Batman has had more than one partner during his long illustrious career. They have all brought something to the table, and have kept him in check at the same time, because if there is one thing that Batman needs, will always be a "Robin". The first person to be his partner, was Dick Grayson. Dick is a circus acrobat, and, with his parents, one of the "Flying Graysons". While preparing for a performance, Dick overhears two gangsters attempting to extort protection money from the circus owner. The owner refuses, so the gangsters sabotage the trapeze wires with acid. During the next performance, the trapeze from which Dick's parents are swinging snaps, sending them to their deaths. Before he can go to the police, Batman appears to him and warns him that the two gangsters work for Tony Zucco, a very powerful crime boss, and that revealing his knowledge could lead to his death. When Batman recounts the murder of his own parents, Dick asks to become his aide. After extensive training, Dick becomes Robin. They start by disrupting Zucco's gambling and extortion rackets. They then successfully bait the riled Zucco into visiting a construction site, where they capture him. Dick was his sidekick for years, and they had many adventures together, until he had a falling out with Batman, leading to an estrangement that would last for many years. The maturing Dick Grayson grows weary of his role as Batman's young sidekick.
Following the events of Batman's apparent death, 
With Dick now gone, Batman was without a partner, bring in Jason Todd.
Jason Todd is recast as a young street orphan who first encounters the Dark Knight while attempting to
Jason Todd discovers that Catherine Todd was not his biological mother, and runs away to find the woman who gave birth to him. After following a number of leads, including an Israeli Mossad agent and Shiva Woo-San, Todd finally tracks his mother, Sheila, to Ethiopia, where she works as an aid worker. While Todd is overjoyed to be reunited with his real mother, he soon discovers that she is being blackmailed by the Joker, who is using her to provide him with medical supplies. Sheila herself has been embezzling from the aid agency and as part of the cover-up, she hands her own son, who arrives as Robin, over to the Joker. The Joker beats the boy brutally with a crowbar, and then leaves him and Sheila in the warehouse with a time bomb.
Superboy-Prime alters reality from the paradise dimension in which he is trapped — his punches against the barrier keeping him from the rest of the universe causing temporal ripples — Todd is restored to life, breaks out of his coffin, and is eventually hospitalized; having wandered so far from his grave before his discovery, no connection was ever drawn between the two events, with groundskeepers covering up the disturbed grave rather than report it. Todd never turns up on any missing persons reports - as he was never 'missing' - nor can he be identified since no prints are on file for him. After spending a year in a coma and subsequently another year as an amnesiac vagrant after escaping the hospital, he is taken by Talia al Ghul after a small-time crook recognizes him as Robin due to his combat skills on the street.
Talia took Todd in out of her love for Batman, while her father, Ra's Al Ghul, was interested in the secret behind his resurrection. The League of Assassins tracked and eliminated everyone in Gotham who knew of Todd's resurrection to prevent Batman from finding out. They also interrogated the Joker's henchmen who were with him during Todd's murder, in hopes to find out how the boy could have survived. Talia later restored Todd's health and memory by immersing him in a Lazarus Pit in which her father was also bathing and helped him escape the house of al Ghul. It is suggested by Ra's that the power of the pit resulted in Todd's mental instability. Ra's refers to Todd as a "curse" and a "pestilence" unleashed on the planet, saying that madness may affect him in "hours, months, or decades". Todd learns various skills from various masters, assassins, mercenaries, and aviators around the globe, including guns, poisons and antitoxins, martial arts and acrobatics, and bomb-making. During his journey, Jason discovers that Batman has replaced him as Robin with another boy named Timothy Drake, which further torments him.
After learning of the Joker's arms deal in Los Angeles for another terrorism plot, Jason begins to stalk the villain as a masked assassin. After successfully capturing the Joker (who fails to recognize him), Jason contemplates burning him alive after dousing him with gasoline. However, Jason realizes that he does not simply want the Joker to die, but desires to punish both him and Batman. Jason spares the Joker and decides to wait for the right opportunity. Jason also admits to Talia that he has already deduced that the reason she finances his training is to stall him from killing Batman, but he has no desire to kill his former mentor anymore. 
Tim Drake is the son of Jack and Janet Drake, coming from the same social class as Bruce Wayne. When he was a young child, he visited the circus for the first time with his parents. The Drakes asked the Flying Graysons for a photo together, resulting in a momentary bond between Dick Grayson and Tim Drake as they met for the first time.
After reaching the age of nine, Drake deduces the identities of Batman and Robin as Bruce Wayne and Dick Grayson after witnessing a gymnastic move by Robin that Grayson displayed while performing with the Flying Graysons. Noting that Batman has grown reckless and violent following the death of second Robin Jason Todd, 
After Batman's apparent death, Bruce Wayne's biological son Damian Wayne takes up the Robin identity while Tim Drake, believing that his mentor is still alive, assumes the identity of Red Robin
After crippling Ra's al Ghul's League of Assassins, Drake returns to Gotham City to overthrow Ra's plans to use Hush, who was surgically altered to resemble Bruce Wayne, to gain control of the Wayne family resources by becoming the CEO and controlling shareholder of Wayne Enterprises in accordance to Bruce Wayne's will. Ra's al Ghul plans to destroy all that Batman held dear, and begins directing his assassins to target all of the Batman's associates. Realizing that these attacks are a smokescreen and that the real target is coercing Hush to sign away Wayne Enterprises, Red Robin decides to confront Ra's al Ghul head on. He calls upon all of his friends to protect the various targets. He distracts Ra's al Ghul from stopping Lucius Fox from making Drake the controlling shareholder of Wayne Enterprises. Realizing that Red Robin has bested him, Ra's al Ghul commends him, calls him 'detective,' and launches Tim out of the window.
This once again left Batman without a Robin. Enter Stephanie Brown, aka Spoiler. Creating a homemade Robin costume, Stephanie sneaks into the Batcave and demands that Batman train her as the new Robin. 
Damian is brought into the picture once Tim moves on to become Red Robin. Bruce's biological son, it is only befitting that there is actually a Father/Son team. Bruce returned to being the only Batman, while Dick has returned to his previous role as Nightwing. Damian still serves as his father's partner as Robin. After reading the letter written by his father from an alternate timeline, the Dark Knight decides that it is time to take steps to put his past behind him. He tries to teach Damian the same
values his parents have instilled within him as he finally assumes his role as a father. However, despite Bruce's attempts to build a relationship with his son, Damian remains cold and distant with his father, which Alfred worries about. This relationship is further strained when Damian kills the villain Nobody. During the "Leviathan" mission, when his mother Talia puts a price on his head and is targeted by the most dangerous and skilled assassins, Bruce faked Damian's death and secluded him in the Batcave in order to protect him while he goes undercover to confront Talia and her minions. But against his father's wishes he escapes, donning a new costume under the name of Redbird. Along with the mysterious Wingman and most of the Bat-family, Damian manages to rescue his father and defeat most of the League of Shadows. However, Batman explains that the temporary defeat of the League will not stop a larger force to attack later and destroy the city, so he came to the extreme decision that the only solution possible is that Damian to return to his mother, a decision that caused an emotional reaction on Damian like never before..
Damian Wayne is and always will be the best Robin of all times....
Along with the above mentioned Robin's, Bruce does have another ally on his side, that is Helena Wayne. Yes, I did just say Helena Wayne.
