ROSbot 2 PRO: Not able to access the topics from on the laptop

Software

Thank you for the instruction. Below I prepared some suggestions:

  1. Sometimes there is a problem with communication using CycloneDDS via WiFi. The easiest solution that my help is restarting ros2 daemon stop && ros2 daemon start. For cyclonedds you can read a bit more here.
  2. Your compose is different from the default compose sent in the message above. Please restore the settings and see if it helps.
  3. If you want, you can use a newer, simplified version of compose without a separate service for microros.
x-common-config:
  &common-config
  network_mode: host
  ipc: host
  restart: unless-stopped
  environment:
    - USER
    - ROBOT_NAMESPACE

services:

  rosbot:
    image: husarion/rosbot:humble-0.13.1-20240201
    container_name: rosbot
    <<: *common-config
    devices:
      - ${SERIAL_PORT:-/dev/ttyUSB0}
      - /dev/bus/usb/ # FTDI
    command: >
      ros2 launch rosbot_bringup combined.launch.py
        mecanum:=${MECANUM:-False}
        namespace:=${ROBOT_NAMESPACE:-rosbot}
        serial_port:=${SERIAL_PORT:-/dev/ttyUSB0}
  1. You can also use the latest version wrapped in snap, which has a more user-friendly API.
