## 准备
|
|
|
|
|
|
|
|
|
|
拉取代码(同步拉取子模块)
|
|
|
|
|
|
|
|
|
|
```bash
|
2024-03-14 11:36:49 +08:00
|
|
|
|
git clone --recursive https://github.com/fan-ziqi/rl_sar.git
|
2024-03-07 11:54:33 +08:00
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
如有更新:
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
git pull
|
|
|
|
|
git submodule update --remote --recursive
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
在任意位置下载并部署`libtorch`
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
cd /path/to/your/torchlib
|
|
|
|
|
wget https://download.pytorch.org/libtorch/cpu/libtorch-cxx11-abi-shared-with-deps-2.0.1%2Bcpu.zip
|
|
|
|
|
unzip libtorch-cxx11-abi-shared-with-deps-2.0.1+cpu.zip -d ./
|
|
|
|
|
echo 'export Torch_DIR=/path/to/your/torchlib' >> ~/.bashrc
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
安装 `teleop-twist-keyboard`
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
sudo apt install ros-noetic-teleop-twist-keyboard
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
## 编译
|
|
|
|
|
|
|
|
|
|
自定义代码中的以下两个函数,以适配不同的模型:
|
|
|
|
|
|
|
|
|
|
```cpp
|
|
|
|
|
torch::Tensor forward() override;
|
|
|
|
|
torch::Tensor compute_observation() override;
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
然后到根目录编译
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
cd ..
|
|
|
|
|
catkin build
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
## 运行
|
|
|
|
|
|
2024-03-14 13:11:01 +08:00
|
|
|
|
运行前请将训练好的pt模型文件拷贝到`rl_sar/src/rl_sar/models`中

2024-03-07 11:54:33 +08:00
|
|
|
|
|
|
|
|
|
新建终端,启动gazebo仿真环境
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
source devel/setup.bash
|
2024-03-14 13:11:01 +08:00
|
|
|
|
roslaunch rl_sar start_env.launch
|
2024-03-07 11:54:33 +08:00
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
新建终端,启动控制程序
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
source devel/setup.bash
|
2024-03-14 13:13:47 +08:00
|
|
|
|
rosrun rl_sar rl_sim
|
2024-03-07 11:54:33 +08:00
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|

### 实物
|
2024-03-07 11:54:33 +08:00
|
|
|
|
|
2024-03-18 14:53:31 +08:00
|
|
|
|
与实物的连接可分为无线与有线形式
|
|
|
|
|
|
|
|
|
|
* 无线:连接机器人发出的Unitree开头的WIFI **(注意:无线连接可能会出现丢包断联甚至失控,请注意安全)**
|
|
|
|
|
* 有线:用网线连接计算机和机器人的任意网口,配置计算机ip为192.168.123.162,网关255.255.255.0
