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
Upgrade to ARC Pro
Unleash your creativity with the power of easy robot programming using Synthiam ARC Pro
anyone sucessfully do this?
Isnt working for me.
COM8, the lower of the two that the blutooth connected too.
I did. though it defualted to 8.
FYI, i just tested a ping sensor and a servo. Each work perfectly. So i know the board isnt fualty.
I switched to a Create, which accepts the same SCI as a roomba, so theres no question. Same performance.
Is it possible i have the wrong pins? I'm using 3 and 7.
(Looking down into the female roomba port)
One difference i did notice, in your video you have a send init button but none exists in this software. is that it maybe
You can try using the Script Console (F3) and send commands manually according to the datasheet.
Just to see if something funky is going on.
What happens if you use the roomba tone control? Does that do anything?
I wonder if there is a command in the newer firmware that i'm not sending that i'm supposed too. I know the command set is the same, but maybe i'm sending something that isn't right.
I'll take a peak
So Sorry, DJ. These Dusty old Roomba's are years and years old and been used everyday since the day I bought em. Been repaired several times and still trucking. Never thought the serial port could collect dust, but come to find out. Cant expplain why the create was so dusty though. whatever.
Thanks for trouble shooting for me, I NEVER would have thought the issue if i wasnt sure that everything else was right based on what you said here.
i see you can only send not received
i got my board and camera in this week and cant wait to use and looking to buy a few more for many many robot hacks,have a wall-e,rad,R2-D2 small and large and lot more robots ready to be hacked
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.
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
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.
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,
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
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...
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?
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.
1. I'll send them to dm39910 first. (Shipping cost is on me.)
2. dm39910 then sends them to Pashley. (Shipping cost is on dm39910)
3. Pashley returns them to me. (Shipping cost is on Pashley.)
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.
Send your shipping info to me at Bob.Russo@US.Army.mil
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!
I took precautionary measures prior to this payment just in case.
As soon as the product was removed I contacted my credit card company with the issue.
Yesterday I reported to the CC Company that it appears the item was shipped and that it is on its way.... So.... I am currently waiting to see if the product really arrives and is as described.
Will update end of the month.
@Robot-Doc this was the transaction I was talking about in the email. If this really arrives I will be really joyful. If not I will buy the one you offered.
I have already been refunded though
