Jetson Orin NX 开发指南（7）: EGO-Swarm 的编译与运行

一、前言

EGO-Planner 浙江大学 FAST-LAB 实验室的开源轨迹规划算法是，受到 IEEE Spectrum 等知名科技媒体的报道，其理论技术较为前沿，是一种不依赖于ESDF，基于B样条的规划算法，并且规划成功率、算法消耗时间、代价数值等性能方面都要高于其他几种知名算法。

而 EGO-Swarm 是基于 EGO-Planner 拓展的去中心化的无人机集群算法，有助于智能小车或自主无人机集群的规划的学习与开发

由于 EGO-Planner 是 EGO-Swarm 的一部分，并且他们的安装其实差别不大，因此本文主要介绍 EGO-Swarm 的编译与运行，参考

https://github.com/ZJU-FAST-Lab/ego-planner-swarm

https://github.com/ZJU-FAST-Lab/ego-planner

GitHub - ZJU-FAST-Lab/Fast-Drone-250: hardware and software design of the 250mm autonomous drone

由于 Jetson 系列开发板常用于当作机载电脑，因此本文介绍如何在 Jetson Orin NX 开发板上编译和运行 EGO-Swarm，当然本文对 EGO-Planner 同样适用。

二、编译 EGO-Swarm

首先安装依赖

sudo apt-get install libarmadillo-dev

然后创建并进入工作空间

mkdir -p ~/catkin_ws/src/
cd ~/catkin_ws/src/

从 GitHub 上下载 EGO-Swarm 源码

git clone https://github.com/ZJU-FAST-Lab/ego-planner-swarm.git

进入 EGO-Swarm 工作空间并编译

cd ~/catkin_ws/src/ego-planner-swarm
catkin_make

编译完成显示如下结果

三、运行 EGO-Swarm

接下来我们运行 EGO-Swarm，主要分为仿真和实验两个部分

3.1 EGO-Swarm 仿真

首先通过快捷键 ctrl + alt + A 打开超级终端，如果没有安装则参考下文安装

Jetson Orin NX 开发指南（2）: 基本环境配置_想要个小姑娘的博客-CSDN博客

将超级终端划分为两个终端，全选后 source 一下工作空间，终端输入

source ~/catkin_ws/src/ego-planner-swarm/devel/setup.bash

在第一个终端输入

roslaunch ego_planner rviz.launch

在第二个终端输入

roslaunch ego_planner swarm.launch

如下所示

依次执行可以得到如下结果

至此，EGO-Swarm 的仿真运行就实现了！

3.2 EGO-Swarm 实验

由于条件有限，我么在此仅仅只是将 EGO-Swarm 与 VINS-Fusion 进行连接，并且这里只涉及单个无人机（在这种情况下 EGO-Swarm 与 EGO-Planner 是等价的），其中 EGO-Swarm 单个无人机通过 VINS-Fusion 来获取里程计信息，同时通过深度相机数据来获取周围环境的情况。

3.2.1 创建文件配置

首先需要配置实验用的一些参数，对应于仿真中的 advanced_param.xml 文件，

其次需要配置调用 VINS-Fusion 里程计信息和 Realsense 深度相机信息的 launch 启动文件，对应于仿真中的 single_run_in_sim.launch 文件，

此外还需要用于可视化的 rviz 文件，对应于仿真中的 default.rviz 文件，

具体的配置可以参考 FAST-LAB 实验室的 fast-drone-250 中采用的 xml 和 launch 文件：

GitHub - ZJU-FAST-Lab/Fast-Drone-250: hardware and software design of the 250mm autonomous drone

主要是如下三个文件

但是由于 VINS-Fusion 中里程计发布的话题是 /vins_estimator/imu_propagate，而上面订阅的话题是 /vins_fusion/imu_propagate，这是因为在 fast-drone-250 中，vins_estimator 节点被重命名为了 vins_fusion，从而产生了差异，只需修改以下订阅的话题即可，其余的可以不做修改，（当然如果标定了相机内外参以及 imu 的噪声，则可以将之后的数据修改上去，VINS-Fusion 或者 EGO-Swarm 上都要修改），具体操作如下

在 ~/catkin_ws/src/ego-planner-swarm/src/planner/plan_manage/launch/ 路径下创建四个文件

3.2.2 VINS-Fusion-gpu + EGO-Swarm 实验

接下来我们先运行 Realsense 和 VINS-Fusion-gpu，如果没有安装 Realsense 和 VINS-Fusion-gpu，参考以下两篇文章

Jetson Orin NX 开发指南（4）: 安装 CUDA 和 Realsense_想要个小姑娘的博客-CSDN博客

Jetson Orin NX 开发指南（6）: VINS-Fusion-gpu 的编译和运行_想要个小姑娘的博客-CSDN博客

首先打开超级终端，划分为四个终端，

然后在第一个终端输入

roslaunch realsense2_camera rs_camera.launch

在第二个终端输入

source ~/catkin_ws/src/vins-fusion-gpu/devel/setup.bash
roslaunch vins realsense_d435i.launch

第三个终端输入

source ~/catkin_ws/src/ego-planner-swarm/devel/setup.bash
roslaunch ego_planner single_run_in_exp.launch

第四个终端输入

source ~/catkin_ws/src/ego-planner-swarm/devel/setup.bash
roslaunch ego_planner rviz_exp.launch

如下所示

依次运行后显示如下结果
