I like to setup wireless networking on my robots. Robots should go untethered! Here is how. It's easy in an interactive tool call `connmanctl`. You connect once, and next time you boot, it's all configured. On my ev3dev machine it went like this:

You're all set up now! After reboot connman automatically finds your local wifi again.

I prefer to have a passwordless ssh to the robot. For this I [add a user with the same login name as on my development computer.](https://www.raspberrypi.org/documentation/linux/usage/users.md) Remember to give yourself sudo rights as explained on that same page.

After adding that user, you can [set up passwordless ssh](https://www.raspberrypi.org/documentation/remote-access/ssh/passwordless.md).

With the IDE (PyCharm) set up and the library installed you can code much faster. PyCharm will highlight most coding errors and typos. It will also suggest to autocomplete your code and show documentation. Let's try.
