Whoa that's awesome

mostly not looking to make much money,just for the parts mostly so many projects not enough time in the day

Hi robotmaker, Do you still sale your Roomba motor upgrade kit? 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.

Yes still for sale,mostly it done except motor upgrade,should be ready in a week, and depends what you want deck on top or and in bottom ,dual battery design

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.

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

Very nice! Can I do the upgrade to my Roomba Create? So all i need is the stronger motors and the pcb modification?

BOARD is about the same as roomba series,but i dont know if the motors will be able to be mounted 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

Ok and what if I will cut the Roomba plastic cover? Can I replace the motors?

yes then should work,motors i found that had a much higher torque is the ones off roomba BRUSH motors,i think its RS385 motor also,i need to check

so all i need is to put this new RS385 motor instead of the originals?

yes ,plus put mosfets in parallel ,so you need 8 total plus 2 sense resistors in parallel

Cool. do you sell it or should I buy it from ebay? Also can you provide the schematics how/where to connect the mosfets?

i have a lot,on the circuit will how to draw a circuit,or you can buy higher wattage mosfets and just replace them,will get a part # for the mosfets

Sound good. Do you have the upgrade kit on eBay?

not yet,i had the motos up on ebay,and forgot to put them up again,will relist them

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

Thanks, tell me when it's up

ok ,it uses 2 pnp transistors and 2 npn transistors new part #'s are MJE200G for npn and MJE210G for pnp,it will take about a week before i get them from digikey and on the resistor needed is a 3 watt 1ohm in parallel with R41 and R12 on pcb

the original part #'s are 2SB772 for PNP and 2SD772 for NPN

not being picky robotmaker but on the resistors at the top of the PCB next to the two H-bridges they are marked R41 and R112.

YES thanks you are correct,and not been picky 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

Did you get the parts for the upgrade kit?

i think about monday will have them in,was order them tuesday

also order 50 each of each type,npn ,pnp and 3 watt resistor

ALSO made a small mistage on the first post about the 3 high current switches 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

@robotdude

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.
