How To Connect Ezb To A Create 2

I have been looking on the forum for a wiring tutorial for the ezb and create 2. There are a lot of ideas and very complicated ideas that seem to work but no simple tutorial to connect ezb to a create 2.

Please let me know if there is a tutorial or can you provide me with one.

Thanks,

Hi Ellis, That is my fault.... I put the Roomba into "FULL" mode to run some tests and forgot to change the code back to the "SAFE" mode.

I will change the code in the project, but just so you know whats going on here is the change I'm making

Quote:

uartinit(0, 1, 115200) #UART port 1 sleep(20) uartWrite(0, 1,128,132) #Init iRobot create and place in full mode

I will be changing the "132" to a "131" for the "SAFE" mode which enables sensors. It will just stop when it bumps its something is it really not doing a cleaning mode and wont try to find its way around the room after a bump

If you'd like to look at the complete list of commands here is the iRobot OI spec www.irobot.com/~/media/MainSite/PDFs/About/STEM/Create/create_2_Open_Interface_Spec.pdf

It can be a bit hard to follow, but once you see some example, it will make sense

I'll keep adding features and am considering actually writing a EZB Roomba tutorial unless someone more experienced wants to do it. I'm open to ideas and suggestions starting with which advice on Roomba models a new user should pick... e.g. don't pick a 440 as it has no charging pads for docking

Thanks Frank

The info is great. I would be very excited about you writing a tutorial on the new version create 2. I think there is a lot of people out there that would love to use EZ-Robot to control their Create 2. Looking forward to it.

Hi Nink, Thanks for pointing that out...looks like the adafruit site didn't like the ref from EZ-Robot Forum although the embedded link looked fine.

I changed it to the iRobot site which is a better location anyway and that works.

Good catch, Frank

Roomba turned up $200. Missing power cord (same as my Apple TV) and the invisible wall was broken (broken wire) but works great. Cleaned the house well :-).

I went to find my old roomba red din connector but it was lost, so I cut the end of an old mouse off. Problem was it only had 4 wires and none were ground (pin 6 and 7) so maybe this is why people are having trouble. Remember when you look at picture of a port your wiring for plug is mirror image so you may mix up pins. Any way I grabbed 2 jumper wires and just connected direct to EZB and works great.

I will buy a connector. Here is a photo to show exactly how it is wired to work with Franks demo.

Found my tripod. How are you guys attaching iPads. I put some Velcro on mine but I think we need to make a pan tilt and spin.

Any thoughts on making a body for the robot?

Hi Nink, I'm glad you got your Roomba working.

For anyone else who does not want to solder on that small connector, here is a cable I'm using from gumstik.com. No worrying about soldering to the wrong pins store.gumstix.com/cbl013.html

The real beauty of it is that you can just clip it unto your EZB Controller with one additional M-F breadboard jumper... no soldering at all!

This is the kind of stuff I thought about putting in a Roomba Basics tutorial

Hi Nink, I think you should look into a special iPad camera mount like this...

I'm acutally using a tripod that came with that removable iPad/iPhone head

I'm not planning on trying to motorize an iPad mount, but would be interested in your design. You wouldn't have to impement the PAN function as the Roomba could provide that axis of movement

Thanks, Frank
