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
What color do you need?
Pashley, do you need to borrow one as well?
Bob,
I've got a Roomba Discovery 4210, serial number is with barcode and digits, it was manufactured 22.09.2005. I need blue OSMO. Previously I bought Scheduler remote + DIN-to-USB cable to update its firmware, but all it does when connected is power up the unit and displays 'DONE' (almost instantaneously) on the scheduler display. Later I read that blue OSMO is needed to update unit older than xx. October 2005. and cannot be done with scheduler remote.
Would you borrow or sell one?
Bob.Russo , Attached is a photo of my Roomba collection. I have been trying for a year to find one that works with EZ-Robot, but alas no luck. Your recent post has given me new hope. Please tell me what arrangements I need to make to borrow an OSMO. I thank you.
The Blue single button Roomba should already have the Open Interface firmware and work with the EZ-B.
Ok, here's what I propose; a round-robin swap.
That's faster and cheaper for all of us than back and forth to me.
I have every color so I'll send them all. Take all the time you need to get it right - don't rush it and brick your Roomba. But please know that these are treasures to me and I will miss them very much while they're away and probably cry if they don't come back.
All agreed?
Send your shipping info to me at [email protected]
Oh, Pashley. On another note. I was able to power the EZ-Robot board right from the Roomba battery. I'll dig out my project (its in the attack. I got frustrated with it) and figure out how I did that. That might take a bit though. I'm into smart things, but I'm not smart.
I agree Bob,
I promise to do my best so you won't have to cry
I'm sending my shipping info right away.
Thank you for your good will on helping us!
