Detailed Description

Allow moving the control surfaces of a Cessna C-172 plane.

This plugin might be used with other models that have similar control surfaces.

The plugin requires the following parameters: <propeller> Name of the joint controlling the propeller spin. <propeller_max_rpm> Maximum angular speed in rpm. <left_aileron> Name of the joint controlling the left aileron. <left_flap> Name of the joint controlling the left flap. <right_aileron> Name of the joint controlling the right aileron. <right_flap> Name of the joint controlling the right flap. <elevators> Name of the joint controlling the rear elevators. <rudder> Name of the joint controlling the rudder.

The following parameters are optional: <propeller_p_gain> P gain for the PID that controls the propeller's speed. <propeller_i_gain> I gain for the PID that controls the propeller's speed. <propeller_d_gain> D gain for the PID that controls the propeller's speed. <surfaces_p_gain> P gain for the PID that controls the position of the control surfaces. <surfaces_i_gain> I gain for the PID that controls the position of the control surfaces. <surfaces_d_gain> D gain for the PID that controls the position of the control surfaces.

The plugin will be subscribed to the following topic: "~/<model_name>/control" The expected value is a Cessna message.

The plugin will advertise the following topic with the current state: "~/<model_name>/state"

◆ Create()

static TPtr Create	(	const std::string &	_filename,
		const std::string &	_name
	)

inlinestaticinherited

a class method that creates a plugin from a file name.

It locates the shared library and loads it dynamically.

Parameters

[in]	_filename	the path to the shared library.
[in]	_name	short name of the plugin

Returns: Shared Pointer to this class type

References PluginT< T >::filename, gzerr, and SingletonT< SystemPaths >::Instance().

◆ GetFilename()

std::string GetFilename ( ) const

inlineinherited

Get the name of the handler.

References PluginT< T >::filename.

◆ GetHandle()

std::string GetHandle ( ) const

inlineinherited

Get the short name of the handler.

References PluginT< T >::handleName.

◆ GetType()

PluginType GetType ( ) const

inlineinherited

Returns the type of the plugin.

Returns: type of the plugin

References PluginT< T >::type.

◆ Init()

virtual void Init ( )

inlinevirtualinherited

Override this method for custom plugin initialization behavior.

Reimplemented in KeysToCmdVelPlugin, BuoyancyPlugin, HarnessPlugin, FollowerPlugin, PlaneDemoPlugin, MudPlugin, CartDemoPlugin, VehiclePlugin, GimbalSmall2dPlugin, LinearBatteryPlugin, DiffDrivePlugin, and SphereAtlasDemoPlugin.

◆ Load()

virtual void Load	(	physics::ModelPtr	_model,
		sdf::ElementPtr	_sdf
	)

virtual

Load function.

Called when a Plugin is first created, and after the World has been loaded. This function should not be blocking.

Parameters

[in]	_model	Pointer to the Model
[in]	_sdf	Pointer to the SDF element of the plugin.

Implements ModelPlugin.

◆ LoadParam() [1/2]

void LoadParam	(	const sdf::ElementPtr &	_sdf,
		const std::string &	_name,
		V &	_target,
		V	_defaultValue = `V()`
	)		const

inlineprotectedinherited

Load parameter value from _sdf and store it to the given reference, using the supplied default value if the element in _sdf is not found.

A message is written using gzmsg reporting whether the default value was used or not.

Parameters

[in]	_sdf	The SDF element of the plugin.
[in]	_name	Name of a tag inside the SDF.
[out]	_target	The reference to store the param value to.
[in]	_defaultValue	The default value.

References gzmsg, and PluginT< T >::handleName.

◆ LoadParam() [2/2]

void LoadParam	(	sdf::ElementPtr &	_sdf,
		const std::string &	_name,
		std::string &	_target,
		const char *	_defaultValue
	)		const

inlineprotectedinherited

Load parameter value from _sdf and store it to the given reference, using the supplied default value if the element in _sdf is not found.

A message is written using gzmsg reporting whether the default value was used or not. String specialization to allow accepting const char* values for std::string parameters.

Parameters

[in]	_sdf	The SDF element of the plugin.
[in]	_name	Name of a tag inside the SDF.
[out]	_target	The reference to store the param value to.
[in]	_defaultValue	The default value.

◆ Reset()

virtual void Reset ( )

inlinevirtualinherited

Override this method for custom plugin reset behavior.

Reimplemented in KeysToCmdVelPlugin, RandomVelocityPlugin, ElevatorPlugin, FollowerPlugin, LinearBatteryPlugin, ActorPlugin, InitialVelocityPlugin, and SphereAtlasDemoPlugin.
