Hello, where can I see the length of this path in the code?
use python3.8
The following prompt appears when running arastar.py
ModuleNotFoundError: No module named 'Search_based_Planning'
thank you
In some case, there would be no path extrated right!
rrt_star.py :
this part of code
def find_near_neighbor(self, node_new):
n = len(self.vertex) + 1
r = min(self.search_radius * math.sqrt((math.log(n) / n)), self.step_len)
dist_table = [math.hypot(nd.x - node_new.x, nd.y - node_new.y) for nd in self.vertex]
dist_table_index = [ind for ind in range(len(dist_table)) if dist_table[ind] <= r and
not self.utils.is_collision(node_new, self.vertex[ind])]
return dist_table_index
r is the search radius to search for potential best parent nodes,but I don‘t think it should use min() function. I guess the function of the code about r is that as the vertex increases, the radius of the search for the parent node also increases. But it should use max() function. Maybe there is something I misunderstood, but using max() works better works more in principle..
Is it my understanding of your code is wrong, I hope to get your help.
hello how to run it?
It's nice to see the algorithms implemented. Can you also include an overview paper to describe the basic ideas and differences of the algorithms?
Can you please implement JPS(Jump point search) under Path Finding Algorithms?
which tool is required to run these codes
Could you have a matlab version, thank you very much.

Hello, how to find the actual path length of rrt_star algorithm
![road](https://user-images.githubusercontent.com/42332058/157599499-7cd79207-4150-4f6c-991e-4600a74487d
hello,when i use a star,change the goal point,but it can't get the result,can u give me some sdvice ,i will be appreciated
Hello,
Nice work to combine several robot motion planners and open source a package!
I have some questions:
Thanks a lot for your advice and thoughts!
Best,
Bryan
self.motions = [(-1, 0), (-1, 1), (0, 1), (1, 1),
(1, 0), (1, -1), (0, -1), (-1, -1)]
What does that mean???thanks
I'm doing some stuff that dynamic rrt 2D will fit perfectly. But I'm having a really hard time understand the code. I know the basics of RRT and RRT* but the code still confusing.
def find_near_neighbor(self, node_new):
n = len(self.vertex) + 1
r = min(self.search_radius * math.sqrt((math.log(n) / n)), self.step_len)
dist_table = [math.hypot(nd.x - node_new.x, nd.y - node_new.y) for nd in self.vertex]
dist_table_index = [ind for ind in range(len(dist_table)) if dist_table[ind] <= r and
not self.utils.is_collision(node_new, self.vertex[ind])]
return dist_table_index
Is this n plus 1 in the code correct?
how to draw these gif?
Hello, after I run the D* algorithm, the mouse click on the picture does not produce the effect of generating obstacles. I want to achieve the dynamic picture effect you showed, what should I do?For example, if I click on a certain area in the picture, an obstacle will be created, and the path will also change as the obstacle appears.
the file dynamic_rrt.py
is actually static rrt algo
How do you install Sampling based Planning as a library?
I tried using smbclient to load PyTorch model weights from a server, but I encountered some issues.
file_path = r"\\x.x.x.x\home\pytorch-models\resnet18-f37072fd.pth"
with smbclient.open_file(file_path, mode='rb', buffering=0) as fd:
data = torch.load(fd, map_location=torch.device('cpu'))
The error
Exception has occurred: RuntimeError
PytorchStreamReader failed reading file data/140219036705280: file read failed
Is there any way I can load model weights?
if np.random.random() > goal_sample_rate:
return Node((np.random.uniform(self.x_range[0] + delta, self.x_range[1] - delta),
np.random.uniform(self.y_range[0] + delta, self.y_range[1] - delta)))
return self.s_goal
why np.random.random() > goal_sample_rate:???and if not why return self.s_goal???
Hi,
When I run the rrt3D.py, it occured a mistake:
Original exception was: Traceback (most recent call last): File "/home/xia/mydemo01_ws/src/PathPlanning-master/Sampling_based_Planning/rrt_3D/utils3D.py", line 410, in <module> A.run() File "/home/xia/mydemo01_ws/src/PathPlanning-master/Sampling_based_Planning/rrt_3D/utils3D.py", line 403, in run visualization(self) File "/home/xia/mydemo01_ws/src/PathPlanning-master/Sampling_based_Planning/rrt_3D/../../Sampling_based_Planning/rrt_3D/plot_util3D.py", line 96, in visualization for i in initparams.Parent: AttributeError: 'rrt_demo' object has no attribute 'Parent'
What should I do next?
Hello,
such a nice repository benefits me a lot and so kind of you to make it open source!
Question
There’s some possible legal issues on the license of your repository when you combine numerous third-party packages.
For instance, matplotlib, scipy, numpy and random you imported are licensed with Python Software Foundation License (PSF), BSD License, BSD License and Python Software Foundation License, respectively.
However, the MIT license of your repository are less strict than above package licenses, which has violated the whole license compatibility in your repository and may bring legal and financial risks.
Advice
You can select another proper license for your repository, or write a custom license with license exception if some license terms couldn’t be summed up consistently.
Best wishes!
Hello, do you have any information about these algorithms?
In line 54 there is a minor mistake.
There is must be
if dist <= self.step_len and not self.utils.is_collision(node_new, self.s_goal):
instead
if dist <= self.step_len:
because otherwise, if there is obstacle in a dist, than the last node will be connected trought it.
I tried to change the search space dimensions and obstacles but it is not being implemented when i execute the code. The same search space and obstacles set by you appears instead. Please help as I need to test the algorithms to suit them to my need.
为什么在一些场景(简单)中会出现死循环和parent没找到坐标的情况
May I ask if there is more detailed code explanation for A* ? I got some do not understand as a beginner.
I downloaded the entire zip and unzipped it in PyCharm. When I tried bfs for testing, everything went well until plot.animation(path,visited,"Breadth-first Search (BFS)")
Then I created a breakpoint and found the statement that stops the program. It is plt.plot(self.xI[0], self.xI[1], "bs")
in def plot_grid(self, name) :
In Search_based_Planning/Search_2D/plotting.py
.
There may be something I didn't realize, but can you give a solution or some help? thanks : )
my environment is as follows:
By the way, queue.py
is best renamed to something like diy_queue.py
, and queue.py
will cause problems AttributeError: module'queue' has no attribute'queue'
I am wonderring how do u make the gifs~
Hi zhm-real:
In astart, you build a priority queue.However, it will have repetition point when update the f value of a point.
I would like to know that how to avoid this situation or something i miss that you have already avioded this situation.`
