H, I’m thinking of purchasing a galaxy rvr. As far as I understand, it comes with an arduino r3 compatible controller.
As far as I can see from the arduino R4 specifications, the R4 is compatible with R3 hats. I therefore wondered if I could swap the included r3 with an r4?
I’d like to write a dumb ros node into the r4, then use a 2nd computer to do the hard lifting to make the rvr do more complex stuff.
I can see no way to add micro ros to an r3, but it seems possible with an r4.
I don’t expect anyone to have necessarily tried this, but I’d just like to know if anyone can spot any glaring obstacles?
We haven’t tried this approach, but your idea is excellent.
The Arduino R4 is compatible with the R3 in terms of pins, power supply, and interfaces, allowing it to physically replace the R3 controller in the Galaxy RVR.
However, please check whether the raised pins on the R4 might come into contact with the rover expansion board when connected. It’s important to prevent any potential short circuits.
The core tasks involve migrating the RVR control code and configuring Micro ROS, which is natively supported by the R4.
Thank you, even without micro ros, the R4 should allow me to do more than the R3. I’ll purchase an R4 and have a play around, then maybe grab an rvr later if i get confidence in the R4. Again thanks for the reply.
