Close and restart the terminal.
Install python and adafruit libraries
# pip should be installed $ sudo apt-get install python-pip # install Adafruit libraries $ pip install Adafruit-MotorHAT $ pip install Adafruit-SSD1306
Add i2c too user
$ sudo usermod -aG i2c $USER
Create the catkin workspace
Create a ROS Catkin workspace to contain our ROS packages.
# create the catkin workspace $ mkdir -p ~/workspace/catkin_ws/src $ cd ~/workspace/catkin_ws $ catkin_make # add catkin_ws path to bashrc $ sudo sh -c 'echo "source ~/workspace/catkin_ws/devel/setup.bash" >> ~/.bashrc'
Close and open a new terminal window. Verify that your catkin_ws is visible to ROS.
$ echo $ROS_PACKAGE_PATH /home/nvidia/workspace/catkin_ws/src:/opt/ros/melodic/share
Install Jetbot_ros
Clone and build the jetbot_ros repo.
# git and cmake should be installed $ sudo apt-get install git cmake # clone the repo $ cd ~/workspace/catkin_ws/src $ git clone https://github.com/waveshare/jetbot_ros # build the package $ cd ../ # cd ~/workspace/catkin_ws $ catkin_make # confirm that jetbot_ros package can be found $ rospack find jetbot_ros /home/nvidia/workspace/catkin_ws/src/jetbot_ros
Test Jetbot_ros
