Root How can I root a Nexus 7 on android version 5.1 without a computer?

[MyLegGuy]

I have a Nexus 7 on android 5.1 and I want to root it.
However, my Nexus 7 can't seem to do anything with it's micro usb port. Excluding charging. Meaning I can't use a computer to do it.

So, are there any methods on android 5.1 for a Nexus 7 that does not require a computer to do it?
