A Python library for controlling HexDevice robots and devices

Hex Device Python Library

中文 | English

Overview

This library provides a simple interface for communicating with and controlling Hex devices. It uses Protocol Buffers for message serialization and WebSocket for real-time communication. The supported hardware list is as follows:

• [✅] ChassisMaver
• [✅] ChassisMark2
• [✅] ChassisTriggerA3
• [✅] ArmArcher
• [✅] ArmSaber
• [✅] HandsHtGp100
• [-] hex_lift

Installation

Install from PyPI (Recommended)

pip install hex_device

Clone the Repository (Development)

git clone --recurse-submodules https://github.com/hexfellow/hex_device_python.git

Prerequisites

• Python 3.9 or higher
• Anaconda Distribution (recommended for beginners) - includes Python, NumPy, and commonly used scientific computing packages

Quickstart

Install protoc

1. Install protoc from package manager (Recommended only for Debian13/Ubuntu24.04)

   sudo apt install protobuf-compiler
   

2. Install protoc from Github Releases (Recommended Ubuntu22.04 and below)

   Just choose a suitable version and install it. Here below is an example of installing protoc-27.1.

   # For Linux x86_64
   wget https://github.com/protocolbuffers/protobuf/releases/download/v27.1/protoc-27.1-linux-x86_64.zip
   sudo unzip protoc-27.1-linux-x86_64.zip -d /usr/local
   rm protoc-27.1-linux-x86_64.zip
   
   # For Linux arm64
   wget https://github.com/protocolbuffers/protobuf/releases/download/v27.1/protoc-27.1-linux-aarch_64.zip
   sudo unzip protoc-27.1-linux-aarch_64.zip -d /usr/local
   rm protoc-27.1-linux-aarch_64.zip
   
   # Verify installation
   protoc --version # Should be or more than 3.21.12
   

Install hex_device

Option 1: Package Installation

To install the library in your Python environment:

python3 -m pip install .

Option 2: Direct Usage (No Installation)

If you prefer to run the library without installing it in your Python environment:

1. Compile Protocol Buffer messages:

   mkdir ./hex_device/generated
   protoc --proto_path=proto-public-api --python_out=hex_device/generated proto-public-api/*.proto
   

2. Install dependencies:

   python3 -m pip install -r requirements.txt
   

3. Add the library path to your script:

   import sys
   sys.path.insert(1, '<your project path>/hex_device_python')
   sys.path.insert(1, '<your project path>/hex_device_python/hex_device/generated')
   

Usage

The complete function interfaces can be found in our wiki.

• A simple demo for all device: test/main.py

• Example of robotic arm trajectory tracking: test/archer_traj_test.py

Q&A

Why did a previously working software package stop working after a redeployment?

• Please check the Change log to see if you are using cross-version software packages

If I want to use newer software packages, how do I perform hardware upgrades?

• Please contact our after-sales service, and we will provide hardware upgrade instructions based on the equipment you purchased
