Wireless IMU

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
- Magnetometer

If 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,-28.140

Timestamp [sec], sensorid, x, y, z, sensorid, x, y, z, sensorid, x, y, z

Sensor 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 it's 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, traceback

host = ''
port = 5555

s = 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()
# -------------------------------------------------------

Works perfectly! Also, it would be better if the data rates are mentioned with the slow, fast etc. Also the run in background was not working out well for me. I was running my code on matlab and it stops receiving UDP packets as soon as the phone screen shuts off (inspite of enabling run in background). But overall, great app!

Simple to use and works as expected Streaming the rotation matrix available through getRotationMatrix(...) would be nice, too.
