Hi,
Does someone have already mysensor-ed a Roomba bot ?
I'd like to do so (in order to get back some info such as battery, status, etc... and be able to trigger a cleaning program remotely).
This look like pretty straightfirward thanks to the Roomba serial interface and I intend to try that as soon as i will have finished the temperature control of my house...
However if someone as already done that, i'll be interested in your feedbak.Thanks!

Never had a roomba, but i have obtained remote control of my automatic LG vacuum :+1:
I just copied the IR remote commands and transmit them on command from a sensor node.
There is no feedback, but i don't think i need feedback, when the battery is empty it drives back to the docking station. All i can say is that just pushing start remotely and getting home to a clean house is nice ;) -
I'd love to do it for you.
Unfortunately, roomba too expensive in my country :(
Anyway, good luck for your project.
Hopefully, you can share it here -
Hi,
I had started to analyze the communication protocol and the project. I found this site very useful. The problem is the sizing. I'd like to keep everything hided so a very small circuit is requested.@mortommy it's quite easy: Roomba has a serial (there is 7-pin mini DIN socket under rubber cover on top of the device). Communication protocol is well described: https://cdn-shop.adafruit.com/datasheets/create_2_Open_Interface_Spec.pdf
Remember that higher versions of Roomba (7xx+) communicate with higher baud rate (115200bps).There are also couple of libraries (but be careful, one of them contains hardcoded baud-rate, no matter what you declare in constructor :(, I haven't already sent a pull-request).
And the last thing worth mentioning is power supply from Roomba - usually it outputs about 16V, what is enough to power Arduino using internal power regulator, but after connecting to docking station, voltage raises (I needed to replace my one). -
Yes @emka it is not difficult, I have already wrote a sketch. The problem it is, as I said before, and as @vorowski said, an hardware problem, especially with the latest series 8 and 9. You cannot leave the electronics components outside and the space under the handle it is not enough. If you look for a solutions in the web you'll find even two commercial solutions to control roomba, but for the new series they propose some dirty fixes to fit the hardware.
I'm thinking to control roomba via an IR send/receiver. -
this is the code I used....

Hey all,
I made a Roomba IR scheduler for my Roomba 500. I used Mysensors icm with Pimatic. On a defined time or condition in Pimatic I sent for about 10 seconds the IR command to the Roomba. Which will start the robot to clean and leave the dock. With a LDR on the dock LED I can measere the amount of time the robot is cleaning. The same Mysensors node does also measure the room temperature and humidity of the living room where my Roomba dock is.Emiel

For quite a while now there has been information on the net on how to build serial cables for the roomba and the documentation for controlling it from such a cable. I found this little bit on connecting the serial port to an arduino. http://www.netfluvia.org/layer8/?p=127 Seems like it should be pretty straight forward with this info to be able to MySensorize it. Looks like they do their communication with an xbee, but the basic concepts should be the same.
