You can find this in I, Robot and The Complete Robot.
A lot better than the last one. Powell and Donovan are back, this time they’re testing a new mining robot, on an asteroid, that has six robots slaved to it like fingers of a hand. Everything works great while they’re observing the robot, but as soon as they leave it to get on with things on its own no mining gets done, and they have 10 days to sort it out before they get the sack.
And now i’m off straight into the next robot story, Liar!: finally into the Susan Calvin stuff.
