17 वर्षीय छात्र ने बनाया दुनिया का सबसे छोटा रोबोटिक आर्म, गिनीज वर्ल्ड रिकॉर्ड में नाम दर्ज

A 17-year-old student from Nagpur, Maharashtra, has secured a place in the Guinness World Records after developing the world’s smallest fully functional electro-mechanical robotic arm. Measuring just 39.250 millimetres, the miniature device has broken the previous world record of 44.49 millimetres by 5.24 millimetres. Despite its tiny size, the robotic arm can grip and lift small objects with precision, showcasing the possibilities of advanced engineering in a compact design.

The achievement has drawn attention not only for setting a new world record but also for the potential practical applications of the invention. Hiten Dharpure designed the robotic arm using modern manufacturing and control technologies with the aim of exploring future uses in healthcare and precision engineering.

World’s smallest robotic arm sets new Guinness record According to news agency IANS, Dharpure built the robotic arm using FDM-based 3D printing technology. The device combines micro servo motors, PWM-based control systems and specially designed mechanical joints, allowing it to perform controlled movements despite its miniature dimensions.

The robotic arm features a three-axis motion path, enabling it to grip and move tiny objects accurately. By reducing the size while maintaining full functionality, Dharpure established a new Guinness World Record for the smallest operational electro-mechanical robotic arm.

Hiten Dharpure hopes invention will support healthcare Speaking to IANS, Dharpure said the current model is only a prototype, but he believes the technology could eventually assist doctors in performing highly precise medical procedures.

“This is a robotic arm that features a 3-axis motion path and runs on PWM signals. It holds great potential for application within the healthcare sector. Although it is currently in its prototype stage, our goal is to scale it up for practical use in healthcare, where it could eventually assist with precision microsurgeries,” he said.

If developed further, such robotic systems could support surgeons during delicate procedures that require exceptional accuracy and controlled movement.
Childhood curiosity inspired the record-breaking invention Dharpure’s interest in engineering began at an early age, according to his mother, Kavita Dharpure. She recalled that he often dismantled his toys to understand how they worked instead of simply playing with them.

Speaking to IANS, she said she was delighted by her son’s achievement and explained that his curiosity gradually developed into a passion for electronics.

“I am very happy. When Hiten was young, we used to buy him toys. He would always open them up to see how they worked. This curiosity about how things operate sparked his interest in electronics. As he grew older, he gradually started working more in the field of electronics,” she said.

The Guinness World Record marks an important milestone in Dharpure’s journey. His achievement highlights how innovation, technical skills and curiosity can combine to create technology with the potential to benefit society beyond setting records.
