Hi- I thought the use_database = false tag was working, but now I overlayed all the packages on a pr2 and tried running things and I get the following errors. I made sure cturtle is up-to-date on the robot and rebuilt all the overlaid packages... It's possible that yesterday when I set the tag to false on my other machine it didn't use the database but it still tried opening it, and since the database was there it didn't error. Let me know if there is something else you want me to try! Thanks, --Adam roslaunch pr2_tabletop_manipulation_launch pr2_tabletop_manipulation.launch ... starting nodes and stuff ...
