Notes:

Make sure that Atom is flashed into the top Atom, Transponder is flashed into the base Basic.
The firmware Atom and Transponder download address: https://github.com/elephantrobotics/myCobot/tree/main/Software
You also can use myStudio to flash them, myStudio address: https://github.com/elephantrobotics/myStudio/releases

Pip

pip install pymycobot --upgrade

Source code

git clone https://github.com/elephantrobotics/pymycobot.git <your-path>
cd <your-path>/pymycobot
# Install
[sudo] python2 setup.py install
# or
[sudo] python3 setup.py install

Or the more modern form:

# Install
pip install .
# Uninstall
pip uninstall .

## Usage:
