I know this is early, but does anybody have any links to examples of things you can do with the RVR. We have Raspberry Pi, Arduino (with cameras, sensors, etc.), Micro bits, etc. We would just like to be able to do something more than drive/program it.
I keep watching the YouTube video on how to connect a raspberry pi https://youtu.be/gsDXe0gErxQ
For an optimum autonomy, we would recommend using a low power Raspberry Pi, such as the Pi Zero. You can always use the Pi 3 and even Pi 4, but the playtime of the robot will definitely go down. We cannot guarantee that RVR will provide enough power for the Pi 4, since its specification requires 3A at full load, and the RVR expansion port can only deliver 2.1A.
It is also possible to connect an external battery to the Raspberry Pi 4 to provide the extra power needed.
