17-Year-Old Hiten Dharpure Breaks Micro-Engineering Limits with Tiny Robotic Arm

Hiten Dharpure of Nagpur has achieved his third consecutive Guinness World Record by building the world's smallest fully functional robotic arm, measuring just 39.25 millimeters. The device utilizes an Arduino-based control system and micro servo motors to achieve independent three-axis movement capable of gripping and transporting tiny objects. Dharpure designed the entire system from scratch using CAD software and 3D printing in a home workshop, aiming to prove that ultra-precision engineering is accessible through personal initiative rather than high-end laboratories.

Longitudinal Study Links Continued Employment to Cognitive Resilience in Older Adults

The study suggests that the mental stimulation and complex tasks inherent in employment maintain synaptic connectivity and functional brain networks, enhancing cognitive reserve. These findings highlight purposeful activity and vocational engagement as critical factors in extending the human cognitive healthspan.
