I finally succeeded in my 11th experiment,
because I could directly observe the target's parts, there was a big progress in my research.
There is a mother device inside the mech that can sense other subdevices and recognise friend or foe.
It seems to be a sensing device created by a mad scientist, so that these machines won't attack each other.
But I have no idea what the theory of this sensor is. It's safe to say that the original creator was extremely outstanding.
I have to record this result quickly!
