udacity / carnd-path-planning-project Goto Github PK

In order for Udacity CarND students to be able to write unit-tests for their C++ code each of them would need to set up a C++ testing framework first by messing with the CMakeList.txt file. This can be tedious and error-prone.

By adding a C++ testing framework by default we can improve the development experience and make life of students easier.

The 5th line of the file which checks out the uWebSockets repo to a particular commit, is commented:

git clone https://github.com/uWebSockets/uWebSockets 
cd uWebSockets
# git checkout e94b6e1

This causes problems during installation because the make command expects a CMakeLists.txt file, which does not exist if you do not perform git checkout e94b6e1.

Hi
When i run command cmake ..
I get error
CMake Error: The source directory "/home/masood" does not appear to contain CMakeLists.txt.
Any Solution

Thanks

For some reason I can't find the sources for the term 3 release of the self driving car simulator. All the contents in the repository relate to the previous term (jungle and lake tracks), but not to what I can see in the release version. Is anyone able to provide the sources for this?

I am new to these topic self driving car. I am curious about how was the Highway_map.csv data created which include x,y,s,dx & dy. Searched a lot but everyone has used the same data and no description about it. What if I want to create my own map in reality so how can I make the similar data which is in the highway_map.csv. Thank you in advance.

as example, and update bash scripts and README

[submodule "uWebSockets"]
	path = uWebSockets
	url = https://github.com/uWebSockets/uWebSockets

I wrote a function that returns the lane status, i.e. busy=1 or empty=0 for each lane. Usually it works perfectly fine and cars in adjacent lanes are detected if they are within a range of +-30m of the current car's "s" value. The result is show in the pictures below in the command line lanes line. But every now and then the location of the other cars does not seem to be transmitted, thus causing a collision.

when I compile this project
my terminal show me this"............/CarND-Path-Planning-Project/src/main.cpp:11:20: fatal error: Spline.h: No such file or directory
#include "Spline.h"
compilation terminated........."
copy Spline.h and SplineFwd.h to home/CarND-Path-Planning-Project/ then

Hello,

I start the executable by

./path_planning
Listening to port 4567

Then when I start the simulator and start the autonomous mode I get the following error

Connected!!!
terminate called after throwing an instance of 'std::domain_error'
what(): type must be number, but is null
Aborted (core dumped)

I am using Ubuntu 16.04

thanks in advance

Hi, Thanks for your great job! If I want to get the road network from the simulator, what should I do? I didn't find this kind of data in json data of main.cpp. Thanks !

It's my understand that this line is to check to see if the bearing-off-bow to the next waypoint (WPT) is behind the ego vehicle, which would be beyond 90 deg from nose of ego.

Thus this should be
if (angle > pi()/2)

instead of
if (angle > pi()/4)
???

I didn't touch any of main.cpp and I notice this error.

The README.md file says:

Main car's localization Data (No Noise)

["x"] The car's x position in map coordinates

["y"] The car's y position in map coordinates

["s"] The car's s position in frenet coordinates

["d"] The car's d position in frenet coordinates

["yaw"] The car's yaw angle in the map

["speed"] The car's speed in MPH

Please add units to the variables. Are the x, y, s, and d in meters? Is the yaw in degrees or radians?

If I understand correctly, the difference between car_s that we got from the simulator and that calculated using getFrenet should be small. However, as I drive along in manual mode, the difference between them goes periodically from 30 down to 0. Similar things happen for d. Are car_s and car_d the actual coordinates for the car or something else?

Hello,
When i run $ ./path_planning and start the term3_sim.x86_64,it shows that
Listening to port 4567
Connected!!!
But I can only use the manual mode.
Can you tell me how to start the autonomous mode?

thanks in advance
