Detailed Description

IRI ROS Specific Driver Class.

This class inherits from the IRI Base class IriBaseDriver, which provides the guidelines to implement any specific driver. The IriBaseDriver class offers an easy framework to integrate functional drivers implemented in C++ with the ROS driver structure. ROS driver_base state transitions are already managed by IriBaseDriver.

The DynamixelNoGripperDriver class must implement all specific driver requirements to safetely open, close, run and stop the driver at any time. It also must guarantee an accessible interface for all driver's parameters.

The DynamixelNoGripperConfig.cfg needs to be filled up with those parameters suitable to be changed dynamically by the ROS dyanmic reconfigure application. The implementation of the CIriNode class will manage those parameters through methods like postNodeOpenHook() and reconfigureNodeHook().

Member Typedef Documentation

typedef iri_dynamixel_no_gripper::DynamixelNoGripperConfig DynamixelNoGripperDriver::Config

define config type

Define a Config type with the DynamixelNoGripperConfig. All driver implementations will then use the same variable type Config.

Definition at line 71 of file dynamixel_no_gripper_driver.h.

Constructor & Destructor Documentation

DynamixelNoGripperDriver::DynamixelNoGripperDriver ( void )

constructor

In this constructor parameters related to the specific driver can be initalized. Those parameters can be also set in the openDriver() function. Attributes from the main node driver class IriBaseDriver such as loop_rate, may be also overload here.

Definition at line 10 of file dynamixel_no_gripper_driver.cpp.

DynamixelNoGripperDriver::~DynamixelNoGripperDriver ( void )

Destructor.

This destructor is called when the object is about to be destroyed.

Definition at line 19 of file dynamixel_no_gripper_driver.cpp.

Member Function Documentation

bool DynamixelNoGripperDriver::close_gripper ( )

gripper will perform a closing action (pick)

Definition at line 125 of file dynamixel_no_gripper_driver.cpp.

bool DynamixelNoGripperDriver::closeDriver ( void ) [virtual]

close driver

In this function, the driver must be closed. Variables related to the driver state must also be taken into account. This function is automatically called by IriBaseDriver::doClose(), an state transition is performed if return value equals true.

Returns:: bool successful

Implements iri_base_driver::IriBaseDriver.

Definition at line 68 of file dynamixel_no_gripper_driver.cpp.

void DynamixelNoGripperDriver::config_update	(	Config &	new_cfg,
		uint32_t	level = `0`
	)

config update

In this function the driver parameters must be updated with the input config variable. Then the new configuration state will be stored in the Config attribute.

Parameters:

new_cfg	the new driver configuration state
level	level in which the update is taken place

Definition at line 83 of file dynamixel_no_gripper_driver.cpp.

void DynamixelNoGripperDriver::disable_gripper ( )

disables the gripper

Definition at line 166 of file dynamixel_no_gripper_driver.cpp.

float DynamixelNoGripperDriver::get_current_angle ( )

returns current angle position of the motor

Definition at line 150 of file dynamixel_no_gripper_driver.cpp.

float DynamixelNoGripperDriver::get_current_effort ( )

return the current motor effort

Definition at line 145 of file dynamixel_no_gripper_driver.cpp.

bool DynamixelNoGripperDriver::is_at_max_angle ( )

returns true if the motor is at the maximum angle

Definition at line 155 of file dynamixel_no_gripper_driver.cpp.

bool DynamixelNoGripperDriver::is_at_min_angle ( )

returns true if the motor is at the minimum angle

Definition at line 161 of file dynamixel_no_gripper_driver.cpp.

bool DynamixelNoGripperDriver::move_gripper ( const double position_in_radians ) [private]

internal function to perfemor gripper movement

bool DynamixelNoGripperDriver::open_gripper ( void )

gripper will perform an opening action (lift)

Definition at line 120 of file dynamixel_no_gripper_driver.cpp.

bool DynamixelNoGripperDriver::openDriver ( void ) [virtual]

open driver

In this function, the driver must be openned. Openning errors must be taken into account. This function is automatically called by IriBaseDriver::doOpen(), an state transition is performed if return value equals true.

Returns:: bool successful

Implements iri_base_driver::IriBaseDriver.

Definition at line 45 of file dynamixel_no_gripper_driver.cpp.

void DynamixelNoGripperDriver::scan_XML_files ( void )

Scan for correct configuration xml files.

Definition at line 23 of file dynamixel_no_gripper_driver.cpp.

bool DynamixelNoGripperDriver::startDriver ( void ) [virtual]

start driver

After this function, the driver and its thread will be started. The driver and related variables should be properly setup. This function is automatically called by IriBaseDriver::doStart(), an state transition is performed if return value equals true.

Returns:: bool successful

Implements iri_base_driver::IriBaseDriver.

Definition at line 73 of file dynamixel_no_gripper_driver.cpp.

void DynamixelNoGripperDriver::stop_gripper ( )

ask gripper to stops its motion

Definition at line 130 of file dynamixel_no_gripper_driver.cpp.

bool DynamixelNoGripperDriver::stopDriver ( void ) [virtual]

stop driver

After this function, the driver's thread will stop its execution. The driver and related variables should be properly setup. This function is automatically called by IriBaseDriver::doStop(), an state transition is performed if return value equals true.
