It would be really fun to display the set of positions (orientation included) at a given distance r of an origin position (orientation included). The "metric circle" of radius r. Maybe segment of this metric circle could even be colored according to which one of the 12 generic types of path it's part of). A given metric circle seems feasible to display, several "concentric" metric circle of increasing r might be but I guess it would be a mess in the display as they can cross each other (with same position but different orientation).
It is greatly prepared video, there are lots of detials and efforts in it. Thanks for video, I am looking forward for future videos of this serie. I wonder that is there variable speed of it. Or can we think the way that increase in speed means increase in radius. Can it be combine with RRT or A* algorithms? Lastly I wonder that are there automatic parking problems of trucks with trailer?
All good points. (1.)This is the path planning problem so it makes the shortest path. You can move along the path at any speed you want, but as you move faster the dynamics (changing gears, accelerating and decelerating, and not skidding out during turns) begin to become important. (2.) certainly at higher speeds the minimum turning radius increases. (3) certainly this is an excellent 'local planner' to use with RRT ruclips.net/video/Ob3BIJkQJEw/видео.html, PRM ruclips.net/video/tlFVbHENPCI/видео.html or A*. (3) motion planning for a truck with a trailer has a lot of great papers. Maybe someday I can find or make a Demonstration on that.

Hello, I want to learn all the codes of Reed-shepps, but I can't find them on this website, can you teach me how to find all the codes? And can you tell me how to learn Reed-shepps curve?
Sir Could you explain that how AutoTurn addon of AutoCAD works? and if possible could you implement it. It basicly takes initial vehicle position and end position with a given speed and it generates vehicle swept path. And it also work on truck with trailer
I think the addition of the trailer is the biggest difference, since increasing speed can be incorporated by increasing the minimum turn radius. autoturnonline.com/ shows the area swept out by the trailer. That is a good project, and I'll put it on my project list.
I answered too fast. The width of the swept path depends on the dimensions of the car and its orientation along the path. This is also an interesting challenge. See the figure here www.dimensions.com/element/passenger-vehicle-180-degree-turning-paths-radius that shows how different parts of the car body build the swept area. This will take some time!

Great video, thank you prof!
Thank you so much!

@@AaronBecker thank you sir, yes I am interested these kind of problems, someday I want to make it in godot

you can literally just watch this video??
Anyone have a photo of James Alexander Reeds III? (Jim Reeds). I couldn't find it and settled for a placeholder 😢.
Couldn't find anything either. Even looked for a headshot in his publications, but nothing. Thanks for the video.

Hi, I have tried to contact you through your email. If there are any possible research opportunities then I am hoping to collaborate with you. Thanks.
