Nice video! a question about the objective function: Is there a range of alpha beta and gamma? cause I'm working this report about DWA and got really cofused about that really good explaning though! Fan from Taiwan
Hi SJ Hsu! Thanks for watching my video. That is a difficult question. Alpha, beta, gamma values depend on your robot specification, environment, and how you want your robot to behave. I recommend you to search for other applications where DWA is used, and to compare these values. For example, here is the values for dwa_local_planner used in ROS (2.2.4 Trajectory scoring parameters). wiki.ros.org/dwa_local_planner
Hi, what a gorgeous explanation. Any chance to get access to the slides as well? I am a professor and would glady use it for my lecture (of course only with you giving proper credit). Greetings from Germany!
Hi T N! Thanks for watching my video! I have uploaded the power point file to the google drive. The link is in the description (it is the same link). Please check it. It is honor for me if you will use it at the university lecture!
Hi Minseok Jeon! Thanks for watching my video! In the real-world application, robot uses both local and global planners. But since this is a local planner tutorial, there is an assumption that the robot is close enough to the goal and global planner is not necessary.
Hi, if I were to implement DWA in a real robot hardware without a global planner, will it be possible for the robot to navigate through one static obstacle and if the goal point is not too far from the initial position?
Hi, i got some problem here. Can u share what package did u installed? I cant find "dwa_window" also simulator. So i use dynamic-window-approach 1.1.1 which is i use "import dwa" and still cant get the Ui_DWA_Simulator.
@@robotmania8896 i m sorry for another question, i run ur program on jupyter notebook (already convert .py to ipynb). But still error at import Ui_DWA_Simulator. So i still trying run on google colab and still doesnt work
@@temanperjalananmu What error exactly do you have? Please make sure that dwa_window.py is in the same directory with dwa.py and dwa.py has a valid path to “dwa_window.py”.
@@robotmania8896sorry sorry, already fix the problem. I miss dwa_window in the same directory. Ty robotmania for ur video, very useful if anyone want to learn about DWA
Well done! Simple but extremely useful. Best video I found to show to students.
Hello Omar Silva!

thanks for helpful, what is the simulation which using in video ?
Hi Nhat Tran!
Thanks for watching my video!
I have used python and pyqt5 to create this simulation.

Hi,
Nice video and thank you for the codes. I have one question. Does the robot solely depend on the DWA algorithm and not use any global planner?

@@robotmania8896 Got it. Thank you for your response!

Hi Minseok Jeon!
Yes, I think it is possible. But your robot should have means(for example lidar) to detect obstacles.

Hi Tan!

You don’t need any special packages. Just execute the dwa.py script.

Hi good work but what's the point of making a video of the slides ? Just share the slides if you don't speak no ?
Hi BORENSZTEJN Titouan!
Thanks for watching my video!
This is one of my earliest videos. In recent videos there is a voice.
