Hi, thanks for your project. I have compiled it successfully, but when I run the launch file and clicked "start planer" in the rviz, the planner can't get an available path. The outputs from terminal are as follow: Screenshot from 2022-04-05 16-49-53

Hello, have you resolved this issue? Currently, my running results also indicate this issue. Can you give me some suggestions？

Hello,

In the above issue, it seems like the tree is not being built properly. Can you visualize the motion primitives tree and send a screenshot? In addition, can you also check if the voxblox map is created properly? If it is not that might be causing the issue.

Best regards, Mihir

Hello, I went to run the MBplanner algorithm again and found that the error is not the same as before, because it was the same error in a certain algorithm before, but it has not been resolved. Sorry.

And now when I run the MBplanner algorithm, it always report errors such as planner is waiting for odometry and waiting for odometry! Then I used the rostopic list to see /velodyne_ Points, using rostopic echo /velodyne_points After checking the points, it was found that there was no data displayed. It should be a problem with the node's publishing and subscription data. I'm not very good at handling it later on. It seems that several algorithms have been adjusted to solve this problem. May I ask how you can solve this problem? I look forward to your valuable suggestions!

I try my best to solves these problems but it is range out of my abilities, and pleases forgive my poor English!
