Airspeed
========


**Mesure airspeed**


Sensor to compute Airspeed

- https://en.wikipedia.org/wiki/Airspeed

The current implementation is only correct for speed < 1Mach


.. cssclass:: properties morse-section

Configuration parameters for Airspeed
-------------------------------------


You can set these properties in your scripts with ``<component>.properties(<property1>=..., <property2>=...)``.

- ``ComputationMode`` (string, default: ``"Automatic"``)
	Kind of computation, can be one of ['Velocity', 'Position']. Only robot with dynamic and Velocity control can choose Velocity computation. Default choice is Velocity for robot with physics, and Position for others


.. cssclass:: fields morse-section

Data fields
-----------


This sensor exports these datafields at each simulation step:

- ``timestamp`` (float, initial value: ``0.0``)
	number of seconds in simulated time
- ``diff_pressure`` (float, initial value: ``0.0``)
	Diff pressure in Pa

*Interface support:*

(attention, no interface support!)

.. cssclass:: services morse-section

Services for Airspeed
---------------------

- ``get_properties()`` (blocking)
    Returns the properties of a component.
    
    
  - Return value

    a dictionary of the current component's properties  

- ``get_local_data()`` (blocking)
    Returns the current data stored in the sensor.
    
    
  - Return value

    a dictionary of the current sensor's data 

- ``set_property(prop_name, prop_val)`` (blocking)
    Modify one property on a component
    
    
  - Parameters

    - ``prop_name``: the name of the property to modify (as shown the documentation)
    - ``prop_val``: the new value of the property. Note that there is no checking about the type of the value so be careful

  - Return value

    nothing 

- ``get_configurations()`` (blocking)
    Returns the configurations of a component (parsed from the properties).
    
    
  - Return value

    a dictionary of the current component's configurations  



.. cssclass:: examples morse-section

Examples
--------


The following examples show how to use this component in a *Builder* script:

.. code-block:: python


    from morse.builder import *
    
    # adds a default robot (the MORSE mascott!)
    robot = Morsy()
    
    # creates a new instance of the sensor
    airspeed = Airspeed()

    # place your component at the correct location
    airspeed.translate(<x>, <y>, <z>)
    airspeed.rotate(<rx>, <ry>, <rz>)
    
    robot.append(airspeed)
    
    # define one or several communication interface, like 'socket'
    airspeed.add_interface(<interface>)

    env = Environment('empty')
