I loved the idea about modding my own omnibot so i found one on ebay and bought it
My initial plan is pretty basic, just put in some servo's for the head and arms, i have an H-bridge for the movement and put in a camera.
I bought it for about $51 and $64 shipping, but I ended up paying an extra $45 on import duties (which I think is ridiculous because it's not even sold anymore) I just got the box with my omnibot (it was shipped inside a burger king box ):
Look at all those stamps!
thank you!
Here comes the head
What a beautiful baby..
Fortunately, he wasn't that discoloured from the sun so I just washed him and didn't have to repaint.
Here's the entire collection of video's. Please excuse my poor English, I wasn't doing bilingual education back when I shot these:
I'm currently working on renovating him. He was very poorly glued together and his arms snapped off. I'm planning to release a final video before my visit to EZ-Robot in July.
Other robots from Synthiam community
Bhouston's Inmoov's Sensors
Radmeck's Big WALL-E
Mounting on or by the door may be ideal for you , easy access with one screw so your not taking the whole bot apart all the time.
I'm thinking of putting a netbook on the front panel that will control the EZ-B.
I've now fully taken him apart and cleaned him, now i'm waiting for parts to put inside
Excited to see your progress. The videos are a great idea. Very friendly and informative. Keep'm coming!
PS, how old are you? I think you might be one of the youngest robot builders i've ever met!
I'm 13 years old (14 next month) so i'm hoping to finish my omnibot so he can serve drinks at my birthday
I ordered some 20kg/cm servo's for in the arms.
As for my workspace,
It was really messy before so i decided to buy lots of little drawers and i organized and labeled everything.
The screws were REALLY tight, took me almost 20 minutes for 6 screws *blush*
Great Vid Lyron! Good luck with your Omni Build!!!
Now i can also use a better quality camera since it doesn't have to be wireless anymore
I could also use a usb->ttl converter in stead of bluetooth
this site has some manuals on alot of robots,plus some schematics and lots of great info and links

I just looked on ebay but that's $200+ w/o RAM and hard drive while i only payed $100 for the eee pc second hand..
i got mine on ebay $125 and other one for $85 both had hard drives
one thing about the eee pc ,it draws about 3 times as much current much more heavy ,so will need a bigger battery and larger batteries to handle the load,i have asus netbook eee model and found all this out
$200 one you found might be new,since thats near the price of one
Could you please look one up on ebay for me then? I didn't already buy the eee pc so there might still be hope
here is a place that sells domes for any size on omnibot its 8 1/4 " with 1/4 " flange

i designed h-bridge design and pcb boards all info in zip file,made this design awhile back and sold many boards if anyone needs to buy the boards let me know,more that buy the boards the lower the cost to have it made ,boards are in 2 parts ,main reason is that the board is universal
logic circuit on one board and pwm h-bridge on another rated at 60 amp cont,but you can easy remove mosfets to save money,remove 4 of the 8 mosfets give you 30 amps
i dont get money from this and dont need it

Ultra Cool!!! I think I see a Budding D.J. the Second!
Should be a super little robot, when finished.
Lloyd
great job looks good
Thinking of a field in robotics?
I think we will see great things from you.

also forgot what is the make of the display,i heard something about sparkfun in video
just curious. It makes a really good video.
@MovieMaker What i'm using to film it is a Flip MinoHD to film it. I edit all of the video's on my main laptop, which has an i7, Geforce GT540M and SSD. I edit it using Cyberlink Powerdirector.
@robotmaker I recently got a mini-ITX for free from one of my dad's colleagues, but the specs are lower than the netbook i'm currently using.
The LCD is a SparkFun LCD with serial backpack. I've replaced the EZ-B's bluetooth module with a Sparkfun USB->Serial adapter. I order a lot of stuff from Sparkfun because shipping to the Netherlands is really cheap compared to radioshack, mouser, digikey etcetera.
thats about the same video setup i have only using a better board and the lastest I7 core ,board takes 2 I7 core processor,
and what windows software are you using
Then he commented that his video recording and editing setup is similar to yours, except his computer takes 2 of the latest I7 core processors.
just right having a hard time using the computer with my arm and elbow hurting from my fall i had
I don't know the specific brand of the mini-itx, think it's a VIA Epia from '06. Clock speed is i think only half a Gigahertz
The Netbook my robot has on its back is a asus eee pc 4g surf. It runs XP really well from its 4gb SSD chip.I've also modified it to have a touchscreen.
4" by 3" size up to 1.1 ghz plus under 12 watt of power
perfect for small robots
I think i'm just going to keep the EEE pc on him for now. I don't really have money for a mini ITX + LCD right now.
BUT really good job on your first robot design,i have a great neice age 10 thats trying to learn and help me
keep up the good work.
@Robotmaker, I am still looking for a min itx board for my Leaf project. Can you let me know also if you find a good deal on one.
Thanks
what size board will fit inside your robot 7" by 7" or pico size 3 1/2 by 4
for leaf you need about 2 ghz
1.1ghz may work,i have one but havent tested it yet and are you using the animated face,that uses a lot of memory resources and speed,plus need to use windows xp pro
robotmaker thanks for any help you can give me.

Here is a video of him bringing money to the barrel organ:
Thank you
I started young at electronics and became real good
Also a degree in robotics is a good course to go
i wasoffer a job at a robotics company ,but too far away in (california) so might be another idea
to see if your colleges in your area has that type of course
For the last year, he's been standing in a clauset with a broken shoulder. I couldn't figure out any good mounting options so I had glued it on and well, it broke. Any good mounting tips?
As soon as I finish high school, I'm planning to go to a technical university. I'm thinking about one in Delft or Eindhoven but I could also go study in a foreign country.

Any help would be really appreciated
You did an awesome job on that robot! It's a shame to see it out of commission. I am kind of bumbling along trying to program my robot. I wish I had your talent, but the fabrication and building part is what I am good at. I would like to offer a suggestion.
Hot glue is great for a lot of things, but it is not strong enough for what you are trying to do there. I would pull the metal washers off and scrape out all of the hot glue. Then get yourself some nylon washers the same diameter of the part that you are trying to extend, and glue them on one at a time with "Super Glue" or something like that.
Epoxy resins are good for that sort of thing too. Just don't glue your fingers to it.
Just another thought.
You could wrap a piece of cardboard (or even a playing card) around the piece that you cut too short, having it stick out to the length that you need. Stick a rubber band around it and fill the extra space with epoxy. Peel the card out when it dries.
There is always a way to fix things if you put your mind to it.
Wonderful job on the robot. That was how I was with computers back in 1964, a long time ago in another ...
Keep up the great work, learn all you can from DJ and others.
As I tell my kids, look at something from a 10,000 foot view, step back.
Danger! read your post of the 17th, thanks for the info.
DJ maybe we could have a new post area called tips and hints plus Rich's post too.

I was wondering how you attach your Asus. Is it with Velcro?
Yes, I used the ultra-strong velcro that can hold up to 10kg.
