Nagpur, June 23 -- : A 17-year-old student from Maharashtra has entered the Guinness World Records by developing the world's smallest fully functional robotic arm, surpassing the previous record set by an American innovator.

Hiten Dharpure, a student of School of Scholars, Atre Layout, Nagpur, designed a robotic arm measuring just 39.250 mm, breaking the earlier Guinness World Record of 44.49 mm (1.75 inches) held by Kelton Serra of Indiana, USA.

The electromechanical robotic arm is capable of performing complex movements similar to a human hand. Equipped with micro servo motors and a precision PWM control module, it can move along three independent axes and accurately grasp small objects.

Hiten designed the custom chassis using FDM tech...
