The Advantech ASR-A702 is the Jetson Thor carrier board with the most Ethernet ports — 6 ports, and it's actually purpose-built for exactly your application: Advantech describes it as an "AMR control carrier board for NVIDIA Jetson T5000 / T4000 (Jetson Thor) modules," so it's aimed squarely at autonomous mobile robots. advantech... +1advantech.com ↗“AMR control carrier board for NVIDIA Jetson T5000”advantech.com ↗“io.ethernet_ports=6”

Runner-ups (4 Ethernet ports each), in case the ASR-A702's –10 to 55 °C airflow-conditioned thermal envelope is a concern for your AMR — these are all Thor-supporting carrier boards with wide-temp ratings:

One thing I couldn't determine: whether the ASR-A702's six ports are all RJ45 copper or a mix of copper and SFP — the catalog lists the count and 10GbE max speed but not the connector breakdown; the datasheet linked from Advantech's product page would confirm that.
