I have a new Zumi that is not charging. When the usb charging cable is plugged in and Zumi is powered off, there are no LED lights and the display is blank. When I turn Zumi on, it is showing 0% battery. I have tried different cables, I have also checked the power slot and it seems okay and not faulty.
@timmytomate We recommend not using the screen draw functions in your for loop in conjunction with the forward_step(). Any of the screen drawing functions take around 300 ms, which will delay the forward step. Let us know if this helps!
I'm not sure about Visual Studio but you can ssh into Zumi through Pycharm and access the files using their editor. You can configure a remote host with the username (pi), hostname (zumidashboard.ai) and password (pi). I think this feature comes with the professional edition only but you can try it or look for a similar feature with your IDE of choice. I hope this helps!
Unfortunately, the current circumstances have paused developing competition materials since we cannot host in-person competitions. However, you can use our lessons to create projects with your mat! Feel free to share them on the forum for other community members to see. In the meantime, we are working to release more wizards to help you train your own models and navigate the course. Thank you for your question!
Hi @gema0024! Unfortunately, our latest release has been delayed. We will be having a release this week with the regression wizard but the color training wizard is undergoing a few tweaks to make sure you have the best experience. Thank you for your patience and keep checking back for updates!
Sorry to hear that! Can you take a look at your OLED (preferably without the shell) and let us know if it matches the one in the image below? You are looking for the bottom right numbers that are circled on the image.
Hi @jimmykh We are working on a new application for the color training so we temporarily took down the original lesson. Thanks for waiting! If you would like to access the old function you may also open the logged lessons and visit a previous version of the content.
@thang123 Sorry to hear that! Our team would like to schedule a call with you to see the cause of the issue and try and resolve it. You will be receiving an email shortly to the email associated with your forum account. Thank you for your patience.
@brennsteph You can build any track you would like and use basic driving commands found here to navigate! To learn how to use IR sensors and camera to make decisions while driving, you can follow our tutorials on Workbench. If you don't want to make your own field, you can purchase one here from us. If you are still having doubts or technical issues, use this link to set up a time and I would happy to speak with you. I hope this helps!
Hey @DogEars, sorry for the delay! If it's saying "Zumi can't wake up" that sounds like the SD card may need to be re-flashed. When you say you flashed the latest firmware, are you flashing it from your computer, or do you mean a regular update?
Either way, I'll shoot you an e-mail to coordinate mailing you a replacement SD card. Meanwhile, if you could send the SD card you have so we can figure out what's going on for future cases, that'd be great.
@mrschunsclass There was a mistake in the labeling of the battery. Sorry about that! Flip the battery in such a way so that the wire is pointing toward the back. If it's a tight fit, you can remove the dual-lock velcro and try orienting the battery vertically instead. As long as the connector reaches and nothing is puncturing the battery it will be fine. Thanks for the question!
@JY2010 If you are still seeing that screen then your camera may have dislodged again or the cable is not properly inserted to the RaspberryPi. I would recommend keeping the shell off as you adjust it and then once you have it working, you can put on the shell.
