Custom distribution for sampling-based motion planning

An RRT grows a tree rooted at the starting configuration by using random samples from the search space. As each sample is drawn, a connection is attempted between it and the nearest state in the tree. If the connection is feasible (passes entirely through free space and obeys any constraints), this results in the addition of the new state to the tree. With uniform sampling of the search space, the probability of expanding an existing state is proportional to the size of its Voro… WebMar 7, 2024 · 好的，以下是使用 C 语言编写 RRT 算法的示例代码，用于检测两个点之间的路径是否与障碍物相交，与此相关的函数也将包括在内： ```c #include #include #include // Define constants #define PI 3.14159265358979323846 #define K 5000 #define GOAL_BIAS 0.10 #define STEP_SIZE ...
