From Patna dreams to robotics glory: Rohit Ranjan builds Arsii, Bihar’s first female humanoid

From the bylanes of Patna emerges a story of determination, innovation, and an unshakable dream. Rohit Ranjan, a self-taught robotics engineer and founder of NeoGenTech, is reshaping Bihar’s identity in the world of technology.

With no foreign degree and no external funding, Rohit has built something remarkable, India’s first female humanoid robot, “Arsii.”

Arsii is more than just wires and code. She speaks like a human, recognizes faces, moves her hands to perform tasks, and engages in meaningful conversations.

Designed to look human-like, Arsii builds emotional connections with people in ways machines usually cannot.

What makes this achievement even more extraordinary is that every detail of Arsii, from design to coding, was developed in Bihar.

The project cost ₹6 lakh, a fraction of the several crores spent on international humanoids such as Sophia, Ameca, and Atlas.

Despite limited resources, Ranjan relied on his own earnings and the support of his parents to bring Arsii to life.

Unlike most robots built abroad that communicate only in English, Arsii can converse in multiple languages. Till now, she has been tested in English, Hindi, Bhojpuri, Maithili, Kannada, Marathi, and even Japanese.

This makes her adaptable across India in classrooms, hospitals, government offices, events, and research labs. Her multilingual abilities reflect not just technical brilliance but also cultural sensitivity.

Behind NeoGenTech lies a mission, to bring technology and robotics into every school, home, and village of Bihar.

Ranjan envisions a Technology and Innovation Center where children will experiment, build, and innovate beyond textbooks.

“We want every child, regardless of background, to have access to smart technologies and AI,” he said.

Currently incubated at the Chandragupt Institute of Management Patna, NeoGenTech is gaining mentorship and institutional support.

For Ranjan, this platform is a springboard to take Bihar’s homegrown innovation to national and global stages.

But Arsii’s story did not begin as an educational robot. During his graduation, Rohit dreamt of creating a defense robot for the Indian Army and even built a small prototype.

Limited funds, however, meant scaling it into a human-sized machine with defense-level strength was impossible. That is when he shifted focus to a friendlier humanoid, one that could help society in everyday life.

Piece by piece, Arsii evolved from an idea on paper to a robot with her own persona. Today, she is greeted not as a machine, but as an identity people love to interact with.

ARSII stands for Autonomous Robotic System with Integrated Intelligence. To Ranjan, however, it is more than an acronym. It is proof that Bihar can be at the heart of India’s technological revolution.

Ranjan is determined to see Arsii and future humanoids built in Bihar, in schools, hospitals, offices, and public spaces, leading India toward global leadership in robotics.

“Technology doesn’t have to be a tool of destruction,” Rohit says, reflecting on the sci-fi movies he once watched that depicted robots as threats. “If used with vision, it can be a force of beauty, support, and progress.”

Arsii is living proof of that belief, a robot with a heart, born not in Silicon Valley but in Patna.
