Other than making sure you wired it up correctly, did you set the Roomba control panel in settings to use the new 500 series protocol (115200 baud)? By default it is set to use with the 400 series...

Hi Richard,

Yes I checked the 115,200 baud box also in the settings. Does the other option "use old protocol" also apply in this case? I tried checking and un-checking, but nothing happened mad

There is a green light on my EZB v4. Just wondering when you press the init button, is there any notification that signals whether the Roomba is successfully connected to EZB? I do not hear anything when I click on the Init button.

Is it a solid green light on your ezb? If it is flashing you are not connected to ARC in which case might be your problem... The old protocol is for the old 400 series, you have the 500 series. Not sure if the roomba will indicate a connection... Hopefully Robot-Doc will chime in as he is the Roomba expert around here...

This may sound weird, but after you initialize the Roomba try clicking on clean button before using the forward, reverse, left and right directional arrows....

Thanks Richard. Its actually a solid green light on the EZB. I tried the clean button but no success! I hope Robot-Doc comes to my rescue!

Have you downloaded the latest version of Ez B ?

I've not had much success using the 500 series Roombas and the Pre-defined Movement Panel of ARC.

Once in a while clicking a button will generate an action but it is not consistent. I switched over to sending commands to the 500 Roomba using Serial port 0 with much better success.

If you want to keep using D0 for Roomba control you might want to consider switching to the 4XX, 4XXX, Dirt Dog, or Create robots.

@Doc... I guess if you throw your serial commands in the custom Movement Panel you would at least have a working movement panel...? This way you would have keyboard and joystick control as well....
