Actions |
|
======= |
|
|
|
A bunch of action servers for performing basic robocup actions. |
|
|
|
The robocup @work domain is partitioned into 6 basic actions |
|
|
|
- move base |
|
- pick |
|
- perceive |
|
- place |
|
- stage |
|
- unstage |
|
|
|
Each action is implemented as SMACH state machines which are wrapped with |
|
``ActionServer``. An ``ActionClient`` needs to send request using |
|
``GenericExecuteGoal``. |
|
|
|
This request message contains a single dictionary kind of |
|
message called ``parameters`` of type ``diagnostic_msgs/KeyValue[]``. |
|
|
|
.. literalinclude:: ../../../mir_planning/mir_planning_msgs/ros/action/GenericExecute.action |
|
|
|
Each server needs different information from this request message. Please see |
|
the following files for detailed info: |

|
Additionally, :ref:`mir_planner_executor` also sends ``next_action`` as one of the |
|
parameter. This can be used by action servers to have parallel execution of arm |
|
while the base is in motion to save som time. At the moment, only |
|
:ref:`mir_move_base_safe` is using this information. |
|
|
|
This package also contains ``Utils.py`` which contains utility functions for |
|
action servers. |

Usage |
|
----- |
|
|
|
.. code-block:: bash |
|
|
|
roscore |
|
roslaunch mir_actions run_action_servers.launch |
|
|
|
To execute an action, call the corresponding action client with appropriate |
|
arguments. For example, move base safe:: |
|
|
|
rosrun mir_move_base_safe move_base_safe_client_test.py WS01 |
