Skills: Robot design, microcomputer control, Doctor of Engineering
Favorite Robot: Gundam


He is known to everyone in the humanoid robot industry. He began the development of humanoid robots in 2002 and has won the championship in Robo-One, and RoboCup tournaments. In addition, teams to which he provided robots won in numerous tournaments. He saw Gundam on TV for the first time when he was in junior high school and immediately fell in love with it. Ever since then, his dream has been to build a real-scale Gundam.  He has built over 50 kinds totaling over 200 robots.

Dr in the eyes of his fellow

He is very cool and collected and people call him a robot hermit. In a special TV program called Real Robot Battle, the team won the first prize. While all the other members were overcome with joy and their family members were crying loudly, he just held up his right hand nonchalantly.  At an event for kids, they asked him how to build a robot. He flabbergasted the event’s facilitator by saying “Well, you should first draw a plan using CAD” to the kid’s innocent question. By now, readers might have started to think that he himself is a robot. But he is a great family guy who drives his daughter to and from school every day. Ironically, his daughter dislikes robots; and therefore, he never talks about them at home. In addition, as reflected in his quick decision to purchase expensive parts if necessary, he is quite decisive and carries out his own words to build Mobile Suit Gundam.

Iron Man in the eyes of his fellows

Iron Man shared his desire to build a robot with Captain (Mr. Miki), and that led to the current robot project. He loves manufacturing and his job so much that he works almost every day except for New Year Day. He is always thinking about what to make next. He does not drink a lot because, according to him, he could spend that time on making something.
In private life, he is a joker and a great husband to his beloved wife, who is as curious and intelligent as to take programming lessons with him and write up patent application forms on her own.
He is such an up-beat lively person who always has a smile on his face and is kind enough to provide space for the project.

Captain in the eyes of his fellows 

Great leader with a signature beard
He always organizes the team together with a beaming smile. He is like the father of the robot project. He has maintained his beard and mustache since he was 25. He even refused to shave them off when his doctor told him to do so since it was getting in the way of the medical treatment he had to go through. He eventually partially gave in but maintained his beard. He is knowledgeable and fluent in three languages. He used to live in a remote part of the Philippines when he was young. It could be his old habit from those days, but he prefers to step into dangerous areas and blends right in whenever he goes overseas. He is always stopped at immigration and somehow a metal detector beeps each time. He is a gentleman and has a lot of topics for conversation. That’s why everyone thinks that he is absolutely popular with girls at a bar.

My interests are not limited to equipment plate working. 


He is the second son born to Araki Ltd., a family business part of Naniwa Cooperative Association located in Nishinari-ward. After Lehman Shock, he changed the company’s passive sales style to more proactive one and began to build a stainless Gundam little by little by himself, which in turn led to his participation in the 4m robot project. He now directly communicates with manufacturers. Adults as well as children love his stainless Gundam.

Ara-chan in the eyes of his fellows

He always carries out his own words. He never gives up until goals are achieved. The project sped up greatly after he joined the project. It is said that he is the most handsome, photogenic and flawless guy in the project. He is good at making others laugh. He is surely the class clown and essential to the 4m project.

Type S in the eyes of his fellows

He is picky about appearance and obsessed with making a “cool robot”. He has made the project’s logo as well as the exterior of the robot. He is very knowledgeable, especially of geeky trivia. Since he can do many things, he is always busy. According to him, he feels uneasy when he is not busy. He relentlessly gives his opinions to others even to his seniors including his older fellows of the project; however, since he does so out of good will, nobody gets hurt.

Skills:Planning and operation of amusement parks and theme parks
Favorite Robot: Transformer


I love amusement parks and theme parks so much that I make business out of them as well as spend chunk of my free time there.  Although I mainly plan new attractions and events for existing parks, I also have experience in launching new parks and managing ones. 
Side Note: When you are involved in amusement/theme park business, you can meet passionate people as well as make your own dream come true. I feel the same passion from the people in this robot project and it is my dream to show the 4-meter robot at museums and theme parks.
