Hi. New member. I’ve built a number of ROKR kits, and just started on LG503 Marble Explorer. I’ve just started building the Marble Explorer kit. On page 5 of the instructions there is a QR code for "motion assembly instructions.” But that QR code goes nowhere. I’ve looked in the instructions section here and there are forums for the LG501 and 502, but nothing for the 503. Any idea where I might find the right link for those instructions?
Many thanks.
Maybe @Robotime can help. I have not done this one. I hope you can find answers.
If you don’t get a reply here you can try direct messaging @Robotime. They’re very helpful. 
Welcome to the community, @bobmeyerweb. Maybe @CustomerService can help too, they’ve been uploading instructions for some kits here. 
Thank you.
You’re welcome @bobmeyerweb
Hello, we have double-checked and the QR code can be scanned normally on our side. Could you please send us a photo of the QR code you are trying to scan so we can help identify the issue?
Thank you for your reply. I’ve uploaded a photo of the barcode, and the cover of the instruction booklet, in case there are multiple versions of that. I’ve also included a screen capture of what my phone displays when I scan the barcode. The same thing happens when I try to scan other barcodes in the instructions.

Not on my phone, it doesn’t. But I think I’ve figured out why. Your link opens in Facebook. I do not have the Facebook app on my phone, and never will. You shouldn’t make Facebook a requirement to view your videos. Just link to YouTube.
Hello, we will report this issue to our team and check whether the video needs to be uploaded to YouTube.
