Package Description

hrpsys_gazebo_general

This package consists iob.cpp which is low-level interface of RobotHardware on hrpsys and IOBPlugin.cpp which is gazebo plugin to comunicate with iob.cpp.

Environment variables used in iob.cpp

• HRPSYS_GAZEBO_IOB_NAME
  • ROS node name of hrpsys(RobotHardware) node. (default: "hrpsys_gazebo_iob")
• HRPSYS_GAZEBO_CONFIGURATION
  • ROS namespace of configuration parameters. (default: "hrpsys_gazebo_configuration")
• HRPSYS_GAZEBO_ROBOTNAME
  • Robot Name
• HRPSYS_GAZEBO_IOB_SYNCHRONIZED
  • Synchronized mode between hrpsys step and gazebo step. (default: false)
• HRPSYS_GAZEBO_IOB_SUBSTEPS
  • Number of substeps. Controlling command will be sent in every substeps. (default: 1)

hrpsys_gazebo_tutorials

This package is a collection of examples for using hrpsys_gazebo system and utility scripts.

• You should prepare robot model file. Supported types of model file are collada(openrave) and VRML(openhrp3). URDF and OpenRAVE xml can be used by converting to collada.
  • <robot_name>.yaml for configurating gazebo setting and hrpsys setting
  • (automatically generated) <robot_name>.urdf under robot_models/<robot_name> directory
  • (automatically generated) hrpsys settings (you should have a collada or VRML robot model file)
  • <robot_name>_optional_urdf_setting.sh under robot_models/<robot_name> directory, this is for adding description used by gazebo (such as sensor settings, collision and friction setting)

Setting of <robot_name>.yaml files

This is yaml file for configuring gazebo setting.

# top level name space()

  use_velocity_feedback: true
# synchronized hrpsys and gazebo

(automatically generated files)

You can use robot_models/install_robot_common.sh for installing urdf model file. This scripts converts collada file in hrpsys_ros_bridge_tutorials/models directory to urdf file.
