I removed the portion of your question in which you ask for contact information as it goes against the purpose of this site (an open, public forum which benefits everyone) and the portion stating your deadline as it's considered bad form.

Can you please update your question with some more information. For example, what do you mean by

it goes somewhere and it crashes

? The node crashes, the robot crashes into physical objects like a wall? How are you giving it a destination? Please include anything else that may be helpful too.

@jayess first i will launch the gazebo model then the amcl (with map) then the move base and gives the 2_d nav goal in rviz then robot goes to random positions and doesnt stop moving the global planner and local planner shows the right path ,but robot doesn't move i am using my own urdf and amcl,move, gmapping,configuration files all from the husk_bot navigation
