Knowing Sirena – Week by Week!

Learning at Sirena:

I started my first week at Sirena by collecting information and understanding about our humanoid NINO. In this journey, I learnt about other Japanese humanoid Bots, collected information about their advanced technologies, also learnt about the reinforcement system used for humanoids. Some of the papers were in Japanese which I translated in English and read. Robotics was new to me so it was very interesting to understand the mechanism and control system of robots.

In the second week, I designed the foot of the Humanoid by 3D CAD Inverter. My colleagues helped me to learn and work on this tool efficiently.I started collecting information about gear and gear-box in my third week. It was necessary to know how a gear-box is built so I took some other company’s gear-box, dismantled it into pieces and learnt how it works.Now, it was the last week of my internship at Sirena. I designed the gear which was used for the gearboxes which played role in the joints of the humanoid. The calculation procedure and design was complicated and wasn’t easy to be understood by others, as i struggled with my English. I realized that i should learn to communicate better in English.

Ship sets sail, full throttle now.

It has been two years since the ship set its sail. It was the usual party that Jack Sparrow would pick, but more unusual ones on the way, in the sea! The ship was also built in the sea as we sailed along!

“Where were we sailing? Where to? How big was the ship? A ship that had no anchor!”

Sirena started as a humanoid Robotics company from India, which continues to be its main endeavor. In a sea of technology, that is accessible to all, what new, useful and exciting could we offer? Using the same tech solution on which NINO (Sirena’s flagship robot) is built, could provide music solutions for homes. Yes! The ship set its sail. We have, not one, but a range of speakers – Chorals – ready for pre-order! The team has since grown in tens, some reaching out to catch the sharks or dolphins, some building the decks, some test firing the guns – the flag is hoisted and ship is moving on.

What went into making Choral a classy desirable product?
The design team ensured, with several iterations, samples, rejections – that the best product lands in the hands of the user. Care was taken in choice of material, its texture and colors. The placement of the logo, its size. The package was designed and proto-typed. What to include or not in the box. How best could we make the buyer, the user, feel that they have indeed chosen wisely? It would be half baked if the presentation did not do justice to the real product. It would be unfair to glorify something that was not. Design team ensured users can truly feel the class of the product in the visual language, imagery and photography – ensure that you get to feel the product, in a true sense!

Lights. Camera. Nino.

We here at Sirena Tech are building a robo-boy named NINO, with capabilities that can surpass your imagination of having a companion for yourself, changing the Education system and human perception of technology and innovation altogether.

A boundless process driven by our extremely talented team, every moment here is memorable. Capturing all the moments and putting them together is lot of fun. Moreover, these also show how Nino has grown in time and how we are growing with him!

Now, let me take you through the journey where Nino is evolving and learning new things.

My job was to introduce Nino to the world through a video. At first, we tried to show the preliminary structure of Nino expressing himself through his body moments. How cool would it be to see two Ninos interacting? The idea popped up and we made a story out of all the actions Nino could do – with two Ninos. The shoot lasted for a whole day; Nino was a little camera conscious! Our engineers came into picture, held Nino tight and taught him how to act. At the end, both the Ninos were completely exhausted and start crying “low battery”, by then everything was in place and the outcome is here.

On Paper | Making of Sirena Brochure

Sirena Brochure had a whole set of requirements, a lot of text and almost everything that Sirena Technologies does. The brochure had to churn out an attractive design keeping in place all requirements. This process was a trip in itself. This post shares the nuances of a real world design process.


The brief consisted of a lot of text descriptions of products and offerings of Sirena. A lot of bullets and single lines, short paragraphs. The structure of text was upto two levels of sub bullets.

Design process

We first started with fixing a design template – two fold or three fold? out of A3 or A4? straight cut or silhouette cut? fold variations with discussions and review of the text, we arrived at key things the design must do. Bot is the hero while IoT Products and rest of Sirena activities are second. This translated to choice of images, and restructuring of the text. Rest of the iterative process was finding the right visual balance, interest and emphasis on elements on each page and fold.

Design iterations

We cannot get the best out without design iterations. Every element in the brochure had to be precise and polished hence, we played with compositions, layouts, colours, fonts and images to get the best output. The challenge was always the perceived “hard line” requirements. Continue reading

Getting Started with Mechanical Systems for Humanoid Robots


Getting Started with Mechanical Systems for Humanoid Robots -

The idea of building a humanoid robot can sound fascinating to many people but in reality it can be a very intimidating task. In this blog, we explain how to get started with the mechanical system of a humanoid robot and what are the challenges that can be expected along with their solutions.

A humanoid robot is a robot whose appearance and motion is similar to that of a human. In general, a humanoid robot has a torso, two legs, two arms and a head. Continue reading
