Fast-Racing

An Open-source Strong Baseline for SE(3) Planning in Autonomous Drone Racing

0. Overview

Fast-Racing is a strong baseline that focuses on high-quality and extremely aggressive SE(3) trajectory generation.

The back-end optimization is a parallel extension of GCOPTER for drone racing, also powered by MINCO.

1. Setup

All the tests are conducted in the Linux environment on a computer equipped with an Intel Core i7-10700 CPU and a GeForce RTX 2060 GPU.

Moreover, Our software is developed and tested in Ubuntu 18.04, 20.04 with ROS installed.

ROS can be installed here: ROS Installation.

Also, we need to install gcc>=8.0.0 and Eigen>=3.3.0.

(Notion: if you are using Ubuntu 20.04, just ignore this step because higher version of gcc and Eigen have been installed while you are installing ROS; but if you are using Ubuntu18.04, you need to update these versions.)

Install gcc>=8.0.0:

1. Type the following command to install it.

   sudo apt-get install gcc-8 g++-8

2. Verify installation by:

   gcc-8 --version

Install Eigen>=3.3.0

You can download the source code package from Eigen Installation.

Please make sure to install the correct version.

Your can run the following command to check Eigen version.

sudo gedit /usr/include/eigen3/Eigen/src/Core/util/Macros.h

2. Download Track Binaries

1. Download the settings.json and move it to~/Documents/AirSim/settings.json.

2. Download any one of the tracks such as Zhangjiajie.zip, and unzip it.

3. Test it. Take Zhangjiajie as an example. Open a terminal window, cd to Zhangjiajie/directory. and type the following command:

   ./run.sh -windowed

3. Build on ROS

1. Install the dependence.

   sudo apt-get install libarmadillo-dev
   sudo apt-get install ros-${ROS_VERSION_NAME}-octomap*
   sudo apt-get install ros-${ROS_VERSION_NAME}-tf2-sensor-msgs ros-${ROS_VERSION_NAME}-tf2-geometry-msgs ros-${ROS_VERSION_NAME}-mavros*

   where ${ROS_VERSION_NAME} is the name of your ROS release.

2. Create an empty new workspace and clone this repository to your workspace:

   cd ~/your_catkin_ws/src
   git clone https://github.com/ZJU-FAST-Lab/Fast-Racing
   cd ..

3. Compile it.

   If your default gcc isn't 8 or greater (check using gcc --version), then compilation will fail. In that case, use gcc-8 explicitly as follows.

   catkin_make -DCMAKE_C_COMPILER=gcc-8 -DCMAKE_CXX_COMPILER=g++-8 

4. Run the Simulation

1. Run the track binary.

   Before the simulation racing, you need to run the rack binary.

   Open a terminal window, cd to Zhangjiajie/, Urbancity/ or Moderncity/ directory. and type the following command:

   ./run.sh -windowed

   2. Run the planner.

   Open a new terminal window, cd to ~/your_catkin_ws/ and type:

   source devel/setup.bash

   Then, run the script corresponding to the track. Take Zhangjiajie as the example:

   ./zhangjiajie.sh 

   After the global map is set up, you can use the 3D Nav Goal in RVIZ to trigger the planning.

Here is an example:

5. Use GPU or Not

Packages in this repo, plan_manage have GPU, CPU two different versions. By default, they are in CPU version for better compatibility. By changing

set(ENABLE_CUDA false)

in the CMakeList.txt in plan_manage packages, to

set(ENABLE_CUDA true)

CUDA will be turned-on to use the parallel architecture to speed up the computation of the optimization.

Please remember to also change the 'arch' and 'code' flags in the line of

    set(CUDA_NVCC_FLAGS 
      -gencode arch=compute_70,code=sm_70;
    ) 

in CMakeList.txt, if you encounter compiling error due to different Nvidia graphics card you use. You can check the right code here.

Don't forget to re-compile the code!

For installation of CUDA, please go to CUDA ToolKit
