A simple object follower that finds the closest object in a depth image and commands a differential drive vehicle to move towards the object.
The plugin is essentially an integration of the DiffDrivePlugin and DepthCameraPlugin.

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

◆ Init()
Override this method for custom plugin initialization behavior.
Reimplemented from ModelPlugin.
◆ Load()
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.

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. |

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. |
