robotmaker
i just got my omnibot 2000 from JOSH while back and got a chance to take him apart and start the modding 
first i am working on the base,i am adding tracks with floor inserts,so that he can move on tile floors and carpets.,these tracks are easy to use and add on and can move up to 60 lbs,will be posting photos ,parts lists in a few days
software using will be my AI SOFTWARE
my software
i guess will tell you the tracks i am using its from VEX ROBOTICS
vex robotic tracks
now if using a floor and carpet or rugs or both
vex robotic tracks upgrade
for up to 60 lb load need 4 motors if 30 lb 2 motors
vex robotic high torque motors
plus frame kit and few parts
whats great about this design if you dont want tracks add wheels very simple change
so you are looking at a universal wheel design
add-on latter are optical feedback
this design fits perfect without many changes to omnibot body
i have tried lynxmotion tracks,but lot of changes then need to make a track base
not universal and not great on floors,i have both track designs
thats what i am adding to mine ,10'' by 11'' frame fits perfect on the bottom and the tracks fit inside the large holes for the old omnibot wheels,with very little cutting and filing
i am using a 4 wheel drive system with each motor has a clutch
JUST about ready for PHOTOS
tanks make great bases for small robots ,hope to your's too
Thinking about getting one from VEX.
will post photos of it on the omnibot
also as you can see the green tracks has grooves in it for carpet or rugs
and the gray tracks has a flat surface for floors
will put up a parts lists of all the parts,with part #
Looks Great!
When you have time could you tell me what are the overall dimensions of this chassis? L x W x H
Thanks,
Rex
PARTS LIST
1-chassis 276-1033 need to cut it down some for 10 by 11 inches
4- 2 wire motors 276-2177 unless you only need 30 lb of load you need 2 of them
1-track threads kit 276-2168
1 track upgrade kit 276-2214 dont need it unless using it for floors too
1- bearing flat 276-1209 10 pack ,need 8 of them
2- clutch 276-1098 3 to a pack need 4
1-drive shaft 276-1049 cut to length for all motors
1-shaft collar 276-2010
1-bearing pop rivits 276-2215
will be adding fenders latter
also not mounted yet ,need a little trimming and filing
but it gives you more room in the base as you can see
tracks can be removed and vex wheels can be added very easy
almost forgot the ling to get the parts
vex robotics parts
Thanks,
Mel
P.S. forgot, your girlfriend gave it to you. But, you probably know how much it is worth.
Hey, what about putting a Omni2000 on top of a Roomba and just hook up the motors on the bottom and directly control them. That would probably work, don't you think? You would only need a saber-tooth controller or H-bridge. Good Work!!
Mel
my girlfriend did not give it too me,it was the BROOKSTONE ROVER robot i got from her
also how to hook up motors ,there are 2 ways for a 4 motor drive system ,one is hook up the left motors in parallel ,you need a 10 amp h-bridge
second is a lot harder and not needed indoors,but it takes 4 h-bridges 5 amps each
and 4 optical feedback encoders,mostly to for driving the front wheels slower then the back wheels ,to pull the robot out of a ditch ,used outside
working on this design for a much bigger robot design
latter on will add 2 encoders ,to tell distance traveled,speed ,if direction forward or backward and for navigation
You tried the Omni-bot on it and it did not look good. Well, it was a thought, I guess.
Mel
but i did buy another set of tracks for the roomba project to add to it
Hey Fred! did you hear the news about QBO. They have come up with a Qbo Pro EVO now. The kit price is 799 Euros and the EVO models are much higher. They are sold out of the regular QBOs at this time. I still have my order in. But, get this. They found out that in the regular QBO with the Hi-Tech servos, the servos made noise. It was not able to be heard by human ears. But, it messed with the microphones for the navigation. So, they did what most people do these days, they went to the AX-12 servos. Well, that increased the price because they had to modify the chassis to accept AX-12 servos. They added a thousand Euros to the price and included a Kinect type device. This was bad news for me, because I will have another robot running into things. :-( The Qbo, however , will be much better. But, you can buy a NAO for the same price. Too late for me, I have already given them a $700 non-refundable deposit. I hope that they have options to add the AX-12 for a very reasonable price, else, I am sunk.
They will be shipping yours in a couple of months.
What do you think about that?
We need some more pics. Looking good. I love those tracks.

my next step is drill a few holes,trim a little,file and sand
after that make a deck for my ITX board and leaf microcontrolller board
dont have a video camera
and specs are really good,i deal with specs at my work alot,
check to see why tanks and others use tracks,also very simple to see that tracks with grooves grab better then ones with out,same with flat tracks too,
hope you soon you will make more robots,then you will get a feel for designs
will be putting up more photos
i dont know if anyone seen the flimsy plastic on the omnibot,since it is a toy and not made for heavy loads
easy simple very strong fix is to use light weight aluminium angle on bottom or sides
i know JOSH like using fiberglass to make his stronger,but about the same weight,no mess,plus super easy to use aluminium plus cheaper is thin light weight angles (not flat) angle is a lot stronger
second easy to mount circuit boards,motors,servo's and lot more
will be posting photo's soon of my aluminium on my omnibot 2001 project ,and if needed can show photos of the weight it can handle without any sags,
some need proof instead of just concept can post photo's if needed
without trying it fisrt cant almost say it may not work
i took them off my vex robot i made for the outside,there worked great on roads and over rocks carrying a large load,when i asked the engineers at vex robotics about the upgrade before i bought them they said they work a lot better with them,i had 60 lbs testing and climb the rocks no problem
and same with flat surfaces
if you look at the lynxmotion tracks and compare to vex robotics tracks they are the same but no upgrade
so i think this will be a better idea on your omnibot project and a lot less work and time
and so much easy to make and add to your JARVIS
your wheels may or may not work on you carpet,but if going from wooden or tile floor to carpet might have a problem
and more to come
name i think for it will be the 6 MILLON DOLLAR OMNIBOT ,since will be named after the movie and might cost that much tooo
photo of the tracks mounted,also area around the tracks will be filled in
this is one of the photos of my aluminium angle,and attached to will be 2 decks
one to hold my itx computer and another to hold my boards,easy to make and mount very light and makes it easy to mount boards and other stuff,second to make it even lighter the angle aluminium frame with have rivets and pins,on top will have small sheet of plastic to mount my boards,hard drive,itx boards nd mybe power strip
will have more photos up of my design
the leaf board where i placed is perfect ,encoders ,h-bridge,most sensors,plus power
then on top cover placing mother board and EZB ,SSD and display and more
when i finish the aluminium frame,that does both hold the batteries in place and same time my LEAF microcontroller board,it has gyro and accel,plus can add a compass,all software and codes already made,will POST PHOTOS WHEN FRAME IS DONE
also better to have the mother board on top,more breathing space,less heat
going home from my work trip sunday,and at home my girlfriend got many boxes that came in for my robots
so on the RISER i am using polypropylene plastic,one reason lighter then most plastics,cheaper then any plastic ,easy to machine and very strong,to paint it use krylon fusion works very good
for glue use WELD-ON #1829 ,one of the 2 glue's that will bond it,another is heat,but very high heat
another is screws
will be posting photos and part #'s and where to buy it
also doing the same for my fenders around the track base
this week will have more photos of my design
I use the heat gun to heat up the ends to bend to the right shape. I then put it in between the slates on my coffee table to bend.
but also i am using a different type of plastic ,not acrylic
acrylic is very brittle it cracks to easy,even with fiberglass added to it
and the glue is WELD-ON #1829
i thought you did it that way
pretty easy to do,only where the bend is you take a dremel tool cut a small groove in the plastic at very little depth on the inside of the riser,it makes it very easy to form with heat,this is what the factory does,then you can still add a little bead of glue on the inside if you want for double strength
metal bender is the best for bending sheet metal and plastics
another small trick i got from work is to use parchment paper where the heat goes,so no heat marks are made on the plastic,doesnt happen with all plastics ,but it does work great and perfect every time,its also i use alot when baking too
blue screw in led light
will post my omnibot design as i get it done
2 large batteries will be in the center to keep it stable,second the track frame can be longer the frame parts you need to cut them down to size you want and same with the tracks you add or remove tracks to size you need,i found it holds up to 140 lbs ,35 lbs per motor ,times 4 motors
hope this monday to form the riser and work on the fenders too
if you look at the metal frame it has other holes to mount the track wheels ,and the idler wheeels you see i have 2 of you can remove them and still the belt will be tight
many ways to set the tracks,that one of the reasons i like it over LYNXMOTION tracks
only reason i have lynxmotion tracks is on my johnny five robot because the frame looks like johnny tracks
other reason is higher torque motors,encoders i am using are small pot type ,i think its optical design,but soon making a circuit that makes magnetic encoders have a digital output like optical encoders.it takes a few chips and havent seen any circuit on the web that can do it
made it so the mid section comes off easy ,where all the boards are and sevo's mounted to frame
without removing the bottom first
Looking forward to the rest of your progress reports.
the vexplorer you have is the frame i used on mine,motors take a standard H-BRIDGE or can convert to servo rc
my good news is going to fully retire,since i sold a big electronic patent design to a company and
will be working on my omnibot 2000 project and many more with EZB and some with AI software design
making it so ,its very easy to remove the panels for upgrades or repairs,like the way HEATHKIT HERO is made,plus bought 2 more robots ,one is sony AIBO that sells for $2500 AND OTHER KINDA LIKE HIM
will post photos in a few days
next is hands and elbow,design kinda close to the terminator,but using a plastic skin wrap around a aluminium body,each of the plastic panels will be easy to remove and all electronics and sensors will be attached to the aluminium frame
will post photos in a few days
bearings fit pefect in shoulder
here is photos of my arm design
mostly waiting on my belt sander to come in tuesday,rest of the 16 other machine tools comming in before christmas,my milling machine came in last friday
so hope to post photos before the weekend
so first thing tuesday morning will sand down my plastic peices and my aluminium angle for my body arm frame ,and use rivets and tap holes for some screws
should be able to post PHOTOS wednesday
the motors above are mounted to the frame
looking not to mount any sensors ,lcd or boards to the omnibot plastic shell ,instead mount to my aluminium frames,this way the covers come off super easy for quick repairs or adjustments
i did change it it use a little bigger gear,since they are ony the size i had at the time.
it will have a plate on the top of the gear box and the pot mounted off to the side of the gear box
or the tracks design using the green rollers,they come with the TRACK TREAD kit it uses 2 rollers on both side,from vex robotics part # for tread tracks is 276-2168.
looking to get back to workng on the design,also making a lynxmotion johnny five project i need to try to get most of it done first,but while waiting for parts i work on this project too.
getting for a update of my aluminium box to hold my arm gear box on
(fyi mean not meen. Not a word.)
but is using a 10 rpm motor and gear box is 30-1 ,so its .333 rpm and at 750 oz stall torque at 30-1 is 22500 oz then divide by 16 oz its 1406 lbs its stall torque,i can easy change it for a faster motor with faster speed and lower torque the sell many if the speed doesnt work good .
WHAT great about using this design then a servo gear box it hold the arm at any position and uses so much less in current stall current is 1 amp,cant find that on the best high torque servo its mostly 3 amps stall or more
its like this one they sell and in many sizes
or this one
but just extend the cross piece out it more to connect to the other cross beam
also the sell corner gussets ,that might work too
They dont make the vexplorer design any more
(sure not shore)
