Just Another Omnibot

This is my Omnibot Tomy. I haven't really been able to work on him much, but I've been collecting a lot of parts. I have the camera working now, even though it isnt mounted yet. The radar and corresponding servo is working well. Still waiting for Dj's motor controller to come back in stock to get him moving around. He's definitely a work in progress that I'm taking my time with. Im going to leave him yellow. I was going to paint him but the faded and dyed plastic actually kind of grew on me.

PS he has the other arm.. its just in pieces at the moment...

I resolved the camera problem that I was having earlier. Now however, I'm having trouble getting the ezb to connect to the computer. If I open a new project it connects just fine but then eventually has the same problem. I cant seem to get the ezb to connect while in my projects folder. Do you think its a problem with my blue-tooth or how i am formatting things? Any suggestions would be great.

Thanks
Aaron

thank you!
it has been a long time since i have made any modifications to my omnibot. However, we just put in wood floors and my parents are already complaining about cleaning the floors so i am considering turning him into a roomba like robot (what a perfect excuse to spend money on my robot;) ). I was looking at jstarne1's squeegee project for inspiration but mine would be less dedicated to being a roomba. i plan to allow mine to be a plain omnibot with cleaner and sprayer attached to the body

I was wondering about your base. On the Omnibot2K , it has two extra wheels. Yours seem to have a swivel and castor. Or did you put that on there? I would like to see more.

my omnibot has only 4 wheels and a single caster in the front. I think they added the extra wheels on the 2000 because the robot was taller and heavier. the caster isn't the most ideal design in that when the robot stops it leans forward on the the caster and then rocks back down to the rear wheels

Hi I have the same Omnibot model you have and I put some lead in the back to weigh it down and that stops the rocking motion. I got very frustrated with the noise of the motor drive and gears so I ordered some small metal geared motors and mounted these inside the drive box and threw away all of the plastic gears. They were virtually silent in operation but too slow as I got 40 rpm motors and really needed double that speed if not 100 rpm. So I'll get some others and try them but ideally the whole drive mechanism wants replacing as the front caster wheel is effective but primitive and on mine has a tendency to squeak as there are no bearings to speak of

Great job on yours :)

Wow i didn't think of adding ballast weight to the back... the lead is a really really good idea!

do you by chance have a link to the gears and motors that you used? I would be really interested in quieting down the drivetrain

The motors were sourced through Amazon Uk site the ones I used were 6 volt 40 rpm not really fast enough and need slightly more torque. The supplier in china is Hossen and you can get them on Amazon in the US. Or Solarbotics supply similar products just not tried them. Just needs a solution to either connect them directly to Omnibots wheels or via a gear mechanism. They are blissfully quiet though if I get sometime tomorrow I'll post a quick video of my Omnibot where I just glue gunned the motors into the drive box and connected them via the one gear to both wheels

Updated with short video tracking to a red ball (must remember to video in landscape mode on my Iphone) The clicking is the servo driving Omnibots head

my first official print for my omnibot! I replaced the tape player with a panel that holds the sweeping and cliff IR sensors. getting rid of the tape player creates way more room inside of the body

I have no idea why the pictures are being formatted sideways? *stress*

Cool front plate! I laser-cut one with a voltmeter and ammeter.
By the way, there is no such thing as 'just another omnibot'. They're all unique:D

For rotating, you can view the file in windows explorer, right click on it and choose 'rotate left/right'.

Thank you Niek! How is the rebuild to your omnibot coming along? Have you made any changes since updating your thread?

I made the title a long time ago when it seemed like everyone was working on an omnibot... But yes I agree that no two ez-powered omnibots are the same

I've been busy rewiring him to make it a bit neater. I've also glued in my front plate and replaced the battery:)

My front panel lights finally came in! I have to print an upper plate that houses all of the lights but Im so glad this thing is prewired and will only use one digital port!

I got the upper panel printed out last night. I just need to add the the tinted plate for the front of the led's and the paint in the TOMY lettering :D

I will post a video of the lights when everything is all painted and mounted properly

Mounted the V3 board in the body today. decided to stick with the V3 because its what I intended to put in my project from the beginning and my next project will need both of the V4's i ordered:D

Also got half of the front paneling wires organized!
