posture correction robot

It's common for computer users to bend over in front of a screen, which can eventually lead to back problems. There are various gadgets on the market that solve this problem by constantly reminding users to sit up straight, but most of them are not fun. So I made a fun little tool for this problem. In this project I used Arduino Uno, mpu6050 sensor and 2 servo motors. The MPU-6050 is a low-cost, high-precision six degrees of freedom (DOF) inertial measurement unit (IMU). IMUs can measure acceleration, inertia, and many other parameters so you can determine their position and velocity in space. MPU-6050 is able to send data in i2c protocol. (SCL and SDA pins) There are many open source libraries available for use with this very common sensor, which can help reduce the learning curve for those who are not familiar with programming a fairly complex device. How it works: The mpu6050 sensor is attached to the person and when he/she bends over, the robot arm corrects the person's posture. I built the robot arm with the help of two SG90 servo motors. SG90 is a 180° rotating servo. Servo motors work based on PWM (Pulse Width Modulation) signals. As I said, the mpu6050 sensor is attached to the person's shoulder and when he/she bends over, the roll variable goes beyond 55 degrees, so the Arduino sends a signal to the servo to lift the robot arm and correct the person's posture. Return to the first position after 1 second.
