That's right, the iRobot Roomba is now supported by the EZ-B. No more wires! Bluetooth connectivity to your Roomba with the EZ-B. All you need is a PS2 connector (from an old mouse or purchase one new from an electronic supply store).
The EZ-SDK and ARC both support the Roomba commands. There is even a Tone module which allows you to write music on your Roomba
Get yourself a PS2 Mouse and cut the end off but leave a 12 inches of wire. Strip the wires back and use a multimeter to probe and find the ones that I connected in the picture. You only need to connect 2 wires, Signal and GND. Attach a servo plug to the end and connect it to the EZ-B.
In this picture, Signal is WHITE and Gnd is BLACK.
Also notice that this is the inside of the plug. That gives you a better idea of what pins you are connecting.
PS, the PS2 connector will have a little TAB in the center, break it off with a pair of plyers because it won't fit in the roomba.
*Note Before Connecting To EZ-B:: Check the signal wire (white wire) with a volt meter and ensure you have between zero and five volts from the Roomba. If you see higher voltage, you're connected to the wrong port. If you apply too much voltage to the the EZ-B from the Roomba, you will damage the D0 port and will require a chip replacement. Feel free to Contact Us for a replacement chip
DJ on the roomba have you heard of the OSMO HACKER there is black and blue one depending on the serial # of the roomba is it needed on some roomba's to get them working i have a red roomba 4100 model i only get it to clean mode no other commands work i am using D0 pin also in left corner of the Movement Panel there is a round circuit whhen i click on it lights up and click again off

You may be on to something with the need for OSMO HACKER. I have given up trying to control my 4230 Roomba with ARC, nothing works. I would really like to experiment with the Roomba using EZ-Robot, so if you find a solution, please post it.
This is a picture of my hookup. I may have made an obvious mistake.
I can check the sci documentation for those models.
If any of you have time to spare it away, a temporary donation of a unit helps diagnose
we'll send it back when done
I can lend them to you, DJ. I'm sort of a roomba fanatic and have been collecting them for some time. Please email me the address you would like them shipped to.
Which units do you need? the blue 4230? Thats a scheduler 2.0. It does not need the hacker. but I will send it along anyway for the red. So you can fully test it, I'll also send a virtual wall and the the scheduler remote (which, by the way, negates the need for an OSMO as it will detect current roomba firmware and ship appropriate update to any 2nd gen roomba.
The red one... I can lend you one of these too. Yeah that one definitly needs an OSMO, would need to see the unit to know which OSMO, blue or black, but i have both so I'll send them both along.
Pashley,
Check your baud rates. And, also your ports on your computer. There is a program that works well for me and it is called Roomba status. It is a free program , just search for it with google. It allows you to control the roomba. You also have to right click your port on your computer in the device manager and change the baud rate to match the roomba on that port.
There is a website that gives Great support on the Roomba. It is called roombareview. again, do a google search and find it.
Hope that this helped,
;)
roomba status i used before i sent to MEL,also i did have to use OSMO HACKER, some roomba's need it some dont,depends on the year they came out you need to check your # with the right hacker,i have the blue hacker i can loan it out but will need it back since i use it alot zagrosrobotics has it,as protechrobotics has it and info on witch one is needed by the ser# i redesign them for higher torque,and dual battery charging design,working on better optical feedback for the motors
DJ i dont think anything wrong with the SCI commands,just needs a firmware update for the SCI commands to work also hope soon to see bi-directional control ,send and receive commands ,can this be done with EZB
BOB.RUSSO i very heavy into roomba for a very long time,i have about 27 of them i convert and sell as my TURTLEBOT design using ROS SOFTWARE just look up on the internet TURTLEBOT by willow garage its mostly a IROBOT CREATE using ROS software and KINECT CAMERA for navigation ,it uses four 12 inch round decks plus brackets,my decksi made if you look at MY ROOMBA PROJECT in showcase in a few days willl have photos up and code
Hello everyone,
by any chance, is someone willing to sell a blue OSMO/ or lend it? I'll pay for shipping costs and if neccessary I'll pay a deposit as reassurance to return it...
check with Fred. He has one.
