Struct to create truck and a dock object and simulate with keyboard arrows.
truck.m: Handle object that simulates a truck with a cabin and a truck.
dock.m: Handle object that simulates a dock.
logic.m: Creates a fuzzy logic control for this problem (see the file for more information of how to use other fuzzy files)
Example:
d = dock([17,50],0);
d.minDistance = 3;
d.minOrientation = 45;
t = truck(d.position+[20 0]);
t.supressWarnings = 1;
h = t.plot('','','','hold');
d.plot(h,'','plotPoint','hold');
while ishandle(h) && ~strcmp(t.lastPressedKey, 'escape')
t.move; % this enables user to control the truck with keyboard arrows (spacebar resets steering)
h = t.plot('next','b','','hold');
if d.docked(t,'message'), break, end
pause(.001);
end
See html file for more help.
See example_simulation.m for more examples that uses fuzzy logic control.
