robot has the same pick-place motion after changing the object position?

[usut]

Thanks for sharing the code. I want to confirm if the robot has learning in detection and grasping.
I tried to change the positions of the objects. But the robot did not change the pick position, resulting an invalid grasp in the simulation. Is this code just demo for a predefined pick and place movements? If not, I probably need to change more files. Could you tell which files to be changed if the objects position changes? Thanks.

I didn't change anything in the code. I just git clone it to my catkin_ws and then I follow this guide

After I run this code ./pr2_safe_spawner.sh
I just can see the pr2 robot both in gazebo and rviz, but i cannot see the table and item as follwing three picture
Really need help, any advice is appreciate. Need more details on how to run this project
