git clone https://github.com/stack-of-tasks/eigenpy.git
cd eigenpy
cmake .
make 
sudo make install

cd build/Release
cmake ../..
make -j 8
sudo make install

2. mycobot_ros (Install from source)

sudo pip3 install pymycobot -U
cd ~/ros_catkin_ws/src
git clone --depth 1 https://github.com/elephantrobotics/mycobot_ros.git
cd ..
./src/catkin/bin/catkin_make_isolated --install -DCMAKE_BUILD_TYPE=Release --merge --pkg mycobot_communication mycobot_description mycobot_280 mypalletizer_260

3. USE 40-Pin

First, you need Jetson.GPIO installed. If not, sudo pip3 install -U Jetson.GPIO

The detail of pin-num are here

Then, you need to enable pin function manually, or the device does not work.

sudo /opt/nvidia/jetson-io/jetson-io.py

Configure Jetson 40pin Header -> Configure header pins manually -> enable pins (e.g. select pwm5 at pin-18).
