In this video I explain how RRT (path/motion planning algorithm) works. Please visit arms.nu.edu.kz/... for more information. If you find a mistake or an error please let me know olzhas.adi@gmail.com . olzhas.github.io

why the down votes, this is a really good explanation. it's not a cat video. no need to hate if you can't do a better version

Very nice explanation, but you didn't add that you keep moving towards q_rand in steps of e (=step_size) until you reach q_rand, rather than just one step. The only thing that could this movement is if an intermediate node q causes collision with an obstacle.

Hi, I have two questions: 1) Is qrand's distance relevant or we only care about direction? 2) What is the point of finding random nodes in the vicinity of qr? What is the goal of the algorithm? Thank you...
@OlzhasA8 жыл бұрын
1) don't care at this stage about the distance of direction, we just propose a random state. 2) we use it to explore the state space of the define problem. The goal is defined by a user.

if a random node which is generated in an obstacle area, we will keep that iteration or start a new iteration to generate a new random node?
@OlzhasA5 жыл бұрын
It is not a valid node, hence proceed to the next iteration.
@van-vivo11715 жыл бұрын
How about the case, we found a new node which is in a collision-free area, but the path from the nearest node to the new node collide with the obstacle? In this case, we will ignore the path and the new node or only the path? Thank you
@OlzhasA5 жыл бұрын
in that case you don't add anything to the tree, and start a new iteration.

how are those random nodes generated? Any specific/dominant way or any other ways..?
@OlzhasA6 жыл бұрын
the state would be generated with a pseudorandom number generator. The example of a state is a vector. So, if your state is a 2D vector, you just generate 2 numbers in some boundaries.

Not to offend. But why repeated opening and closing of markers. Why dont u just open and hold it bro.
