This package contains the description of the PR2 robot. It supercedes the older pr2_defs package which was written for the alpha hardware.

Package organization

This package contains robot description files for PR2, organized into subdirectories as follows:

  • urdf/ contains (xacro representations of) urdf descriptions of various parts of the PR2 (arm, torso, etc.).

  • robots/ contains (xacro representations of) urdf descriptions of the full robot, that refer to the macros in urdf/

  • gazebo/ contains (xacro representations of) urdf descriptions of simulated PR2 components, like the simulated battery controller.

  • meshes/ contains mesh files (.stl,.dae) for visualization and collision properties.

Changes from Alpha URDFs

Some notable changes from pr2_defs:

  • updated frame_id: base_laserbase_laser_link (consistent with tilt_laser_link)

  • new frame_id: {narrow,wide}_stereo_{l,r}_stereo_camera_optical_frame

  • removed frame: plug_holder (might need to add back for plug_in_gazebo to work)

PR2 Coordinate Frames

To see the PR2 URDF graphically, you can1

rosrun xacro xacro.py `rospack find pr2_description`/robots/pr2.urdf.xacro > pr2.urdf
rosrun urdf urdf_to_graphiz pr2.urdf
evince pr2.pdf

A snapshot (r46956) is attached here for reference.

In general, PR2 URDF contains a tree structured set of links and joints, with base_footprint as the root link of the tree.

Working with a Kinect

To use the original Kinect with the PR2 (either robot or simulation), set the KINECT1 environment variable to true.

export KINECT1=true

To use a Kinect2 with the PR2 (either robot or simulation), set the KINECT2 environment variable to true.

export KINECT2=true

If both variables are set, the Kinect 2 will take precedence over the original Kinect.

  1. Starting with Electric Turtle, check_urdf and urdf_to_graphiz has been moved from urdf into urdf_parser (1)
