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.
@krishna Please share a screenshot of the output when you run the following:
from zumi.zumi import Zumi
zumi = Zumi()
If Zumi is still not going straight, take a video of Zumi driving as well as a video clip of Zumi as you gently turn the motors with your hand. If anything feels stuck or dislodged, then please let us know!
@gormican In a few weeks we will have a demo for you all to try for training Zumi to recognize different hand gestures. For your own image training, we are working on a platform to make training easy and fun. You should see it by summer
@jimmykh Unfortunately, you need to wirelessly connect to Zumi. We are working on some possible solutions but in the meantime, you may need to disconnect the wired ethernet or enable your wifi if the device can support it.
