Derec has limited freedom to explore the subterranean operation and is amazed at the level of engineering design in the robots and their operation. Likewise, he begins to realize that he himself is well trained in robotics, both technically and psychologically (pertaining to the Three Laws of Robotics). Eventually, a passing alien pirate ship receives the robot's signal and attacks the colony. Due to the secrecy of the robot's mission, their orders dictate they must destroy themselves upon discovery. However, doing that would jeopardize Derec's life and thus the robots would be failing to obey the First Law of Robotics.

Un uomo si sveglia in un posto sconosciuto: ha perso la memoria e sta viaggiando su di un asteroide di ghiaccio. La sua sola possibilità di capire cosa fare è legata a una banda di robot che sta diligentemente ispezionando la superficie dell'asteroide alla ricerca di un misterioso oggetto. Il nome dell'uomo è Derec: tra varie peripezie, incontrerà una misteriosa compagna d'avventura, e il suo viaggio lo porterà in una strana città, differente da tutte quelle che vagamente ricorda: Una città-pianeta fantastica, un mondo che va al di là di ogni immaginazione, Robot City, una città abitata da soli robot.

Ancora senza memoria, Derec vaga su Robot City. Sempre con la presenza costante, ma quantomai indecifrabile, della sua compagna di viaggio, Katherine, l'unica a conoscere qualcosa sul suo passato, ma che per ragioni misteriose, non gliene parla. I giorni su Robot City saranno tutto un susseguirsi d'intrigo per Derec e Katherine, sospettati di delitto, saranno proprio loro ad indagare... e salvare Robot City.

In searching the Central Core for other options of self-rescue, they discover there are now three other unknown beings on the planet. Through interviewing random robots near sightings, they determine two of the three are a robot and a child, who is most likely starving due to the absence of food in an all robot city. They begin using their food replicator to produce food smells in hopes to attract the hungry visitor. It also involves a First Law priority to get the robots to help them search for the other inhabitants.

Latita ancora la memoria in Derec, l'unica presenza costante al suo fianco, su Robot City, è lei, Katherine. Questa volta il tema dell'indagine sarà il rapporto tra uomo e macchina.

Derec, Ariel, their alien companion Wolruf, and Derec's robot Mandelbrot are still stranded on a mystery planet in an experimental city entirely populated by uniquely designed robots. Robot City has no spaceport, space ships or any way to radio for help, and the Keys of Perihelion being produced by the robots will only work with robots, not humans or aliens. Thus, they have all exhausted their options of escape and are searching for other methods to get off the otherwise uninhabited planet.

Though the city is designed by the robots to support a human population, its design had been merely functional and utilitarian, until a building suddenly appears on the horizon that starkly contrasts the city's mundane architecture. It is a brightly lit, tetragonal pyramid and seemingly serves no purpose other than an artistic one. This is exceptionally odd since neither of the humans designed it and robots are logically incapable of the abstract thinking needed for producing art. Derec, Ariel, Wolruf, and Mandelbrot rush to see it up close to find almost every other robot in the city has done the same. This fact produces a double conundrum as robots are also incapable of appreciating art or being emotionally moved by it, yet there they are.

Derec e Ariel sono ancora sull'asteroide di ghiaccio.

Un killer robot sarà il mistero più pericoloso.

Derec, Ariel, their alien companion Wolruf, and Derec's robot Mandelbrot are still waiting in Dr. Avery's ship at the hyperspace relay star, Kappa Whale. Several weeks have passed since they arrived and no ship has shown up from which they could obtain navigation charts. Attempts to fix the hyperwave radio have proven futile due to the lack of knowledge of its workings. Boredom is setting in as well as an increased severity of Ariel's sickness. Something must be done.

Wolruf and Mandelbrot both agree Derec and Ariel should use the Key of Perihelion found on the ship to transport off the ship. Though, they don't know where they will be transported to, they assume back to Robot City. Upon activating the Key, they are transported to a small 2-room apartment, obviously not in Robot City. An old model robot in the apartment explains they are on Earth. Since Spacers aren't generally accepted on Earth, they immediately decide to make their way to a spaceport and leave for a Spacer world and medical care for Ariel. However, the nearest spaceport is in another city.

Derec, Ariel, their alien companion Wolruf, and Derec's robot Mandelbrot have returned to Robot City to convince Dr. Avery to remove the Chemfets he injected into Derec's blood while they were in his custody. From the top the Compass Tower they descend into the apartment on the uppermost floor. There they use the computer terminal to begin their search for the location of Dr. Avery, but have no luck.

Derec's condition is worsening quickly, so it is decided that Mandelbrot and Wolruf will enter the city and try to gain useful information. Wolruf being non-human and Mandelbrot being a robot allows them a bit of anonymity since Derek and Ariel would most certainly be noticed and reported.

Mandelbrot obtains a work assignment from the Central Computer and learns that all work is being automated to the point where it can be performed by "function robots", robots without positronic brains, after which only a skeleton crew of robots would be needed. All positronic robots have also been programmed with "Migration Programming" which is executed upon completion of their tasks, but Mandelbrot is unable to learn what Migration Programming is.

Derec must answer the call of a besieged city on an alien planet. His new challenge is to protect a fantastic metropolis of robots from wolf-like beings that stalk the perimeters and threaten its destruction! In Renegade, Ariel finds herself the sole human on a planet of positronic robots and an alien race of shocking intelligence. Can Derec and Ariel solve the mysteries of the robots and the aliens in time to stop an all-out-war?

The machinery of Robot City goes awry, and Derec Avery sets out to eliminate the source of the reprogramming, and Alliance, in which Derec restores the original Robot City, but now faces three subversive

Ariel follows her lover, Derec, to a planet of robots, where Derec is summoned to solve the mystery of the robots and aliens before a robot war erupts

Something is wrong with the original Robot City. Derec, Ariel, Wolruf and robots head back to that planet. When they arrive they find the streets deserted instead of busy with robot traffic, flaws in the buildings with further exploration they finally find Bogie a robot that spouts off lines from old movies, Timestep a dancing robot, and small human-like creatures. Unbeknownst to them WatchfulEye is the one that has taken control of the city, disabled the communication with Derec's chemfets and created the experiments that they chanced upon in the city.

The WatchfulEye robot decides to name itself Lucius II after the robot in an earlier story that showed creativity. Lucius along with Adam and Eve are still developing, trying to determine what is human. At one point Lucius is following Avery around because of a need to obey the second law. Later on the silverside robots have again redefined human in their minds so that they obey what they want to obey. This story is about developing the characters of those three robots.Derec, Ariel, Avery, Wolruf and the robots (including Mandelbrot) leave the original Robot city planet to go to the planet of the Ceremyons. The ship runs into some trouble and I thought there was a clever solution.Also Derec started having memories of his mother.

Derec Avery controls the web of robotic cities that are scattered throughout the universe, but these cities are not functioning like they should, and some of them are starting to become dangerous. Somebody else is manipulating them; it is Dr. Janet Anastasi, Derec's mother. In an unintended way, her interference is to the point of provoking a war between humans and aliens. A cataclysm is approaching and Derec has to find a means to avoid total destruction.

Derec, Ariel, Wolruf, Avery and the robots return to the original robot city to find the city gone replaced by a verdant ecosystem. Separately Janet Anastasi also makes her way to the planet. While the others are relaxing Avery grabs the three robots that are in a communication fugue, puts them in a lab ensuring they won't get loose again and proceeds to get enough material so he can study it. A limb will do. He cuts it off, triggering a third law response, but the magnetic field Avery created increases crushing them and frying their brains.Derec rebuilds Adam, Eve and Lucius with spare parts and recordings. Later on he finally meets his mother. Just an introduction, not a reunion.More delving into the three laws. The robots trying to come up with their own laws of humanics and trying to define humanity. Wolruf has to decide whether to bring robots back to her planet or it they'd be better off without them.

An experimental robot and a team of human experts are on the trail of a renegade robot that has broken itself down into six pieces and launched them into the past. The team must retrieve all the pieces before the human past--and its future--is changed.

An experimental robot named Hunter and his team of human experts must find and disable the MC Governor robot, which is lost in an age of pirates and cutthroats, before it can destroy all humankind.

MC Governor, the largest and smartest robot ever built, knew its destruction was imminent. It used the Third Law of Robotics-A robot must protect its own existence-to break itself down into six smaller robots and scatter them throughout Earth's past. It didn't realize that time travel would cause a change in its molecular structure. Now, if the robot's six parts are not found and returned to their own time, they will explode in a nuclear inferno, destroying humanity's future forever! Only an experimental robot named Hunter and his team of human experts can find and disable the MC Governor robot lost in the chaos of the Roman Empire's collapse. Their target is a robot who will risk all of history to escape them. A robot turned warrior.

A robot named Hunter and a team of three human experts travel back into time to World War II to stop a time-traveling renegade robot before he destroys the future of humanity.

Attempting to recover the fifth component of a renegade robot, Hunter and his team travel through time to ancient China, where they are thwarted by Dr. Wayne Nystrom, creator of the robot, who is determined to retrieve it himself.

The team travels to southern Britain to capture MC 6 in 459-in the time when a man named Artorius (King Arthur) led the Celts in war against the invading Saxons.
