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
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.
