Unable to Call start_traj_mode Service

[Saketh7256]

Hello,

I am experiencing a challenge with the MotoROS2 system while trying to activate trajectory mode on my robot. Initially, I received the following error message:

To resolve this, I attempted to activate the trajectory mode using the start_traj_mode service with these commands:

1.ros2 service call /start_traj_mode motoros2_interfaces/srv/StartTrajMode &
2.ros2 service call /start_traj_mode motoros2_interfaces/srv/StartTrajMode "{}"

However, both attempts returned an error stating that "The passed service type is invalid." I confirmed the availability of the /start_traj_mode service using ros2 service list, which shows the service as available.

Could you assist me
Thank you for your support!

It's possible you forgot to source /path/to/your/colcon_ws/install/setup.bash before trying to ros2 service call the service.

Could I again ask you to please post your questions about MotoROS2 on the MotoROS2 Discussion forum? Thank you.

@Saketh7256: have you been able to resolve your issue?

Through a separate email chain, I can report that he was able to move the robot via the python script. I believe the solution involved sourcing the appropriate workspace(s).

The current issue is regarding MoveIt. I advised him to open a ticket on the MoveIt discussion forum.
