As it stands, the user's phone might fall asleep (with the display turned off) while the user is using the web app. This can be dangerous because users no longer have ready access to the controls to stop the robot. Therefore, while the app is running, we should prevent the users' phone from going to sleep.

Here is a starting pointer for potential ways to do this. I don't know the best way to do this, so part of this issue is to investigate different ways to do it, decide which one is best, and why. The other part of this issue is to implement and test the ability to prevent the phone from falling asleep from the web app.
