Making the robot fully phone-operable

The goal here is to make it so that we can drive the robot completely from the phone. We need to ensure that the robot is ready to run when we turn it on, and make sure that the menu is usable from a phone. The menu we made earlier doesn't seem very touch-friendly. It also will not successfully run any of the behaviors with displays using Flask. We will make the menu buttons bigger and more touch-friendly, using styles similar to our manual drive behavior. The menu will also load our server page after clicking a behavior with a server such as this one or the last chapter's visual tracking behaviors.

Let's fix the Flask behaviors first.

Making menu modes compatible with Flask behaviors

If you've already tried running Flask-based behaviors (such as those with a camera) in the control server, you will have noticed some very odd behavior. Your behavior will appear to do the right thing with sensors on the robot, but the...
