RuBullet
RuBullet is a Rust implementation of PyBullet. In other words, it uses the Bullet3 C API in order to expose a functionality that is similar to PyBullet. Development is ongoing and functionality is currently limited.
Status
Right now RuBullet should cover most of the basic use cases. It can:
- Create a PhysicsClient in Direct, Gui or other modes
- Load models from URDF, SDF, MuJoCo or Bullet files
- Create own models within the simulation
- Control robots in position, velocity or torque mode
- Calculate inverse dynamics, inverse kinematics, jacobians and mass matrices
- Render camera images
- Read information about links and joints
- Change dynamics of a body
- Create GUI sliders, buttons or put debugging text or lines in the simulation
- Get keyboard and mouse events
- Create and manage constraints
- Logging
- Saving states and loading states
- Set physics engine parameters
- Collision Detection Queries
- Deformables and Cloth
Things which are not implemented yet:
- Everything MultiDOF related
- Virtual Reality
- Plugins
The API is unstable and subject to change.
Example
use std::{thread, time::Duration};
use anyhow::Result;
use nalgebra::{Isometry3, Vector3};
use rubullet::*;
fn main() -> Result<()> {
let mut physics_client = PhysicsClient::connect(Mode::Gui)?;
physics_client.set_additional_search_path("../rubullet-sys/bullet3/libbullet3/data")?;
physics_client.set_gravity(Vector3::new(0.0, 0.0, -10.0));
let _plane_id = physics_client.load_urdf("plane.urdf", Default::default())?;
let cube_start_position = Isometry3::translation(0.0, 0.0, 1.0);
let box_id = physics_client.load_urdf(
"r2d2.urdf",
UrdfOptions {
base_transform: cube_start_position,
..Default::default()
},
)?;
for _ in 0..10000 {
physics_client.step_simulation()?;
thread::sleep(Duration::from_micros(4167));
}
let cube_transform = physics_client.get_base_transform(box_id)?;
println!("{}", cube_transform);
Ok(())
}
Bug reports and Merge Requests
The current development happens as a part of marcbone's master thesis. Therefore, merge requests can not be accepted until July 5, 2021. We are disabling merge requests until then which sadly also disables issues. If you find any bugs or have suggestions please write an email to one of the maintainers.
