There are lots of potential answers to this question, so I guess I get to pick which I want to answer.
Robin in the comics is on Comic Book Time. That is, he's of variable (and usually not explicitly specified) age depending on the story, but typically is somewhere in his teens ... and most likely started in his early teens, since he was clearly Batman's sidekick for long enough to learn quite a bit about the super-heroing business before he became one of the founding members of the Teen Titans.
The Batman TV series was first shown on January 12. 1966. Burt Ward, who played Robin, was born in July 1945, so he was 20 when the series started. I think Robin was supposed to be a few years younger, though; it's pretty common for a teenaged character on TV shows to be played by an actor who's actually significantly older, because a) older actors tend to be better actors, b) they'll probably keep the same height within an inch or so and the same basic facial structure for the next decade so you don't have your audience wondering "who's that supposed to be" when you resume shooting after a hiatus and the actor is 4 inches taller and not "cute" anymore, and C) work restrictions for underage actors are a pain to deal with ... if you don't need them to clearly be prepubescent (in which case you kind of have to bite the bullet and cast a child) it's much less of a hassle to hire a young-looking 18-year-old to play a 14-year-old character.
Robins in the movies ... frankly, who really cares? Most of the movies with Robin in them were not nearly as good as the ones without, and I can't remember who any of them were anyway.
the old series = Adam West and Burt Ward the new series = George Clooney and Chris O'Donnell
Adam West played Batman and Burt Ward played Robin in the original TV series "Batman" that aired from 1966 to 1968.
There is no "Robin Beyond" if that's what you're wondering. Tim Drake (the second Robin from Batman: The Animated Series) appears in Batman Beyond: Return of the Joker, but never in costume. Dick Grayson (the first Robin) never appears in the series, although he is mentioned a few times and does have a role in the comic book series.
Old Wounds.
Depends on which Robin and which Batman series you're talking about. For an educated guess, I'm go with Batman: The Animated Series and The New Adventures of Batman. In Batman: TAS, Dick Grayson, like in the comics, was the first Robin. The last episode of Dick Grayson as Robin is the NAoB episode "Holiday Knights" In the NAoB, Tim Drake assumes the role of Robin in "Sins of the Father". Eventually he takes on the Role of Batman's new Sidekick
Robin is Batman's adopted son. Batman is not Robin's boss.
Robin follows Batman as he is Batman's sidekick.
The first Batman movie was released in 1966 and was directed by Burt Ward. It was based on the Batman and Robin television series at the time and featured almost all the same actors as the series.
George Clooney played the dark knight in "Batman & Robin" (1997) with Chris O'Donnell as Robin. The villains were Poison Ivy (Uma Thurman), Mr. Freeze (Arnold Schwarzenegger) and Bane (Jeep Swenson). The film took Batman nearly to the level of cartoonishness of the old TV series, and was so badly criticized that it caused the end of the first "series" of movies, until the Christian Bale reboot in 2005.

Better known as Burt Ward, or Robin in the Batman TV series.
If you are asking "Is Robin strong without Batman?" then the answer is definitely yes. All the Robins are very strong and physically able (acrobatics, combat training, etc.) and there have been several occasions where Robin has saved Batman (For example, in the short graphic novel series "The Cult" where Batman is completely brainwashed and pretty much helpless and Robin rescues him.)
