Hey I'm looking for suggestions here and answers. I've never hacked a roomba so I'm being a good little mad scientist and doing some homework. The booze robot I would like to take advantage of the auto dock and charge feature. Does anyone know how that works? Also I planned on controlling the roomba through the ps2 port but far as I know that's a one way connection to send commands. Lastly does anyone know how to utilize it's bump sensor so ezb can read the bumps. If I modify it so ezb can read the bumps will this throw an error and cause the roomba not to function? These answers are super helpful with this coming weeks work where we should see the beer butler have a working chassis.
You might consider building a TTL - USB comm cable for your Roomba also. There are features you can access within your Roomba like battery charging reports as well as demand diagnostic reports that provide detailed info on every motor and sensor within the Roomba.
You can find 7 pin mini din connectors HERE
Ttl to usb? Can both usb and the ezb be connected at the same time for this?
No, the last info is provided in addition to the one way communication available with the D-0 port on your EZ-B. There are other features available within the Roomba alone that require a two-way comm link and a PC with a Terminal program like RealTerm or HyperTerm. The additional communications cable can be used with your PC to troubleshoot issues that may develop later inside your Roomba.
Thanks guys , I will grab a ps2 plug and go from there today.
jstarne1, I purchased a ps2 plug from Radio Shack because the mouse cords did not have the correct wires. Steve S
Just for EZ-B members I can build a complete cable to connect the EZ-B V3 board to the iRobot Roomba for a small fee and shipping. Send me an email if interested. Email address is posted in my User Details.
Hmm I will see if I can get a keyboard and cut it's wire off and compare them. I don't want to screw my Roomba up.
