Use attach( ) function to declare the pins to which your servo motors are attached and set the initial position of your servo motors as zero within void setup( ). The robotic arm is made using two micro servo motors so you will be needing the Servo library for your microcontroller to control the servo motor movement. Roll (longitudinal axis), pitch (transverse axis) and yaw (vertical axis) are aircraft principal axes.įor this project, we will be using only the roll and pitch measurements to control the simple robotic arm. Rotate the sensor module to notice the changes and identify the roll, pitch and yaw. Upload it to your Arduino microcontroller board and observe the readings produced by the sensor module. Go to File menu from the top menu bar and select the MPU6050_DMP6 example sketch from the MPU6050 library. To learn more about the libraries, please visit Jeff's website.

SCL - D21 (Arduino Mega 2560), A5 (Arduino Uno and Nano)Īs I already mentioned in above, you will be needing Jeff Rowberg's I2C Development library and the MPU-6050 library to interface your MPU-6050 sensor module with the Arduino microcontroller board.

This voltage is internally sampled using a 16-bit analog to digital converter. The MEMS gyroscope consists of three sensors, one per axis, that produce a voltage when they are rotated.

This is the other key component in the MPU-6050 and can measure the angular momentum or rotation around the X, Y and Z axis. The accelerometer in MPU-6050 is a triple-axis accelerometer which means it senses acceleration on the X, Y and Z axis. An object travelling at constant speed will have zero acceleration. This device is used to measure acceleration, the rate of change of velocity of a particular object. Unmanned Aerial Vehicles (UAV) - Drone, helicopters.Personal Digital Assistants - Smartphones, tablets.Automotive industry - To deploy airbags, Vehicle roll handling.

The MPU-6050 sensor module also consists of a temperature sensor but it's less accurate. This sensor module is also capable of accessing external magnetometers or other sensors through an auxiliary master IIC bus to provide complete 9-axis MotionFusion output. It also has an onboard Digital Motion Processor (DMP) which processes complex 6-axis MotionFusion algorithms. It contains a MEMS 3-axis accelerometer and a MEMS 3-axis gyro in a single chip. IMUs can measure acceleration, inertia and a number of other parameters to allow you to determine their spatial position and velocity. The InvenSense MPU-6050 is a low-cost, highly accurate inertial measurement unit (IMU) with six degrees of freedom (DOF).
