Cannot reset robot position in stage_ros #3

Closed heleidsn closed 4 years ago

heleidsn commented 4 years ago

Hi, I am very interested in this work and thank you very much for open source the code. I want to repeat the experiment. But I find two problems:

  1. I cannot reset the robot position: https://github.com/ethz-asl/rl-navigation/blob/a1831d85c5ec3f6c76c4d9ed243cfd4b04407168/scripts/train_cpo.py#L156 It doesn't work.

  2. I cannot receive the stalled message: https://github.com/ethz-asl/rl-navigation/blob/a1831d85c5ec3f6c76c4d9ed243cfd4b04407168/scripts/environments/base_environment.py#L155

I used the Stage-ros simulator branch with add_pose_sub enabled as mentioned in Readme. I guess it is because of this stage_ros branch is not up to date.

Did you do some modification on the stage_ros code? Where can I get the lasted stage_ros code which can set position?

Looking for your reply! Thank you.

Hello, I ran the code but met a problem. The problem is that the loaded robot model can't run within the map. I guess it's caused by that the coordinate system's origin of /odom and /map is mismatching, however I can't solve it. image

Can you help me? Looking forward to your reply. Thanks.
