Topic: Hacking a Roomba's button panel (Read 700 times) previous topic - next topic

I've got a Roomba 4000 based project I am working on and would like some advice.  I have removed the normal button interface because I needed the space on the robot.  However, after working with this for a while, I realize I would like to have either a battery kill switch or the button panel back to save me the hassle of pulling the battery whenever the Roomba gets confused or cranky.

I kinda mapped out the pins on the button panel, but I see a bunch of resisters in the corner, so I'm a little leery to just go shorting pins with a contact switch without asking for advice.

I don't have a blog or anything (I suppose I should get one started lol), but my latest update on my project is here:

Although that was yesterday before I really got into it; I've made some good progress on it.  For example I can move the arm with the PS3 controller now :D  Well 2 of the motors in the arm at least.

Do you think I could just short pins 8 and 9 and be ok for making a new power button?  I wasn't able to get a good feel for how the resistors were connected.

Hi allenonmage,

I can't answer your question, but I can say that I'm impressed with your project.

I'm looking forward to future posts showing your progress.

Thanks!

I started testing a little bit more and who knew the continuity tester function of the volt meter would tell me how to turn on the LEDs?! lol...

See attached for my new notes.

I know that one of the pins puts out voltage, but I'd have to connect the connector and I just realized that i screwed it together last week :-/

So next is trying to figure out how to orient LEDs to not fry them.  Maybe... I might leave feedback to the Arduino and serial interface and just have the power button to the Roomba.  But the power LED is so close... But it's 2 colors... ah complicated stuffs
