Smart Robotic Arm Controlled Using Hand Gesture

The Smart Robotic Hand using OpenCV provides an effective and intuitive solution for natural human–robot interaction. By using camera-based gesture recognition instead of wearable sensors, the system offers a contactless, user-friendly interface that enhances accessibility. Real-time landmark detection combined with servo-based actuation enables accurate finger movement replication with minimal latency. The use of low-cost servos, an arduino uno controller, and a lightweight 3D-printed structure ensures both affordability and efficiency, making the system suitable for educational, assistive, and research applications. Overall, advancements in compact vision-processing frameworks, lightweight 3D-printed mechanics, and efficient microcontroller-based actuation collectively contribute to a robust and user-friendly gesture-controlled robotic hand. The technology demonstrates strong potential for future developments in assistive robotics, rehabilitation devices, remote manipulation, and educational platforms where natural human–robot interaction is essential.
