we have used a single lidar with slam-gmapping but now we want to extend this with multiple lidars (around 4 sick lidars). is there anyway to maybe merge the data together and continue using slam-gmapping (as ive read AMCL can subscribe to two LaserScan topics and combine it into one topic but would this be feasible).

otherwise is it advisable to have a gmapping node for each lidar and then combine the costmap created

Or alternatively use octomap to input all the data to one map and create a cost map

what would be the best approach?

Hi i would like to know the the difference between gazebo and v-rep for simulation and the pros and cons of each if possible

how do i make the global planner realize that its path is blocked by an obstacle and re-update faster ?

Hi i am using a 2d lidar tilted at an angle such that it hits the ground and we are also using a mono-cam for detection of objects (static etc) . Is there any way that i can fuse these two reading i.e the lidar readings onto the camera readings so that i can measure the dist of object through this fuse data(width and x,y positions of the boundaries)

correct me if im wrong . but is the obtacle.cpp file for obstacle msgs for dynamic obstacles

I need to be able to switch between two planners based at runtime based on some logic devised.

How exactly do i do this if both are ros nodes? (Is it possible to do this even if these nodes are not registered as planners)

setup local planner with 3d lidar Hi I would like to know if it is possible to use a 3d Lidar with the Navigation stack

What exactly is the difference between teb and eband local planner and how exactly do they work differently ?

We are currently using teb_local_planner bit it doesn't work for dynamic obstacles in the bots path... in th cost map a dynamic obstacle is perceived as a wall ...i think . Is there any other local planner which can be used for moving around dynamic obstacles??thanks

Hi have you been able to implement switching global planners at runtime?
