Hi! (PS: If this is showing up as a response on another question, please make it as a new post.)
I have nearly any Labview-
or programming experience, and got trouble trying to plan a path for our
autonomous mobile robot.
We based our program on an already existing example on AD* path planning.
This example was found in NI Example finder: Robotics/path planning/Anytime D
Star on an occupancy grid.
We deleted the part outside the first while-loop, and replaced it with a
self-created defined map.
After the
object-coordinates have been defined, AD* seems to respond differently
depending on where the start and/or goal positions are placed relative to the
defined object.
Sometimes AD* doesn't plan
any path at all, and path cost equals 0 at all times.
If the path runs through a
defined obstacle, AD* runs until it stops somewhere near the object, giving the
message "No path exists through the obsticles". Sometimes it just
stoppes, without giving this message.
Is this caused by the
"no valid path exists"-output on the AD*-VI, or is it something wrong
with the map? And is it possible to make the VI another way, so that the
algorithm plans a path around the object rather than giving this message?
Hoping for answers 🙂
