robot_state_controller

Overview

The robot_state_controller uses the URDF specified by the parameter robot_description and the joint positions from the hardware_interface::JointStateInterface to calculate the forward kinematics of the robot and publish the results via tf, and reads and manages the external incoming tf.

The robot_state_controller package has been tested under ROS Melodic and Noetic on respectively 18.04 and 20.04. This is research code, expect that it changes often and any fitness for a particular purpose is disclaimed.

Hardware interface type

• JointStateInterface Used to get the positions of different joints.
• RobotStateInterface Used to obtain and maintain the transformation relationship of each link of the entire robot.

ROS API

Subscribed Topics

• tf (tf2_msgs/TFMessage)

Obtain and manage maintenance real-time transformation information.

• tf_static(tf2_msgs/TFMessage)

Obtain and manage maintenance static transformation information.

Parameters

• publish_rate (double)

Publish frequency of state publisher, default: 50Hz.

• use_tf_static (bool)

Set whether to use the /tf_static latched static transform broadcaster.Default: true.
