The human hand was created to be a dexterous device by nature. The agility and flexibility of human hands are being replicated in some robotic system hands to improve grasping functions. People's labor will be greatly facilitated and protected by such manipulators. The goal of this study is to design and implement a "Wireless Hand Gesture Controlled Robotic Arm." The system is divided into three parts such as the accelerometer, the robotic arm, and the receiver. It is essentially an accelerometer and microcontroller-based system that uses a compact and low-cost 3-axis (DOF) accelerometer, the ATmega328, and the AT89S52MC to control a robotic arm remotely. This arm can move in two directions like vertically (up and down) and horizontally (left and right) (hold or release an object). An accelerometer is attached to the human hand, which records its movements (gestures and postures), and the robotic arm moves in response.
