I have mobility which is three-dimensional
I am both innovative and unconventional
Diverse are my possibilities for deployment
One of these may be simply for your own enjoyment
I am a servant and you can become my master
But using me in the wrong place could spell disaster
A person or a computer controls my motion
I provide a vantage point over land or ocean
I am a tool for a practical application
Or I am simply a toy for your recreation
What am I?
