Gesture-controlled robotic arms are being developed for prosthetics, helping amputees regain mobility and independence.
What is a Gesture-Controlled Robotic Arm?
A gesture-controlled robotic arm is a robotic system that moves in response to hand gestures. Instead of using buttons or joysticks, an accelerometer sensor detects hand movements and sends signals to an Arduino robot arm, which then moves accordingly. This technology is used in automation, rehabilitation, and even remote-controlled operations.
How It Works
The robotic arm functions by interpreting hand movements using an accelerometer. The accelerometer sends real-time data to the Arduino, which processes the information and controls the servo motors, making the robotic arm move accordingly.
Flowchart of the Process:
This method allows for seamless, real-time control of the robotic arm, making it an engaging and interactive robotic arm kit project for students.

Step-by-Step Guide
Step 1: Install Necessary Libraries
To communicate with the accelerometer and servos, install the required libraries in the Arduino IDE.
#include <Servo.h>
Step 2: Connect the Accelerometer to Arduino
Wire the accelerometer to the Arduino, ensuring proper voltage and signal connections.
int xPin = A0;
int yPin = A1;
int zPin = A2;Step 3: Connect the Servo Motors
Attach the servo motors to the PWM pins of the Arduino to control movement.
Servo base, shoulder, elbow, gripper;
base.attach(9);
shoulder.attach(10);
elbow.attach(11);
gripper.attach(12);Step 4: Read Sensor Data
Read accelerometer values to detect hand gestures.
int xVal = analogRead(xPin);
int yVal = analogRead(yPin);Step 5: Convert Hand Gestures to Arm Movements
Map accelerometer values to servo motor angles.
void moveArm() {
base.write(map(xVal, 300, 700, 0, 180));
shoulder.write(map(yVal, 300, 700, 0, 180));
}Step 6: Upload Code and Test the Arm
Upload the complete code to the Arduino, power the setup, and move your hand to control the arm.
void loop() {
xVal = analogRead(xPin);
yVal = analogRead(yPin);
moveArm();
delay(50);
