This repository is forked from [walk-these-ways](https://github.com/Improbable-AI/walk-these-ways), which is a Go1 Sim-to-Real Locomotion Starter Kit. It seems that [walk-these-ways](https://github.com/Improbable-AI/walk-these-ways) can be untilized on Unitree [A1](https://github.com/fan-ziqi/dog_rl_deploy) with simple modifications, since those robots are base on [unitree-legged-sdk](https://github.com/unitreerobotics/unitree_legged_sdk).
|
||||
|
||||
However, the brand-new architecture [unitree-sdk2 ](https://github.com/unitreerobotics/unitree_sdk2)is not base on UDP anymore, so this project aims to train and deploy walk-these-ways on Unitree Go2 by modifying SDK interfaces.

## Deploy on Nvidia Jetson Orin
|
||||
|
||||
To be continue:
|
||||
The Unitree Go2 robot is equipped with an onboard Nvidia Jetson Orin Nano/NX, which operates on an ARM-based architecture. Default information of this onboard computer is shown below, and you can connnect to Jetson by SSH, VScode(remote development) or plugging a HDMI cable.
|
||||
|
||||
```
|
||||
IP:192.168.123.18
|
||||
user name：unitree
|
||||
password：123
|
||||
```
|
||||
|
||||
### Requirements for Jetson
|
||||
- cuda
|
||||
- pytorch
|
||||
- miniconda (Omitted here; please install it by yourself)
|
||||
- cudnn (Omitted here; please install it by yourself)
|
||||
|
||||
|
||||
Two different ways are provided to set up correct environments in Jetson: through Internet or through Docker.
|
||||
|
||||
### Through Internet
|
||||
Connecting a Nvidia Jetson device to the internet can be done in two primary ways:
|
||||
|
||||
1. **Wired Connection**: Directly plug an Ethernet cable with internet access into the Jetson's Ethernet port. This method provides a stable and fast internet connection, suitable for tasks that require high bandwidth or low latency.
|
||||
|
||||
2. **Wireless Connection via USB Wi-Fi Adapter**: Purchase a USB Wi-Fi adapter compatible with the Jetson device. This method adds wireless connectivity, offering the flexibility to connect to the internet without the need for physical cables. However, it's important to ensure the USB Wi-Fi adapter is supported by the Jetson's operating system and drivers.
|
||||
|
||||
|
||||
|
||||
#### Check Jetpack Version
|
||||
Jetpack toolbox has been preinstalled on Jetson, you should check the jetpack vertsion firstly.
|
||||
```bash
|
||||
sudo -H pip install jetson-stats #Install jetson-stats toolkit
|
||||
sudo jtop
|
||||
```
|
||||
According to the detail information printed in the terminal window, the Jetpack version of my Unitree Go2 is `Jetpack 5.1.1 [L4T 35.3.1]`
|
||||
|
||||
|
||||
|
||||
You can also check libraries that have been preinstalled:
|
||||
```bash
|
||||
sudo jetson_release
|
||||
```
|
||||
#### Install cuda for jetson
|
||||
Check if there is a preinstalled version of cuda.
|
||||
```bash
|
||||
nvcc -V # check preinstalled cuda version
|
||||
```
|
||||
|
||||
If the preinstalled version if too high, you should uninstall it because, for instance, there is no Pytorch version that is compatible with cuda-12.2.
|
||||
|
||||
```bash
|
||||
sudo apt-get remove cuda
|
||||
sudo apt autoremove
|
||||
sudo apt-get remove cuda*
|
||||
sudo dpkg -l |grep cuda # check if any residual cuda file exists
|
||||
sudo dpkg -P Residual filename
|
||||
```
|
||||
|
||||
Personally, I recommend to install cuda-11.8. Click the link, [CUDA Toolkit 11.8 Downloads](https://developer.nvidia.com/cuda-11-8-0-download-archive?target_os=Linux&target_arch=aarch64-jetson&Compilation=Native&Distribution=Ubuntu&target_version=20.04&target_type=deb_local) , to check installation commands.
|
||||
|
||||
#### Install Pytorch for Jetson
|
||||
|
||||
Please [download](https://forums.developer.nvidia.com/t/pytorch-for-jetson/72048) pre-built PyTorch pip wheel installers for Jetson Nano, which is different from the way we install Pytorch on PC. Note that correct pytorch version should be chosen to make it compatible with specific version of cuda and Jetpack.
|
||||
|
||||
#### Run codes without cable
|
||||
As long as the environment and requirements on the Jetson are properly configured, you can follow the same deployment guidelines as you would on a PC. This liberates the robot! Now, you can test the code cable-free, offering more freedom to the robot's movements and applications.
