Hi everyone,
I’m Axel, new to the forum – so please forgive any rookie mistakes in this post 
I’m currently working on an autonomous rover project that I’ve built myself. The goal is to have it follow a pre-defined path outdoors with centimeter-level accuracy using RTK-GNSS. At the moment, the rover is controlled via a remote control that sends signals to an Arduino, which in turn controls the motor drivers.
Now I’d like to transition the system to fully autonomous operation. Here’s the general idea:
The Arduino will still handle motor control.
A Raspberry Pi or Jetson Nano would act as the “brain” of the system, calculating and sending movement commands to the Arduino.
Routes will be planned in software beforehand.
I’d like to see the rover’s live position and status on a nearby laptop (e.g., via map or path visualization).
That said, I’m totally open to better suggestions for the “brain” if anyone has ideas that are more suitable than Pi or Jetson.
A few more details:
Operating area is about 500 m² and I am Living downton Hamburg.
There’s no fixed WiFi in my garden, but I can provide mobile internet via a SIM card if needed.
I have some experience with Arduino and Raspberry Pi, and I’m comfortable with soldering and basic wiring.
RTK and GNSS are new to me, so I’d really appreciate your advice on:
Which RTK GNSS setup would you recommend (e.g. base + rover modules vs. correction via NTRIP)?
How could I best transmit GNSS data from the rover to my laptop for live tracking – especially without relying on a shared WiFi network?
Any general tips on structuring communication between components?
Thanks a lot in advance – really looking forward to learning from the community here!
Cheers,
Axel
P.S.: I originally planned this in German, so if anything sounds odd or unclear, feel free to ask for clarification!
