Device that will contribute to Data Acquisition module Sparkfun Razor IMU Nine Degrees of Freedom (9DoF) Incorporates three sensors into one compact board ITG-3200 Triple-Axis Gyroscope (Roll, Pitch and Yaw) ADXL345 Triple-Axis Accelerometer HMC5883L Triple-Axis Magnetometer Data is directly processed by on-board ATmega328 Output via serial communication 3.5V-16V DC input Julius Cobb

Arduino Mega will be programmed to read output from IMU via serial stream Relevant data will be output to the MPU for use by the other modules Gyroscope : Roll, Pitch and Yaw Accelerometer : X-acceleration, Y-acceleration and Z- acceleration Julius Cobb

Main purpose will be to stabilize the AUV Stabilization module will essentially poll the IMU to determine whether or not the AUV is balanced If Attitude is determined to be abnormal, run stabilization algorithms in conjunction with the Motion Control module Input IMU data Output Stabilization methods for the Motion Control module Julius Cobb

Two essential jobs Maintain stabilization of AUV Guide the AUV along the path determined by Path Planning and Decision-maker Control System modules Input Path data determined by DmCS and Path Planning modules Control data produced by the Stabilization module Output Data to increase/decrease current thrust levels for each of the six different thrusters Julius Cobb

Simultaneous control of the six thrusters via the Motion Control module will allow AUV movement in various directions Movement in basic directions is summarized by the table below : Nose of RoboSubKey Julius Cobb

Arduino Mega Operating Voltage: 5V Input Voltage: 7-12V Digital I/O Pins: 54 (15 allow PWM output) Analog Input Pins: 16 DC Current per I/O Pin: 40mA L298 H-Bridge Motor Controller Operate Voltage: 6-26V 4A total drive current Requires 5V for board power Motor direction indicator LEDs Julius Cobb
