ROS transform/synchronization issues Hello everyone, I have a robot equipped with a stereo camera for perception and an

2018-07-30 09:01:01 -0500 marked best answer ROS time synchronization in isolated local network

Hello everyone,

My robot consists of three processing units (master, slave1, slave2) connected via an ethernet switch. They form an isolated network so there is no internet connection. For time synchronization i simply used to do ' ' in the .bashrc of the slaves in order to get the time of the master which seemed to be working. After further testing I noticed that this is not good enough for time synchronization. I read through http://wiki.ros.org/ROS/NetworkSetup and also followed the link for isolated networks at the bottom but don't really understand how to actually do this.

How can I time-synchronize the machines in my local isolated network? Any help would be appreciated. If you need any additional information please let me know!

Greetings
