rrt

RRT (Rapidly-exploring Random Tree) library in Rust

Using this crate

In your Cargo.tml, add below.

ini [dependencies] rrt = "0.1.0"

Examples

There are an example to solve collision avoid problem.

bash cargo run --release --example collision_avoid

Below is the simplest example. It search the path from [-1.2, 0.0] to [1.2, 0.0] avoiding [-1, -1] - [1, 1] region. There are only one function dual_rrt_connect, which takes start, goal, is free function, random generation function, unit length of extend, max repeat num.

rust extern crate rand; extern crate rrt; fn main() { use rand::distributions::{IndependentSample, Range}; let result = rrt::dual_rrt_connect(&[-1.2, 0.0], &[1.2, 0.0], |p: &[f64]| !(p[0].abs() < 1.0 && p[1].abs() < 1.0), || { let between = Range::new(-2.0, 2.0); let mut rng = rand::thread_rng(); vec![between.ind_sample(&mut rng), between.ind_sample(&mut rng)] }, 0.2, 1000) .unwrap(); println!("{:?}", result); assert!(result.len() >= 4); }
