Robot Falled off in Simulation

[kaicongw]

Hello,

I was trying to run simulations after I installed ros2_SimRealRobotControl following all the steps in the ReadMe (including the new IFRA_LinkAttacher ROS2-Gazebo plugin). However, when I launched the Gazebo simulation environment or the Gazebo + MoveIt!2 environment, my robot always falled off without maintaining its home position. I could not run any other programs to contorl its movements as well. What could be the reasons?

I tried the following command:

ros2 launch ros2srrc_irb120_gazebo simulation.launch.py layout:=ros2srrc_irb120_1 endeffector:=RobAlone

ros2 launch ros2srrc_irb120_moveit2 moveit2.launch.py layout:=ros2srrc_irb120_1 endeffector:=RobAlone

These were some of the log messages:

[ERROR] [spawner-7]: process has died [pid 10964, exit code 1, cmd '/opt/ros/humble/lib/controller_manager/spawner egp64_finger_left_controller -c /controller_manager --ros-args'].

I am having the same issue. I suspect a dependency was updated.

Thank you so much! It worked. I got it solved using the method you mentioned. Using the 0.4.6 version of ros-humble-gazebo-ros2-control is the key.
