I’m at the last part of unit 7 trying to send an action goal:
ros2 action send_goal /gripper_controller/gripper_cmd control_msgs/action/GripperCommand "command:
position: 0.03
max_effort: 0.0
"
but I keep getting The passed action type is invalid
I verified that the action and interface looks correct:
Am I missing something?
You are using the “Message” definition instead of the “Action” definition.
Sorry, could you elaborate a little bit more? This is the instruction command for us to use, and I’m just copying it exactly.
ros2 action send_goal /gripper_controller/gripper_cmd control_msgs/action/GripperCommand "command:
position: 0.03
max_effort: 0.0
"
Weird, I tried the exact same command (copied and paste) and it works today.
