Python SDK - Revo1 Dexterous Hand

System Requirements

  • Linux: Ubuntu 20.04/22.04 LTS
  • macOS: 10.15+
  • Windows: 10/11
  • Python: 3.8 ~ 3.12 (Conda recommended)

Quick Start

Clone Repository

shell
# Using HTTPS
git clone https://github.com/BrainCoTech/stark-serialport-example.git

# Or using SSH
git clone git@github.com:BrainCoTech/stark-serialport-example.git

Installation and Configuration

shell
# Navigate to Python directory
cd stark-serialport-example/python

# Activate Conda environment (recommended)
conda activate py310

# Install SDK dependencies
pip install -r requirements.txt --index-url https://pypi.org/simple/

# If unable to install via PyPI, manually download and install the .whl file
# Download from: https://pypi.org/project/bc-stark-sdk/#files
pip install --force-reinstall '/path/to/bc_stark_sdk-x.x.x-cp38-abi3-manylinux_2_31_x86_64.whl'

# Configure serial port device permissions
# In Linux systems, serial devices (e.g., /dev/ttyUSB0) typically belong to the dialout user group
# Add current user to dialout group
sudo usermod -aG dialout $USER
# Note: You need to log out and log back in for this to take effect

# Run examples
cd revo1
python revo1_ctrl.py          # Single hand control
python revo1_touch.py         # Tactile sensor (tactile version)
python revo1_ctrl_multi.py    # Multi-hand control
python revo1_action_seq.py    # Action sequence
python revo1_cfg.py           # Device configuration
python revo1_dfu.py           # Firmware upgrade
shell
# Installation steps same as Ubuntu
# Note: macOS serial device names are typically /dev/tty.usbserial-xxx
shell
# If USB driver is not recognized, check serial port name in Device Manager
# Serial driver download: https://app.brainco.cn/universal/stark-serialport-prebuild/driver/CH340-drivers.zip

# Other installation steps same as Ubuntu
# Note: Windows serial device names are typically COM3, COM4, etc.

    Auto-detect Stark devices across all protocols (Recommended)

    - Scans for devices across CANFD, CAN 2.0, and Modbus protocols
    - Initializes the appropriate transport (ZQWL CAN/CANFD or Modbus)
    - Sets hardware type from detected device info

Touch Sensor API for Revo1 Touch version.

Touch sensor features:
- Multi-dimensional force detection: 3 normal forces, 3 tangential forces, 3 tangential directions
- Proximity detection: self-capacitance and mutual-capacitance
- Real-time data streaming: high-frequency data acquisition and callbacks

Check device type before use:

2. Enable and initialize touch sensors
3. Get touch data
4. Process touch data and implement control logic
5. Calibrate and reset touch sensors as needed
