|
|
|
|
|
|
|
|
|
|
```cpp
|
|
|
|
|
torch::Tensor forward() override;
|
|
|
|
|
torch::Tensor compute_observation() override;
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
然后到根目录编译
|
|

|
|
|
|
|
|
|
|
|
* 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

## 添加你的机器人
|
|
|
|
|
|
|
|
|
|
下文中将ROBOT代表机器人名称
|
|
|
|
|
|
|
|
|
|
1. 在robots文件夹中创建名为ROBOT_description的模型包,将模型的urdf放到文件夹中的urdf路径下并命名为ROBOT.urdf,在模型文件中的config文件夹中创建命名空间为ROBOT_gazebo的关节配置文件
|
|
|
|
|
2. 将模型文件放到models/ROBOT中
|
|
|
|
|
3. 在rl_sar/config.yaml中添加一个新的字段,命名为ROBOT,更改其中参数,如将model_name改为上一步的模型文件名
|
|
|
|
|
4. 在rl_sar/launch文件夹中添加一个新的launch文件,请参考其他launch文件自行修改
|
|
|
|
|
5. 修改rl_xxx.cpp中的ROBOT_NAME为ROBOT
|
|
|
|
|
6. 编译运行
