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.
Hi there @Techvet! I was actually the one that worked on the setup we had at our booth at CES, where you see the trees and mountains. Yes, I believe most things were O scale, and some HO scale. I bought a lot of things from the local model railroad shop. I got trees, two plastic molded mountains, some buildings, and then a bunch of Lego buildings as our landmarks. I also used a vinyl print of the road, so that we could get a single consistent piece to lay down on the board. It was a pretty large print, so I worked with a banner printer, then cut out the road by hand from the vinyl banner.
The actual floor of the "Zumi World" was 2 wooden boards wrapped in a green cloth and stapled to keep it taught.
Hopefully that gives you some ideas!
Looks like your connection to Robolink community was lost, please wait while we try to reconnect.
