|
|
|
## 准备
|
|
|
|
|
|
|
|
|
|
|
|
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
|
|
|
|
|
|
|
|
|
|
|
|
将训练好的pt模型文件拷贝到`sim2sim/src/unitree_rl/models`中
|
|
|
|
|
|
|
|
|
|
|
|
新建终端，启动gazebo仿真环境
|
|
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
|
source devel/setup.bash
|
|
|
|
|
|
roslaunch unitree_rl start_env.launch
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
新建终端，启动控制程序
|
|
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
|
source devel/setup.bash
|
|
|
|
|
|
rosrun unitree_rl unitree_rl
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
新建终端，键盘控制程序
|
|
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
|
rosrun teleop_twist_keyboard teleop_twist_keyboard.py
|
|
|
|
|
|
```
|
|
|
