Thank you for your help! I checked my laptop Internet connection, but my laptop doesn't have any wired connection and ethernet cable connection. When I connected to Zumi via wi-fi, Zumi said " You Found Me". After that, when I entered 'zumidashboard.ai' in Chrome, it was the same display, but when I changed to Edge, I was able to go to the page "Hi, I'm Zumi 1234". Internet Explorer did not work as well as Chrome.
Anyway, my problem seems to be solved. Thank you very much.
It appears my Zumi is still unable to connect to wifi!
It seems to me that I had it connected with the original firmware, but after a update (maybe) I wasn't able to connect.
I've had it sitting for a while but got notification of this post a couple of days ago, so thought I'd give it a try again.
Any way I've tried to get it to connect using a Chromebook, and later using a desktop running linux mint 19.2 (chrome browser) with no luck.
I can connect to the access point it creates, and it does show a list of wifi APs in the area, but fails to connects after a preset amount of time, try again doesn't work, and Worse than all that it has a very hard time getting back to it's own website - most of the time it doesn't, even resetting and starting over doesn't work.
It seems to me that one point I was able to get to some tutorials or something in off-line mode - but since a few days ago I've not been able to even do that.
On boot the screen also show v1.0.0 do I need to update the screen controller (arduino I'm guessing?) firmware as well (?) if so how and where do I get that firmware at ?
We will take your feedback into consideration, thanks! For your camera issue, you may be seeing an error such as "Camera not enabled". Please check that the camera cable is connected to the RaspberryPi. Sometimes it can become disconnected. On the camera itself, the cable may also pop off. Gently push these back into place and try again. Let me know if you have any more questions!
We do have a Zumi intersection underway! In the meantime, here are a few ideas:
Use a whiteboard on a table as a field and use whiteboard markers to draw and redraw roads
Build obstacles out of blocks or household objects
Print out a course on regular 8.5x11 paper and tape it together
If you have any ideas, please let us know!
@robolink_leila Hi Leila, I think Arnold said he found that the battery was the problem. We found that one of the battery leads wasn't soldered. If anyone else gets this problem they could open the tape and see if both battery leads are well soldered.
This also happens if you refresh the zumidashboard.ai page after you have disconnected from Zumi.
I had it happen when I rebooted and the last page I was on from my browser was the dashboard.
I thought maybe Robolink owned the domain name, but looking again, I do see the "parkingcrew"
The switch has to be in the "off" position while the USB is plugged in for Zumi to charge. If you plug in the USB without switching it off (and seeing the red LED) Zumi will not charge. Further explanation can be found in the FAQ.
@haru If you are sure that the cable is connected on both ends (including the "Sunny" connector"), you may need to go into the terminal and manually enable the camera.
To open the terminal, you can follow step 3 from the beginning of this tutorial. Once you open the terminal, there is no need to create a new directory. Type the command sudo raspi-config and you will see the configuration menu for the RaspberryPi. From the options list, select "Interfacing Opotions". From that menu, select "Camera" and make sure to enable it. The system will ask you to reboot. Log in again and try the code. If you need more explanations or something is still not working, let us know and we can set up a support call.
