OSKR basically is a software solution to turn any Vector into a development machine. On this it is possible to develop new firmware features like behaviours, animations or sounds that run without the need of an external server and/or the Python SDK. This of course is not something for the average users, but for the more technically inclined.

So far information is scarce, especially as I did not get my invite and instructions yet.

OSKR documentation - Here you finde the instructions to turn a retail Vector into a development version via OSKR.

For the Vector Web Setup you need Chrome as the browser (other webkit based browsers that support Web Bluetooth should work theoretically, but there are problems, Chrome is confirmed working) and a device that supports Web Bluetooth. Since desktop computers usually are not equipped with Bluetooth you may want to use a laptop, or buy a Bluetooth dongle for your desktop computer. Not all dongles may be compatible. I can confirm that this one works: TP-Link UB400 Nano USB Bluetooth 4.0 Dongle
