Important Information

2018/11/20

There is one unconfirmed supplement about the test. It is usually fine but unless you immediately execute f. flush() when writting a word into the dummy device with the test code, there will be delays in file inputs, which leads to the tests being mocky.

By following the procedures listed here https://wiki.ubuntu.com/ARM/RaspberryPi#Wifi we have confirmed that one can install a firmware where the WiFi is enabled. -> wifiproblem.md

2018/6/11

When installing the newest ROS and executing catkin_create_pkg, the format of package.xml is generated as version 2. Since in this version run_depend is replaced by exec_depend, you will need to replace the run_depend to exec_depend written in the text. If you would like to use the old version, delete the line format="2" written in the top of the XML. Although, it will be better to learn the new version.

We have just noticed this but the WiFi does not work with the method shown in 2017/05/06. It is under investigation and in the mean time please do as follows.

• If you have already installed it and the WiFi works, do NOT apt upgrade.
• If you are about to install, use the image here.

There wasn't a log of the simulator (Chapter E) at the time of writing, so we have made a branch of it.

In chapter 10, because there was no xml file in the specified path, an error will occur in OpenCV.
