Wireless IMU

Features Wireless IMU

This app sends the measurements from your phone inertial sensors via UDP as CSV (Comma-Separated Values) to a computer in your network.This turns your phone into a wireless inertial measurement unit (IMU).The following sensors are supported:- Accelerometer- Gyroscope- MagnetometerIf your phone has not all these sensors, only the available sensor data is transmitted.Example UDP packet:890.71558, 3, 0.076, 9.809, 0.565, 4, -0.559, 0.032, -0.134, 5, -21.660,-36.960,-28.140Timestamp [sec], sensorid, x, y, z, sensorid, x, y, z, sensorid, x, y, zSensor id:3 - Accelerometer (m/s^2)4 - Gyroscope (rad/s)5 - Magnetometer (micro-Tesla uT)You can run this app in the background.A warning dialog appears, if you are not connected to a WiFi network.In the example video, the stream is directly processed by a MATLAB script for Kalman Filtering.
But its up to you, what you do with the data.With the following Python script you can capture the UDP data stream from your phone:# -------------------------------------------------------import socket, tracebackhost = port = 5555s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)s.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)s.bind((host, port))while 1: try: message, address = s.recvfrom(8192) print message except (KeyboardInterrupt, SystemExit): raise except: traceback.print_exc()# -------------------------------------------------------
