How can i make pr2 go closer to a wall
Hello, I am trying to let PR2 go parallel with a Wall as close as it can be (hopeful around 5cm).
I tried to change some parameters in globalcostmap, localcostmap and safeteleopbase using rqt_reconfigure since I am not sure which one of them affect the real robot.
i made the inflationradius and even the robot radius to a very small number and I could check from the Rviz that the costmap has changed. However, PR2 stops everytime when the space between the robot and the wall is around 20 cm and i can see there is still space between /safeteleopbase/localcostmap/obstaclelayerfootprint/footprintstamped and the obstacle (wall).
how can i let PR2 go as close as it can be to an obstacle and what parameters should i adjusts?

This seems like a hard problem to me. It took us a long time to get it close to a table. You'd not only need free space currently, but also find a trajectory that is free + obviously remove all safety/padding/etc.

Can you post what the published costmap looks like when you're close to the wall?
