ROS API

gazebo_ros_power_node

Gazebo plugin for simulating the PR2 power monitor.

Subscribed Topics

plugged_in (pr2_gazebo_plugins/PlugCommand)
  • plugged in state

Published Topics

<powerStateTopic> (pr2_msgs/PowerState)
  • simulated power state

gazebo_ros_prosilica_node

Gazebo plugin for simulating the prosilica camera. This follows the standard ROS API for camera drivers.

Published Topics

<imageTopicName> (sensor_msgs/Image)
  • Camera image
<cameraInfoTopicName> (sensor_msgs/CameraInfo)
  • Camera info

Services

request_image (polled_camera/GetPolledImage)
  • (Polled Mode Only) Captures an image and publishes it in the namespace specified by the request message. Returns the timestamp.

gazebo_ros_controller_manager

GazeboRosControllerManager plugin provides similar ROS interface as pr2_etherCAT on the physical PR2 robot. This plugin is written in a way that PR2 controller manager works transparently with either this simulated plugin or the pr2_etherCAT hardware. For more information on using generic controllers or PR2 specific controllers with this plugin, please see pr2_controller_manager.

Tutorials

Roadmap

This stack will be updated with new features as the PR2 hardware itself is updated. Future versions will also incorporate dynamic_reconfigure options to match ORS driver functionality.
