Nagpur, Maharashtra teen Hiten Dharpure, 17 , set a new Guinness World Record for the smallest functional robotic arm. The arm measures 39.250 mm . This surpasses the previous record of 44.49 mm by 5.24 mm. Dharpure built the miniature arm using 3D printing technology. It incorporates micro servo motors and a custom control system.
Robotic Arm Capabilities
Despite its small size, the robotic arm can precisely lift and grip tiny objects. It features a 3-axis motion path. The arm operates using Pulse Width Modulation (PWM) signals. Dharpure developed the arm himself. He used FDM-based 3D printing. Micro servo motors are integrated. Custom mechanical joints ensure functionality.
Potential Healthcare Applications
Dharpure sees significant potential for the arm in the healthcare sector. He aims to scale up the prototype for practical use. Possible applications include precision microsurgeries. This development could advance medical procedures. The arm currently exists as a prototype.
Interest in Robotics
Hiten Dharpure’s interest in electronics began in childhood. His mother, Kavita Dharpure, shared that he would dismantle toys. This curiosity drove his passion for how things operate. As he grew, his focus shifted to electronics and robotics.
