Checks if any obstacles in the costmap lie inside a convex footprint that is rasterized into the grid.
- Parameters:
-
position The position of the robot in world coordinates footprint The specification of the footprint of the robot in world coordinates inscribed_radius The radius of the inscribed circle of the robot circumscribed_radius The radius of the circumscribed circle of the robot
- Returns:
- Positive if all the points lie outside the footprint, negative otherwise
Implements base_local_planner::WorldModel.

| int | y1 | ||
| ) | [private] |
Rasterizes a line in the costmap grid and checks for collisions.
- Parameters:
-
x0 The x position of the first cell in grid coordinates y0 The y position of the first cell in grid coordinates x1 The x position of the second cell in grid coordinates y1 The y position of the second cell in grid coordinates
- Returns:
- A positive cost for a legal line... negative otherwise
