pics soon.
