Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. move ( goal) i += 1 Definition at line 999 of file move_base.cpp. Prepare the subscriber before the loop and use spinOnce in the loop. A robot using move base sequence can have two states: paused: paused state stops the move base server and stops the sequence server so the robot stays at its place. For comments see Section 4. # Waits for the server to finish performing the action. Assassin- if successfully damages opponent they only have 1 action until healed. Subject: Bug#896413: fixed in ros >-geometry2 0. To avoid leaving the user wondering whats happening and if all is going as desired, Actions implement a feedback mechanism, which let the user receive information every now and then. The whole node code without comments is provided in Section 3. Definition at line 273 of file move_base.cpp. # ===== DO NOT MODIFY! It can also be sued to pass precalculated set of goals all at once by publishing on it.. the topic that is used to append new goals to the goals sequence. The move_base node links together a global and local planner to accomplish its global navigation task. My problem is that I can't get a subscriber and move_base Action API to work simultaneously.
