This kind of robots can be useful in our housework, offices, etc.
They can be also used at some factories.
I guess they should be used in future , because nowadays humans are very lazy, though government should allow robots now
There are a lot of benefits from using robot , as i already said it can helo us with housework , offices etc.
It should be miniature , smart, shiny, light, it can be transforming also
In my opinion it should work by sun rays , by energy of the majesty sun
