hello ,
i am trying solve service quiz . i have created a ‘start_bb8_move_custom_service_server.launch’ which will launch the service to move bb8 robot in square motion. when i call this service using - rosservice call /move_bb8_in_square_custom ,everything works fine the robot moves in square motion .
However, when i create a launch file which will call client.py to call the service , the robot does not move and it does not even show any error.
Hey Kartiki,
Welcome to the Community!
Before you blame the launch file, have you tried running your client.py manually and see if it calls the service successfully? You can run your client.py with:
rosrun your_package_name your_file_script_name.py
