Steer Drive Controller

Controller for a steer drive mobile base.

仕様

  • Subscribe
    • steer_drive_controller/cmd_vel にTwist型のメッセージを投げて下さい.
  • Publish

    • steer_drive_controller/odom を出すべきなのですが,未完成です.
  • 例:SteerDriveController + SteerBot(RobotHWSim) で起動して,以下のメッセージで動く

rostopic pub -1 steer_drive_controller/cmd_vel geometry_msgs/Twist -- '[1.0, 0.0, 0.0]' '[0.0, 0.0, 0.5]'

ベース

  • base_link

ステアリング

  • steer

ホイール

  • left_front_wheel
  • left_rear_wheel
  • right_front_wheel
  • right_rear_wheel

センサ

  • camera_link
  • front_bottom_lrf
  • front_top_lrf
  • rear_bottom_lrf

third_robotのjointメモ

ホイール

  • base_to_left_front_wheel
  • base_to_left_rear_wheel
  • base_to_right_front_wheel
  • base_to_right_rear_wheel

ステアリング

  • base_to_steer
  • base_to_steer_right: gazebo用のvirtual.
  • base_to_steer_left: gazebo用のvirtual.

デバッグ開発の手順

準備

  • パスを通す
source path.bash

  • gazeboを実行する
roslaunch third_robot_gazebo third_robot_world.launch 

  • コントローラ動作用の最低限の設定を行うlaunchファイルを実行する
roslaunch steer_drive_controller steer_drive_test_setting.launch 

デバッガ

  • パスを通したコンソールでQtCreatorを起動する
qtcreator

  • QtCreatorでROSのパッケージをビルド&デバッグ実行するにしたがってビルドする.実行オプションでsteer_drive_testを選択する.

  • third_robot_control/steer_drive_controller/include/steer_drive_controller.h内で#define GUI_DEBUGをアンコメントアウトする.

    • 53行目:#define GUI_DEBUG // uncommentout when you use qtcreator for debugging ってとこ.
    • デバッグ用のモジュールに名前空間がついてないので,無理やり付与する設定.
  • third_robot_control/steer_drive_controller/test/steer_drive_test.cpp のmain関数内でブレイクポイントを置いてデバッグ実行.

    • SteerRobotはフェイクで作ってある.
    • bool rt_code = rb_controller.init(steer_drive_bot, nh_main, nh_control); でコントローラの初期化
CHANGELOG

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Changelog for package steer_drive_controller ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

0.1.0 (2016-12-28)

  • steer_drive_controller: New controller for steering mechanism drive systems.
  • This controller was built up from an existing controller, diff_drive_controller.
  • Control is in the form of a velocity command, that is split then sent on the single wheel joint and single steer joint.
  • Odometry is published to tf and to a dedicated nav__msgs/Odometry topic.
  • Realtime-safe implementation.
  • Implements task-space velocity, acceleration and jerk limits.
  • Automatic stop after command time-out.
  • Contributors: Masaru Morita.
