Summary
In this chapter, you have learned how to look after your code and configuration. You have seen how things can go wrong, and the strategies to protect your work from them. You have a starting point with Git, SFTP, and SD card backups that you can use together to be a bit more experimental and fearless about changes to your robot. You can use SFTP to edit on your computer, giving you at least one copy other than the code on your robot and letting you use powerful editors. You can use Git to go back in time, so you can wind back from mistakes and experiments, or just see the differences. You can use SD card backups to get a complete image of the storage your Raspberry Pi is using, and restore it if it goes wrong.
In the next chapter, we'll start to build a basic robot. We'll assemble the robot chassis with motors and wheels, determine what power systems to use, then test fit the overall shape of our robot. Bring a screwdriver!
