lot of are using a roomba 400 series with EZB and its a great platform for any type of robot design with decks or without,mostly go very cheap on ebay $35 average price
when you remove all vacuum motors,and parts you have a lot of room,plus 2 high current switches (1.5 amp) and 1 low current switch (500 ma) plus auto docking and charging ,total weight it can carry is little over 35 lbs
so i design and made a motor upgrade kit i am looking to sell soon
it will double the carry weight,has changes to main PCB and higher torque motors
szoon as i finish testing the themal and current protection and few other tests will be selling it
I have the Roomba Create unit and I used it as my robot platform. However, it hardly moves. I need to squeeze more torque from my Roomba.
Another option I have is to forget about the Roomba and get an h-bridge and motors.
Just the basic roomba without motor upgrade and top deck $45 plus shipping,i think about $15 more
for relay and control circuit,TOP DECK IS ABOUT $12 from zagro's its 12 inch round abs deck
If you use a H-BRIDGE on the motors ,.may not be able to track navigation or return to home base charger
Motors are longer.so i cut out a hole where the dust bin was,plus mosfets all 8 of them need higher power or 2 in parallel,plus current sense resistor needs to be change.
inside brackets change a little using angle aluminium and it will have a abs plastic on top of the angle aluminium
this one shows the deck mounted without standoff on the top and my itx box
only i have standoffs on the underneath it
i do have more then 5 complete without the motor upgrade
here is a photo with all my decks mounted and same one in my roomba project
Can I do the upgrade to my Roomba Create? So all i need is the stronger motors and the pcb modification?
they are longer and same DIAMETER,so the length may be a problem and the wheels need to be on a lock position ,with the kit that comes with create package
I never open one yet,and i bought 2 of them too
Do you have the upgrade kit on eBay?
SATERDAY night will work out the mosfets and part #,i know i dont have any in stock
o mostly get them from digikey,i buy about 25 to 50 at a time
SATERDAY night should have all the info you need
the original part #'s are 2SB772 for PNP and 2SD772 for NPN
when i look at it fast it look like R12,been awhile sincei work on my design i have so many projects
Cant wait for march 28 NO more work ever,(might in 20 years go back to work) to get SS
also order 50 each of each type,npn ,pnp and 3 watt resistor
its 2 500ma switch and one high current switch at 1.5 amps
great for torning on stuff like relays or power to the kinect like on the TURTLEBOT design,witch my base design is based off it,just only made it higher and another deck,i hate low height robots a little
i am getting the parts in today,
On the motor change i dont think you have a gear puller ,so i will replace the gear and cut the shaft,second it fits perfect in the housing ,but will need to make hole in the dust bin area.
And make it so the motor assembly wont move up and down (wheel lock)
will post photos on it.
