Connect to Devices coBridge

coBridge is an open-source edge software provided by coScene, currently supporting ros1 noetic, ros2 foxy and humble versions. coBridge runs as a ros node on the robot side and interacts with the cloud through websocket connections. After establishing a connection with the cloud, coBridge can subscribe to ros topics and call ros services based on cloud commands, enabling real-time robot status monitoring, remote command deployment, and other functionalities.

Prepare coBridge

Please refer to Install coScene Software Using APT to install coBridge. Launch the ROS node afterwards.

  source /opt/ros/${ROS_DISTRO}/setup.bash

  # for ros 1 distribution
  roslaunch cobridge cobridge.launch

  # for ros 2 distribution
  ros2 launch cobridge cobridge_launch.xml
