Motion control board
Also interfacing with the main board is the motion control board shown in Figure 2 below. The Drone uses the combination of Bosch BMA150 Accelerometer and BMP180 Barometric Pressure Sensor, Invensense IMU-3000 Gyro & Motion Processor, and Microchip PIC24HJ Microcontroller for Ultrasonic Sonar Control. Controlling the drone using Parrot’s free app is certainly aided by the addition of the gyroscope and accelerometer. Flight stability provided by counter measures to the outputs of these sensors helps the drone to respond on its own to light bumps or windy conditions.
