What would be the best way to set the network if multiple robots are involved?

@Clearpath 4 года назад

Depends on your setup. You could set the IP addresses of each robot to be unique, but this likely isn't what you are looking for. If it is over wireless, make sure that your DHCP gives a different address to each robot. You can set up static DHCP to make it easier to work with. Then you can use multimaster to coordinate the different robots in the same ROS network.

@fayyaz I'm also working in this kind of project. Could you share your email

I'm not able to get the rostopic list from pc. i can see through the ssh

@ShravistaKashyap 2 года назад

Hi, I have followed your tutorials and I have an issue, and modified precisely the same way you told me. But when sending the rostopic data from the laptop to the robot, the robot cannot get the data, but rostopic list will show the topic name. I have tried disabling the firewall too but no effect. What could be the possible solution to this?

@Clearpath 2 года назад

Hey Shravista. Send a message over to our support team (support@clearpathrobotics.com) and they should be able to get it sorted out for you!

@talhaejaz7651 Год назад

I have the same issue and with this one and sometimes it's doesn't connect with an SSH its just loading after writing ssh administrator

@ShravistaKashyap Год назад

yeah finally found the issue. it is firewall that is blocking the communication. finally resolved. thanks for the help. stackoverflow.com/questions/73640869/data-is-not-seen-from-the-ros-robot-when-published-from-the-workstation-laptop

Do you run roscore before rostopic list? Because if I don't do that I get - unable to communicate with master. If I do run roscore, I don't have a long list of topics. Just /rosout and /rosout_agg I can ping the jackal's IP and host name and get a response though, so I'm not sure where the disconnect is.
