2015-03-11 00:54:34 -0500 asked a question Which robot will be good for table top manipulation?

I do not have any experience in working with PR2. However, I want to do table top manipulation using PR2 in ros/gazebo. I want to know the hand capability of PR2. Can PR2 work with thin object (for example thin small wooden plate)?
Which robot do you think will be good for this kind of work? I am using ros hydro and LTS ubuntu 12.04. Thank you.

2015-03-10 02:31:15 -0500 asked a question creating my own objects in gazebo

I want to do pick and place operation using a robot (for example PR2)in ros/gazebo. It requires point cloud processing in PCl to detect objects and position them. However, the environment with specific objects are real. How to create my own object models on a table top so that the simulated robot can work with those objects? Anyone can please help about how to do this?

Thank you. I followed all basic tutorials here. However I just got stuck at pcl/pointcloud stuff. I am facing problem in creating a node subscribing to kinect data. Can somebody point the direction to achieve this?

I also want to do the same. Can you please give some examples/tutorials that would be helpful to proceed? Thank you
