Hi, thanks for your quesstion :)
Yes, the map-based velocity screening mechanism is implemented in the compute_cost() function in the policy, and policy.gc is modified in the function get_gc() in sarl_star_node(line 172).
Note that in sarl_star_node.py (line 113), we defined a node to subscribe the global costmap published by move_base:
self.global_costmap_sub = rospy.Subscriber('/move_base/global_costmap/costmap', OccupancyGrid, self.get_gc)
which will call the function: get_gc()
That is why we need to launch the move_base before the sarl_star_node in the launch file
Hope this will help!
