Detailed Description

Forward command controller for a set of joints.

This class forwards the command signal down to a set of joints on the specified interface.

Parameters

joints	Names of the joints to control.
interface_name	Name of the interface to command.

Subscribes to:

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

Member Function Documentation

◆ declare_parameters()

void forward_command_controller::ForwardCommandController::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::ForwardCommandController::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.

The documentation for this class was generated from the following files:
