Detailed Description

Multi interface forward command controller for a set of interfaces.

This class forwards the command signal down to a set of interfaces on the specified joint.

Parameters

joint	Name of the joint to control.
interface_names	Names of the interfaces to command.

Subscribes to:

commands (std_msgs::msg::Float64MultiArray) : The commands to apply.

Member Function Documentation

◆ declare_parameters()

void forward_command_controller::MultiInterfaceForwardCommandController::declare_parameters ( )

overrideprotectedvirtual

Derived controllers have to declare parameters in this method. Error handling does not have to be done. It is done in on_init-method of this class.

Implements forward_command_controller::ForwardControllersBase.

◆ read_parameters()

controller_interface::CallbackReturn forward_command_controller::MultiInterfaceForwardCommandController::read_parameters ( )

overrideprotectedvirtual

Derived controllers have to read parameters in this method and set command_interface_types_ variable. The variable is then used to propagate the command interface configuration to controller manager. The method is called from on_configure-method of this class.

It is expected that error handling of exceptions is done.

Returns: controller_interface::CallbackReturn::SUCCESS if parameters are successfully read and their values are allowed, controller_interface::CallbackReturn::ERROR otherwise.

Implements forward_command_controller::ForwardControllersBase.
