Steve if you are looking for the OSMO hacker dongle i have it, I gives full SCI commands to the older models send me $5 and then ship it back to me when done with it i have over 30 IROBOT roomba's,AND I USED IT TO CHANGE THE FIRMWARE ON IT with the OSMO HACKER

Also did many other mods ,one is took all motors and vacuum parts out and added a shelf inside the dust bin,

second i upgrade the motors to a much higher torque and h-bridge design and added a second battery and special switching circuit to charge the batteries

looking at next to add another optical feedback for the motor to make it quadrature output

DAVE on the hamster idea,what look better is a gyro design inside it or under it

Also STEVE i sell every part made for roomba and neato models very cheap,best seller is the NEATO LIDAR (laser navigation sensor) there are many neato lidar hacks to use it as a navigation sensor

Thank you for the respone,s. I was suprised my old 2 roomba,s operated with EZB thru the SCI. The oldest one had a firmware update from I-Robot years ago after developing the circle dance. That fixed that issue, but gears in the brush motor stripped. It does not move very well either, does a slight turn when it stops movement. I was starting my EZB build with my 2nd roomba white 4000, but it developed a stopping issue after running away and getting stuck. I have resolved my bluetooth range problem by adding a cord from USB port and clipping the dongle on top of my laptop. Since that incident of getting stuck, it keeps stopping after a min. or two of movements(maybe I damaged a drive motor or circuit?) If I re-initialize of movement panel, it might go a little longer than stop again. I did repair the sound issue by replacing the speaker w one from radio shack. I am not sure if cleaning both roomba drives would help? I now started my EZB build w my Create. It moves much faster than the roomba,s. When I slow it down on the movement panel, it no longer goes straight. I am trying to mount things allowing acces to the buttons on the Create. I have read there is a on/off toggle pin on the cargo bay pins? I am hoping I don,t encounter any more runaway issues. Since adding the USB cable, I have successfully navigated it to different rooms utilizing the camera without issues. Maybe I need some type of safety switch to shut it down. I have built a 2 servo head w camera, that I successfully controlled w a nitendo remote. I made a mistake of using the recorder with the remote and now I can no longer save files with the recorder. It must have been too big of a file. I tried updating ARC, creating a new file with one servo, but still could not save a file with the recorder. I even tried a restore on my laptop, to the date prior to the file, but the restore failed stating unspecified error, did not restore. I also tried a new file and saving to the cloud, but no luck. I am learning and having fun. Love my EZ-Robot kit. Thankyou to everone who responded. Dave, Moviemaker, Robotdoc, Skater, etc. I will do pics. Steve S

STEVE S havent had any problems with my 4200 series or ICREATE'S MODELS with commands using EZB Movement Panel OR using roborealm AND other Movement Panel software

If you need a drive motors i have many cheap or my new higher torque design on how to build it

STEVE S here is a link to my EZB roomba project

my EZB roomba project Also made a turtlebot platform using roomba with ROS LINUX software

Thank you also to robotmaker(I may eventually try to repair my roomba,s). My plan was to build w roomba first, to get all issues resolved, without damaging my new Create. Do you have brush gears and what is the price? Both units have stripped gears and drive issues. I have a goal of directing my robot to a specific rooms and I want to build or buy arms. I was going to load recorder files to direct it, but that is not viable at this time. My Email is [email protected] Steve S
