If you have some source code in ~/ros/src/robocar110_ros/, try to do the following to update it.
cd ~/ros/src/robocar110_ros/
git fetch
First, if git status command shows changes, you can either remove them:
git reset --hard origin/master
, or save them:
git checkout -b new_branch
git add -A
git commit -m "commit message"
git checkout master
Then you can update the code with:
git pull
That's basic git usage. For more details, you can check the book for example, which is available on multiple languages.
Please, note that it's necessary to apply all Actions between current and new version from Release Notes!
If you have problems with rc110_robot_*.run file or you want another version installed, it's possible to do it with the following commands:
make deps
make install
