The following lines are desirable for IPv6
::1 ip6-localhost ip6-loopback
This will support ROS networking.
You also may wish to install “chrony” to synchronize
the time different ‘nodes’ are running at. This is because
the Pi doesn’t have a real time clock, and if your Wi-Fi is not
connected to the Internet, the Pi will have the wrong time.
Next, I suggest you load the following ROS packages
into your catkin_ws/src workspace: ROS by Example Part 1
(RBX1) from Patrick Goebel;
rbx1 (this should go on both your laptop and the Pi); and
the SV-ROS Botvac nodes (courtesy of mostly Mr. Ralph
Raspberry Pi 3 mounted.
Follow the instructions in the README files to install
and test. For example:
git clone https://github.com/SV-ROS/intro_to_ros
