About the book: 1991 / On the planet Suleimen of the Jupiterian type there is a blue flag plant. The natives collect them, and the earthlings resell them to the planet Babur. The Baburites built their own KK and robots to assemble flags and sent them to Suleimen. The earthlings outwitted the arriving robots and the control computer: they pretended to be Baburites and reprogrammed the computer so that now it will not let anyone near it.
