I am currently working on a robot that I connected to my PC$.$ After that, I opened a terminal, I placed myself in the robot $($that is to say in the raspberry pi card$)$ with the command ssh: ssh ubuntu@$192\mathrm{.}168\mathrm{.}28\mathrm{.}24$ and I typed the command ros$2$ topic list which showed me the outputs for my robot. I then opened another terminal in my PC without placing myself in the robot and I typed the command ros$2$ topic list so that it gives me the same outputs as that of my robot. But I obtain different outputs at the pc level and at the robot level. At the pc level I obtain only two lines namely: $/$parameter$\_$events $/$rosout as outputs. How can I correct this at the PC level so that I obtain the same outputs as at my robot? I am on ubuntu $20\mathrm{.}04$ and on Ros$2$ galactic. For the outputs for the robot it is the ubuntu terminal and for the PC it's the other.
