Hello!, I stay working with the Peter Corke library for robotics and searching methodos to navigate when try to work with the example the next trouble happend.
'path' is not an accessible method of base class 'Navigation'.
Error in Astar/path (line 312)
path@Navigation(as, start);
Error in aestrella (line 8)
as.path(start); % plan solution path start-to-goal, animate
I search in the library, but the method exist if I change in the code 'path' to 'query' the algoritms don't have troubles but isn't make the calculus.
the code example is the next:
load map1 % load map
goal = [50;30];
start=[20;10];
as = Astar(map); % create Navigation object
as.plan(goal,2,3,0); % setup costmap for specified goal;
% standard D* algorithm w/ 2 objectives
% and 3 costmap layers
as.path(start); % plan solution path start-to-goal, animate
P = as.path(start); % plan solution path start-to-goal, return
% path
Can anyone help me?

Try 'query' instead of 'path' as a subclass of navigation.
load map1 % load map
goal = [50;30];
start=[20;10];
as = Astar(map); % create Navigation object
as.plan(goal,2,3,0); % setup costmap for specified goal;
% standard D* algorithm w/ 2 objectives
% and 3 costmap layers
as.path(start); % plan solution path start-to-goal, animate
P = as.path(start); % plan solution path start-to-goal, return
% path
