Networking
For details on setting up wired and wireless networking connections to your Clearpath robot, refer to the robot-specific tutorials, such as the Husky ROS 1 tutorial.
Contact our Support team at support@clearpathrobotics.com if you have any questions.
SSH and SFTP
Clearpath robots ship with an SSH server operating on port 22 for remote login. This server also supports sftp for file-transfer to/from the robot if needed. By default you can log in using the default username and password for the robot.
Internal Networking
All Clearpath robots use the 192.168.131.0/24 subnet for any permanently-installed network hardware. This includes,
but may not be limited to
- the robot's primary PC,
- the robot's MCU,
- a secondary PC (if present),
- any cameras, lidar, or other sensors that communicate over ethernet, and
- any long-range wireless radios.
The 192.168.131.0/24 subnet is statically configured; all devices are configured to use a static IP address, and
there is normally not a DHCP server operating on this subnet.
For a list of standard payload IP addresses, please see network IP addresses.
Clock Synchronization
If your robot contains multiple computers, their clocks must remain synchronized to allow proper communication between
ROS nodes running on each one. Clearpath configures the computers to use chrony to synchronize the clocks, with the
primary PC being the authoritative source for the others.
For details on configuring chrony, please see configuring NTP.
