IoT-Enabled and Hand Gesture Controlled Robotic Arm Using Blynk IoT and OpenCV
Abstract: Robotic arms have become vital in environments that necessitate control, stability, and remote operation. This study presents a low-cost, multifunctional robotic arm that operates in four distinct modes: gesture control using OpenCV, IoT-based control via the Blynk platform and ESP32, joystick- based manual control, and an automatic mode driven by coordinates stored on an SD card. The system integrates multiple control mechanisms through the ESP32 microcontroller and utilizes servo motors …
