In the year 2019, the Robotics Club of Central Tanegashima High School has only one goal in mind: to create a working replica of the giant anime robot Gunvarrel! But doing so isn’t easy as the club only has two members: Aki, who took over the project from her now-graduated sister; and Kai, a lazy gamer who’d rather be elsewhere. What’s worse, the school’s vice principal has decided their club is a waste of school funds and plans to shut them down! Now, the duo must convince her otherwise by winning a fighting robot tournament and gaining new, machine-savvy members, but when Kai accidentally stumbles upon an unbelievable conspiracy, the Robotics Club becomes the least of his concerns...
The eccentric mad scientist Okabe, his childhood friend Mayuri, and the otaku hacker Daru have banded together to form the Future Gadget Research Laboratory, and spend their days in a ramshackle laboratory hanging out and occasionally attempting to invent incredible futuristic gadgets. However, their claymore is a hydrator and their hair dryer flips breakers, and the only invention that’s even remotely interesting is their Phone Microwave, which transforms bananas into oozing green gel. But when an experiment goes awry the gang discovers that the Phone Microwave can also send text messages to the past. And what's more, the words they send can affect the flow of time and have unforeseen, far-reaching consequences - consequences that Okabe may not be able to handle...
Both Robotics;Notes and Steins;Gate are anime based off video games developed by 5pb. Though their plots vary pretty drastically, they have a similar feel, as they both start out simply, with slice of life elements, but turn out to be something much more deep and intriguing.
Both are based off visual novels by 5pb, so they have a similair feel to them. Steins;Gate is darker, while Robotics;Notes is more light hearted. Both start off slow using humor to draw you in, but then unfold into something more intriguing. Steins;Gate pulls this off better than Robotics;Notes.
What really made me like Stiens;Gate was the logical consistancy that stayed true til the end. Instead of forcing a happy ending through shattering the logical barriers with something as clique as "the power of love", the resolution was found by digging deeper for another complex twist to solve everything; AND IT MADE SENSE!!! That alone makes it one of my top ten anime.
They share the origin (5pb, and both of them being a visual novel) and both of them are awesome on their own sense.They also share a somewhat similar setup starting off somewhat easy, humorous and with some "slice of life" vibe, but folding into something way more deep and complex.
Also, some of the characters from Steins;Gate have a grade of involvement in R;N like Daru and Nae Tennoji.
Feel Robotics Notes was lacking or you want more than Steins gate is superior in every way you won't be disappointed. With a superior cast of characters, better story, better sound track and a superb unique main character. I wouldn't be lying to say that this is at the top of its genre and easily an anime for your top 20 if not top 10.
Both stories derive from video games made by the same developers.
As for similarities, they are both based on a novel cast of characters who are united by a scientific hobby-related club, inventing in Steins;Gate and creating hobby/giant robots in Robotics;Notes. They are also both science fiction stories set in the present or near future of when they were written, so they are a different kind of science fiction story than you get if you are watching a show set far in the future.
Takumi is a reclusive otaku who wants nothing more than to be left alone to play online games and watch anime. He only attends the minimum necessary to pass his classes, and rarely leaves his cramped room except to purchase the newest figurines. One evening, while Takumi is chatting online with his friend "Grim," a stranger called "Shogun" joins the channel and, after "Grim" leaves, posts a series of disturbing photographs depicting a man impaled to a wall with metal stakes. The following day, Takumi is horrified when he wanders into an alley and once again sees Shogun’s images – but this time, the gruesome scene is reality. From then on, Takumi sees the world through a new set of eyes; imaginary delusions meld with reality, and he isn't sure who he can trust. With suspicions and confusion at every turn, Takumi must struggle to determine what's going on - but most importantly, whose eyes are those eyes?
Along with steins;gate, these animes are based off the virtual novels made by 5pb. however i feel that thier are also a lot of similarities between the two main charactors. thier both addicted to a video game and have the same kind of aura about them. its just that the main char of chaos head is insane.
Both stories are based off of video games from the same developer, as is Steins;Gate. Robotics;Notes and Steins;Gate actually share more similarities, but Chaos;HEAd also has a lot in common, such as being science fiction stories that take place in the present/near future, and involving advances in a particular area of technology: robots in Robotics;Notes, the inventions they work on in Steins;Gate, and internet-related and frankly all kinds of bizarre and mysterious possibilities in Chaos;HEAd (too hard to explain).
The most stark difference is the main chraracters, who are all actively involved in related fields in Robotics;Notes (as well as in Steins;Gate), whereas Chaos;HEAd features the classic pure otaku shut-in dragged into fantastical mystery. Also, Robotics;Notes and S;G are very group oriented, whereas Chaos;HEAd features a much more isolated protagonist, so his quirks, struggles and perceptions greatly dominate the narrative, as opposed to being provided with multiple perspectives.
Three years after an accident that nearly left him for dead, Tomoharu Natsume is about to start his high school life. Though with a ghost named Misao following him around, Tomoharu is far from being an average teenager. One day a strange woman appears and gives him a trunk that contains a tremendous power. This power is known as an Asura Machina - a being that draws its strength from a human sacrifice - and the sacrifice within Tomoharu's Asura is none other than Misao. As the bearer of such a power, Tomoharu immediately becomes the target of various groups, including the Divine Guards, who want his power for their own. When Tomoharu befriends a demon called Kanade and she is captured by the Divine Guards, he joins the Dark Society in order to save her. Now, Tomoharu will have to fight alongside the Dark Society while he tries to find a way to save Misao and bring her back to life.
AD 2019: the giant mecha known as LINEBARREL falls to Earth, grabbing the attention of the anti-machina organization JUDA. Before JUDA can arrive on the scene, an unfortunate accident occurs: LINEBARREL crashes into Kouichi Hayase, a weak and frail pushover of a boy. Waking up underneath a beautiful naked woman, Kouichi discovers that he now possesses great power and can summon LINEBARREL for his own purposes. All Kouichi has wanted is to become a hero of justice and hold his own, instead his childhood friends Yajima and Risako fighting his battles for him – and now he finally has that chance. With LINEBARREL's power, Kouichi becomes cocky and aggressive, lashing out at those he cares about most; and as a 'hero of justice', Kouichi must find his new place in the world and protect himself from two organizations who want their hands on LINEBARREL.
Giant robots piloted by kids and saving the world against all odds are common themes in these two anime. Linebarrels revolves around the main character and is more cartoonish, while R;N is more realistic and focuses equally (and well) on several characters, their relationships, and their backstories. Both are solid, entertaining examples of the mecha genre.
