EBand cannot avoid dynamically added obstacles in any path (global/local)

[vmoysiadis]

Good evening people and thanks for that stable planner.
everything is working fine except the dynamically avoidance of an obstacle

what i do:
Scenario 1)
*Using DWA for global planner and Eband for local planner
Scenario 2)
*Using Eband for both global and local planner

i give a goal to the robot via rviz.Robot start moving smoothly.
i add an obstacle via gazebo,on the global planner green line.
i get warnings:

Calculation of Distance between bubble and nearest obstacle failed. Frame 24 of 203 in collision. Plan invalid
[ WARN] [1500970819.269624973, 141.404900000]: Conversion from plan to elastic band failed. Plan probably not collision free. Plan not set for optimization
[ WARN] [1500970819.670180554, 141.805300000]: Optimization failed - Band invalid - No controls availlable

robot is moving forward like there is no obstacle

any ideas ?
thanks in advance

Hi everyone , I am also facing problem with Eband using dynamic obstacle. There had some discussion previously between @vmoisiadis and @marine0131 regarding the same. Guys can you help in dealing with dynamic obstacle for scenario Eband as local plan and DWA as global plan as I am also getting the warning as :
Calculation of Distance between bubble and nearest obstacle failed. Frame 24 of 203 in collision. Plan invalid
[ WARN] [1500970819.269624973, 141.404900000]: Conversion from plan to elastic band failed. Plan probably not collision free. Plan not set for optimization
[ WARN] [1500970819.670180554, 141.805300000]: Optimization failed - Band invalid - No controls availlable

Thanks in advance !
