@robolink_leila , @rdmueller
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.
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"
Thanks for the feedback @pk123456 !
We are having issues with Jupyter on our end as well and we have our team working on it. In the meantime, try running offline and make sure only one is open at a time. If they get stuck, go to the "Kernel" tab in the toolbar and select "Restart and clear output".
The hostname is zumi1234 (or whatever 4-digit ID your Zumi has) and the password is "pi". You can also open a terminal session in Jupyter Notebook.
The board has I2C and UART pins for hobbyists. Keep in mind that the current draw for whatever component you choose should be low.
You will need lots of training data for this to work. For those starting AI it can be a little complicated, but we are working on creating a field with lesson plans. In the meantime, craft stores can offer cheap and easy materials to make a simple field, and I would start with writing programs that do simple color detection while navigating around obstacles. We'll update you when we get those tutorials out
@Aladdin Hi there, we recently published our FAQs which may help you:
Why can’t I connect to WiFi?
If Zumi cannot connect to your network the first time, it may not have communicated information in time. If the connection fails after multiple attempts, your network may not be stable or you are trying to connect to a captive network (like a coffee shop or airport). Try again or let me know if you are having this issue consistently. We have our team working on it!
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.
Looks like your connection to Robolink community was lost, please wait while we try to reconnect.
