Dr. Bolivar Trask was concerned with the emergence of the species 'MUTANT', that their genetic abilities, combined with their ever-increasing numbers would lead to Homo Sapiens being subjugated by them. That was the motivation that spurred him to create his "Master Mold", a servitor/controller that would command the many 'Sentinels' that Trask would create later. Unfortunately the A.I. it had been given, began to grow exponentially and Master Mold became sentient, and made sure his progeny acquired this ability also. Ironically, unbeknownst to Trask he had fathered two children who would grow up to become mutants: Tanya (and Lawrence) who had the ability of time travel and due to the instability of her power became lost in the timestream.
When Bolivar discovered that Lawrence was 'gifted' with precognition, he went to great lengths to create a device that would cloak his son's genetic ability (from his guardians) and hid it within an amulet, that he gave Lawrence, after Bolivar realized his son had predicted his wife's death. Trask had created humanity's guardian in Master Mold, but had not factored in Sentinel Logic in problem-solving, "We were created to be the Guardians of Mankind - and to guard them properly we must RULE them completely".
Master Mold commanded the existing Sentinels to capture their creator and return with him, So that he could commence the creation of a vast army of Sentinels with the intention of World domination. Trask, after witnessing Beast's interrogation under the Psycho-probe, realized that it was he, who had created the threat. To right His Wrong, in a attempt to destroy Master Mold, he sacrificed himself by triggering a catastrophic explosion. The X-Men barely escaped, Bolivar was found by his son, who, from that day blamed Mutants (specifically the X-Men ) for his father's demise, and made it his project, to vastly improve on his father's design, initially converting the Mk I's then eventually creating the superior Mark II Sentinels. They could identify/determine a mutant's power from a distance due to an encyclopaedic database and advanced scanning equipment, and could conceive a plan to nullify/neutralize all mutant powers/attacks, and incapacitate any opponent.
Judge Chalmers (a close family friend) abhorred by Lawrence's extreme solution, (and privy to the family secret) decided to shock his young ward by snatching the amulet about his neck (That, to that day had hidden his presence from his servitors) No longer masked by the amulet, his former servitors, apprehended Trask and followed his last order as their leader, "Secure All Mutants in area - - and DESTROY them", Needless to say the X-Men triumphed and saved the Day. In a future confrontation with his creations, Lawrence became involved, when Quicksilver used him, to locate his sister (the Scarlet Witch) who had been abducted by the Sentinels, (the Mark IIs lead by their (unbeknownst to them) Now mutated leader, No. 2, from their aborted mission to the Sun) in their latest scheme to rid the world of Mutants. Unfortunately, He too, came to an untimely end, crushed beneath one of his creations like his father.
Even though two generations of Sentinels had failed in their objective, the technology still lived on, the US government took possession of Trask's blueprints and specs, wherein (Steven Lang and later) Sebastian Shaw set out to build a new line of Sentinels.
The Sentinels were created by Stan Lee and Jack Kirby. The Sentinels made their first comic book appearance in X-Men #14 (vol.1). They have also been known by other nomes de guere for example, Enforcers (X-M:AS) and Exonims (Age of X) and Servidores (X-M:Legacy #238-#239).

Master Mold was created by Bolivar Trask as the prototype to subsequent Sentinels. It's primary objective was to hunt down/capture mutants, secondly to create more Sentinels, (in order to achieve this, with optimum results) it evolved and became sentient and concluded world domination was the most efficient way to achieve it's Directive.
First Appearance Uncanny X-Men #191
Nimrod was created in the alternate reality "Days of Future Past" and was the most advanced Sentinel of it's time. It pursued Rachel Summers sideways through time (E-616) to the X-Men's present and became a vigilante. It later evolved into the human-like Bastion.
First Appearance X-Factor #123
Sentinels looked upon humans as weak, to rectify this, Bastion converted humans into 'sleepers' using Cybernetic and Nano technologies, and christened them Prime Sentinels.
First Appearance X-Factor #123
Bastion had outfitted some Prime Sentinels (Nimrod Battalion) that resembled the original ones, with superior power output, they could fly and fire energy blasts from their hands. Like all Sentinels, their Prime Directive was to eliminate Mutants.
First appearance Avengers & X-Men: Axis #1
After stealing the brain of the deceased Charles Xavier, the Red Skull was able to brainwash Tony Stark into creating a new breed of Sentinels to help cleanse the world of its superhuman population. Created from nearly indestructible adamantium shells and possessing Stark's superhero files from the Civil War, the Stark Sentinels were able to quickly subdue the Avengers and X-Men with little issue. They were defeated after the arrival of Magneto's makeshift army of supervillains, as Stark did not have the foresight to include countermeasures against criminals.

The Sentinels appear as the primary antagonists of the film. In the movie, it is revealed that the earliest models of Sentinels were developed by Bolivar Trask during the early 1970's, but after Trask was murdered by Mystique, the machines were upgraded by integrating the shape-shifting mutant's DNA.
By 2023, the Sentinels have wiped out most of the human race and can now adapt and counteract any mutant superpower. With the X-Men hopelessly outmatched, Kitty Pryde sends Wolverine back in time to prevent Trask's assassination and stop the Sentinel program from ever taking off. The young Magneto manages to hijack the Sentinels and uses them to attack Washington, D.C., but is stopped by Mystique, who is convinced by Charles Xavier to spare Trask's life. As a result, Trask is discredited and arrested for leaking military secrets, which leads to the dark, Sentinel-controlled future never coming to pass since the Sentinel project is scrapped following Trask's incarceration.
In the movie, the original 1970's Sentinels resemble more realistic versions of their comic counterparts, while the futuristic Sentinels deviate more heavily. According to designer John Myhre, this was to allow the Sentinels to change their size and shape in order to adapt to any threat.
