Multiple outlets profile 17-year-old Hiten Dharpure, an Indian student who builds what is described as the world’s smallest robotic arm. NDTV reports that the arm measures about 39.25 mm and is designed to grip and lift very small objects with precision. The reports state that the device uses 3D printing for the arm’s structure and micro servo motors to drive its movements. India Today similarly focuses on the claim that Dharpure created the world’s smallest robotic arm, presenting the work as an achievement based on the arm’s compact size and its functional ability to handle tiny items. Across the coverage, the emphasis is on the engineering approach—combining 3D-printed components with miniature actuation—rather than any specific application beyond demonstrating precise gripping and lifting. No additional performance metrics, testing details, or independent verification of the “world’s smallest” claim are provided in the supplied excerpts.
