Getting Started

Congratulations on your Axiamo purchase!

We hope the information below assists you as a quick guide in setting up your Axiamote devices. You may also wish to refer to the Axiamote xRun / xData User Guide for further information.   AxiamoteBox

Installing the Axiamo app on an Android device

  1. Download the Axiamo app from the Downloads page.
  2. Before installing the app, you will need to allow apps from Unknown sources. Allowing installation from unknown sources can be a potential security risk because it allows unsigned (unverified) apps to be installed. You should always be aware of this when proceeding. In the settings menu scroll down and tap on security and select Unknown sources.unknownsources
  3. Once installed you can start the application using the imagelogo_100Axiamo icon .

Installing the Axiamo software on Windows (only 64 bit supported)

  1. First download the software from the Downloads page.
  2. Unzip the file to your desired location.
  3. You will find three folders:

    • bin
    • Storage
    • resources
  4. In the bin folder, double click on: AxiaDesk.exe to start the software.

IMPORTANT: It is vital to check that the USB Win drivers have successfully been installed onto the PC. To ensure this:

  1. Close the Axiamo software and reconnect the Axiamote device using the USB cable.
  2. Then a pop up will ask for the proper driver, which you can find in the recources folder.
  3. If no pop up appears, you can also initiate the driver installation process from the Device Manager in “Control Panel”.

Installing the Axiamo software on Ubuntu

Before installing please make sure your user is member of the “plugdev” group:
“sudo usermod -a -G plugdev <YourUserName>”

Unless you need it, please uninstall the “modem-manager” software which comes with Ubuntu, since it interferes with the Axiamo USB devices :
” sudo apt-get purge modem-manager ”

  1. First download the software from the Downloads page.
  2. Unzip the file to your desired location.
  3. You will find three folders:

    • bin
    • Storage
    • resources
  4. In the bin folder, double click on: Axiamo to start the software.

 

Charging the devices for use

Please note that Axiamote devices that are not in use should be charged every 2 months, and not left charging longer than necessary

Charge all Axiamote units for 3 hours until the LED light flashes white

  1. Connect the Axiamote unit using the micro USB cable.AxiamoCharge
  2. The light on the device will flash red, yellow, green while it is charging and white once it has finished charging and is ready for use.
  3. Please check out our FAQs for more information.

Pairing new Axiamote-Sensors with your Android device

The Axiamotes need to be first paired with your Android device. Pairing typically only needs to be done once per device. Here is a typical example of how to pair two Axiamotes:

  1. Power on both Axiamotes using the pushbotton on the device.
  2. On your Android device, go to Settings -> BluetoothBT1
  3. Turn on Bluetooth and wait until you see both Axiamotes. BT2
  4. One by one click on both Axiamotes to start the pairing process. You should see now the two Axiamotes as “Paired devices”.BT3

Connect the Axiamote-Sensors with the Axiamo-App

  1. Start the Axiamo app on your Android device. In order to connect the paired sensors with the app, click on Scan and wait until both devices (2/2) are found. This step only needs to be done once per device. Now you have to restart the app.A1Troubleshooting: If not all Axiamotes are found after the “Scanning”, make sure no other Android device is using the Axiamote-Sensor. Therefore you must unpair the particular Axiamote from the other Android device and then push again the Scan button.

Start a new Sprint Measurement

  1. Add a new User, or click on DefaultA2
  2. Click on SprintA3
  3. Click on Sprint 1kHz without Raw DataA4
  4. Use the straps to attach one Axiamote at the left foot and the other Axiamote at the right foot.Attachment
  5. Click on Start recording and make a sprintA5
  6. When you come back from sprint into bluetooth range, you must reconnect manually by closing the app and click through the menu again. Back on the Record tab you can stop the recording using the Stop recording button.

To get the best precision, it is recommended to calibrate the device before every measurement. Every IMU has a small long term drift which can be largely eliminated through pre measurement calibration.

To calibrate your device, make sure it is positioned horizontally on a flat surface and it is not moved at all while calibration.

Then open the Axiamo Host Software and press the calibration button. The device will indicate the calibration with a color burst from red to green. When the animation has finished your device has compensated all offsets and is ready for the measurement.

The Axiamote is equipped with two RGB LEDs indicating the current status.

 

 

The meaning of the different LED colors is explained below:

LED indicator description
LEDs Description
Slow white blink Device is in idle mode and is ready for a measurement.
Slow red blink Device is in idle mode and has low battery. Please recharge before starting a new measurement.
Color transition from red to green Device is charging. When device is fully charged, the LEDs will start to blink white (idle mode).
3 color blinks Device button has been pressed to signal the battery level. The color in which the device blinks three times represents the battery level. Color range is from green (full) to red (empty).
Green and red blinks Device is in recording mode. Green means sampling and red means recording to flash memory.
Green and blue blinks Device is in streaming mode. Green means sampling and blue means streaming live through USB or Bluetooth.
Color burst from red to green Device is calibrating. When animation stops, the device is calibrated and ready to use. Please read the section “Calibration” for further details.

 

  1. Change to the Archive tab and click on the Upload Upload button.A6
  2. To export the data as a matlab (mat) file or csv-file you can click on the export Export button. You will find the exported data files in the Storage folder on your Android tablet or PC.

 

  1. To analyse the measured sprint parameters, go to the Archive tab A6 and click on the measurement to display the sprint data (ground contact time) of both sensors. A7
