h1. AVBP Mission plugin The _AVBP mission plugin_ is an aircraft plugin, built upon the standard Mission Manager, to supervise adaptive mapping missions. It is defined in the <code class="python">cams_avbp.plugins.mission</code> module. h2. Scenario definition <code class="python">AVBPMission</code> must de declared in the plugins section. The <code class="python">Missions</code> plugin is required and must be included first in the list. Example: <pre><code class="yaml"> aircrafts: 200: replay: false type: 'pprz' plugins: # Other plugins ... - Missions: backup_file: '/PATH/TO/backup_200.bin' Goto: *goto_defaults Segment: *segment_defaults - AVBPMission </code></pre> h2. User remote control You can make remote procedure calls using the http API, that you can issue with a web browser or from the command line with <code class="shell">curl</code>. For instance: <pre><code class="shell"> curl -v "http://127.0.0.1:8000/runtime/call_method/?uav_id=200&plugin=AVBPMission&method=stop" </code></pre> calls the _stop_ method of the uav _200_ defined in the _AVBPMission_ plugin. h2. Event handlers h3. Aircraft status handlers Status messages originated in paparazzi related to the aircraft state and mission execution status. <pre><code class="python"> def flight_param_callback(self, msg): """ Receive pprz FLIGHT_PARAM messages http://docs.paparazziuav.org/latest/paparazzi_messages.html#FLIGHT_PARAM """ pass def engine_status_callback(self, engineStatus): """ Receive pprz ENGINE_STATUS messages http://docs.paparazziuav.org/latest/paparazzi_messages.html#ENGINE_STATUS """ pass def mission_status_callback(self, missionStatus): """ Receive pprz MISSION_STATUS messages http://docs.paparazziuav.org/latest/paparazzi_messages.html#MISSION_STATUS """ pass def nav_status_callback(self, navStatus): """ Receive pprz NAV_STATUS messages http://docs.paparazziuav.org/latest/paparazzi_messages.html#NAV_STATUS """ pass def ap_status_callback(self, apStatus): """ Receive pprz AP_STATUS messages http://docs.paparazziuav.org/latest/paparazzi_messages.html#AP_STATUS """ pass </code></pre> h3. Sensor sample handlers Handler for the internal CAMS event "add_sample". It is called each time a sensor sample is disseminated from another plugin of the same UAV. <pre><code class="python"> def add_sample(self, sample: ty.Union[AbstractSensorSample, SensorSample]): """Catch sensor samples coming from other plugins""" pass </code></pre> h3. Interaction methods These functions are not called periodically by CAMS, but manually by the operators to trigger certain actions. More can be defined provided by <code class="python">__pluginmethods__</code> is update accordingly. <pre><code class="python"> def stop(self): """Disable the AVBPProbe plugin""" pass def pause(self, *args, **kwargs): """Specific stop signal just for the AVBPMission plugin""" pass def play(self, *args, **kwargs): """Specific start signal just for the AVBPMission plugin You can activate this method manually with: curl -v "http://127.0.0.1:8000/runtime/call_method/?uav_id=200&plugin=AVBPMission&method=play or browsing to http://127.0.0.1:8000/rpc (Call UAV plugin method) """ pass </code></pre>
