I created a robot arm standing upright.
When I run the gazebo everything is normal but when I try to move one of the controllers all the arms fall down and I can’t move them anymore. When I run rosservice call list_controller I get an error.
user:~$ rosservice call /mira/controller_manager/list_controller
ERROR: Service [/mira/controller_manager/list_controller] is not available.
I am just getting started and I noticed that when the PID values are close to 1, the arms drop right after starting the simulation, and when these values are increased, I am dealing with the problem given in the title.
Thank you in advance for your help
