RC type injection tank which hides secretly in the dark and aims secretly

I used to play with a radio control often when I was small, but it seems that radio controlled type tanks with syringes were produced as weapons for injecting drugs. It seems to be still a prototype, but how will it be improved in the future?

Picture from the top. I will aim for this sharp injection


What on the front is the serial port on the front?


It seems to have poisoned drugs injected by hitting bedtime. However, as long as such a sound comes out close to you, everyone seems to be alarmed, but let's not let it dare push it.
