2012-11-19 12:28:19 -0500 asked a question The SetJointPositions function is not working in Gazebo 1.2 ?!!

Hi all,

I am trying to use setmodelconfigurations to move the joints arbitrarily in Gazebo 1.20. The problem is that when I set the configuration, the model didn't move at all! I look inside the codes of setModelCofiguration and found that the SetJointPositions function is probably not working. Did anyone notice this problem or I did something wrong? Any suggestions? Thank you!

2012-11-19 08:22:43 -0500 answered a question gazebo plugin undefined symbol

Figured it out... I forgot to uncomment the definition of spawngazebomodel function. I think that the problem is I declared the function but didn't define it. So the library cannot actually use it.

Hi all,

I am trying to make a gazebo plugin work now. The plugin compiles just fine but when I run it, it gives the the following errors: undefined symbol: _ZN6gazebo18GazeboRosApiPlugin16spawnGazeboModelERN11gazebo_msgs18SpawnModelRequest_ISaIvEEERNS1_19SpawnModelResponse_IS3_EE

Does anyone know what causes the problem? Thank you!!

2012-11-19 04:25:32 -0500 asked a question Adding dependencies in cmake

Hi all,

I am trying to compile a package using cmake now. It is not a ros package but it depends on some of ros packages. The way I am compiling it is, make a dir called build in the source code directory and then use cmake .. to generate all the files for compiling. Because I don't know where to set the dependencies as we usually do in manifest.xml, it keeps give me the error of unable to find the header files. Does anyone know where I should edit so that I can add the dependencies in? Thank you!

Hi all,

I am trying to use Graspit! in ros. But I couldn't launch Graspit! with plugins. I have tried rosrun graspit graspit plugin: and it didn't work. Does anyone have experience with running Graspit! with plugins? Thank you very very much!

2012-11-06 03:16:56 -0500 answered a question Got IK error 33 after generating IK solver using planning description configuration wizard

Hi, thank you for the reply. I just tried it in an empty gazebo world. So there should not be objects in collision. The arm is 6 dofs plus a four fingers hand. So I have four groups. Do you think that the groups may collide? Otherwise do you know where I can check where the collisions come from? Thank you!

2012-11-05 17:17:59 -0500 asked a question Got IK error 33 after generating IK solver using planning description configuration wizard

Hi All,

I recently generated the ik solver for my own 6 dofs robot arm using planning description configuration wizard. But when I tried to calculate the ik solution for a definitely feasible pose, I got the error code 33. I checked the rxconsole and it says that ik initial checking fails. Does anyone know what causes the problem? Thank you!

Some follow up information, I found there is a topic called r_gripper_l_finger_force_ground_truth. But the topic just keeps giving me zeros. Does anyone know if this topic is the right one? thanks.

2012-10-17 06:55:41 -0500 asked a question pr2 gripper sensor in gazebo?

Hi all,

I am trying to get tactile sensor or fingertip pressure sensor data from pr2 in simulation. It seems that there is no topic publishing this kind of data. Does anyone know where I can get the sensor data for pr2's gripper? Thank you!
