I am trying to install the package on turtlebot 3 as explained in the website. but the installation has stuck at 44%.

The python shebang line (#!/usr/bin/env python) in control_lane.py (turtlebot3_autorace_driving/nodes/), detect_lane.py (turtlebot3_autorace_detect/nodes/), image_compensation.py (turtlebot3_autorace_camera/nodes/), and, image_projection.py (turtlebot3_autorace_camera/nodes/) should be updated to #!/usr/bin/env python3 for Python3 support as ROS Noetic supports Python3 exclusively.

The above can be applicable to all other python scripts/nodes in other sub-packages of the turtlebot3_autorace_2020 package.

python3-opencv dependency package issue.
Instead of installing the binary, you must download the source file.
This issue will be fixed soon.

Is there any new update for this project? Or is just been abandoned? Since the last update was two years ago

Hello,

Hope everyone is doing well =)

I used autorace 2019 on ROS melodic and one of the key points to make everything work was changing the camera's settings such as contrast, ISO, shutter speed, saturation etc.

I was able to do that because it seems that it used raspicam node instead of cv_camera and there was an extra folder called camera_calibration amongst extrinsinc and intrinsinc calibration folders also where you just had to change the values there.

Unfortunately, I'm not finding a similar folder for autorace 2020 using noetic. And trying to work with raspicam doesn't seem to work either (well, I can use it normally for image acquisition, but not with autorace 2020).

Did I do something wrong or was it supposed to be like this?

Thanks a lot in advance!

I'm trying to run Traffic Lights tutorial from Autonomous Driving section on ROS noetic, Ubuntu 20.04. But after I execute commands from tutorial, no traffic light appear in the gazebo world. How can I spawn traffic lights in my simulation?

I want to complete all missions at once processes like first kinetic version of turtlebot3_autorace.Do you have an existing example or tutorial?

Hi everyone,
i'm using a waffle pi and i'm following the steps of Autonomous Driving
i'm traying to preform the intersection mission and i couldn't succed, when the robot deteced the turn sign he doesn't stop and do the procedure to turn.
i tried 3 different method to test the program and the signs :

first i fixed the robot in a place between the lines and followed the instructions ( video 1)

the second video i stopped the bringup launch file ( the robot doesn't move but the procedure worked )
https://drive.google.com/file/d/1jbivgt0IeLjh7KyVSIGuhYwha1mNO20n/view?usp=sharing

the 3rd video i launched the robot using the site steps

Hi, I've been trying to get the lane detection code to work but keep getting this error:

AttributeError: 'DetectLane' object has no attribute 'left_fit'

The problem arises in line number 159 of detect_lane.py:
if yellow_fraction > 3000:
self.left_fitx, self.left_fit = self.fit_from_lines(self.left_fit , cv_yellow_lane)
self.mov_avg_left = np.append(self.mov_avg_left,np.array([self.left_fit]), axis=0)

Where we try to initiate self.left_fit while also using it in the function parameter. I've been struggling to figure out how to fix this problem, I've tried to initiate self.left_fit before this line (making it an array) but more errors occur. (I put the turtlebot between the yellow and white lines.) Any help would be greatly appreciated!
