problem for loading robot pr2 model

Question

Dear All. while I try to Starting the Manipulation Pipeline. I just based on the following website: http://www.ros.org/wiki/pr2_tabletop_manipulation_apps/Tutorials/Starting%20the%20Manipulation%20Pipeline

The step is:

1. rosmake pr2_tabletop_manipulation_launch
2. roscore
3. export ROBOT=sim
4. roscd pr2_tabletop_manipulation_launch
5. modify the pr2_tabletop_manipulation.launch just

-->

Just make it connect as a client for object database running on remote server at Willow Garage 6 cd ~ 7. roslaunch pr2_tabletop_manipulation_launch pr2_tabletop_manipulation.launch The I got the following information: Mainly is said that :

[ERROR] [1329418027.455848865]: Robot model '/robot_description' not found! Did you remap 'robot_description'? [ WARN] [1329418027.463987029]: Models not loaded [FATAL] [1329418027.466372646]: Could not load the xml from parameter server: robot_description

[ERROR] [1329418027.466448443]: Could not load robot model. Are you sure the robot model is on the parameter server?

do I need more step to run this demo? I am using ubuntu 11.04 or 10.04, 64 bit electric ros. The problems are the same. Thanks for any help. Best regards. Zhenli

Answer 2

Answer by myself: I should run pr2 simulator. The steps: 1. roscore 2. export ROBOT=sim 3.roslaunch pr2_gazebo pr2_empty_world.launch 4. Here you also load the object table.cup 5. modify the pr2_tabletop_manipulation.launch just

6. roslaunch pr2_tabletop_manipulation_launch pr2_tabletop_manipulation.launch

Hi zhenli, I also have the same problem and my approach is quite similar to run this demo. I'm using ROS fuerte and Ubuntu LTS 12.04. But I used local database. However, the result gives some errrors and hanging: waitForService: Service [/register_planning_scene] has not been advertised, waiting...
