MTx


The MTx is an excellent measurement unit for orientation measurement of human body segments. The standard version MTx has a full scale acceleration of 5g, full scales of 18g are available as well.

The MTx uses 3 rate gyroscopes to track rapidly changing orientations in 3D and it measures the directions of gravity and magnetic north to provide a stable reference. The systems real-time algorithm fuses all sensor information to calculate accurate 3D orientation, with a highly dynamic response, which remains stable over time.

MT Development Kit

First-time users should acquire the MTx Development Kit. This kit includes an MTx measurement unit, a calibration certificate, a user manual, a RS232 (USB Cable) and our user friendly MT Software Development Kit (SDK).  The Development Kit allows users to fully explore the possibilities of the MTx, and the integration possibilities of the MT with your own system. With the Development Kit you have will have your measurement unit up and running in just a few minutes to start your first R&D.

Features

  • Accurate full 360 degrees 3D orientation output
  • Highly dynamic response combined with long-term stability (no drift)
  • 3D acceleration, 3D rate of turn and 3D earth-magnetic field data
  • All solid state miniature MEMS inertial sensors inside
  • Compact design
  • High update rate
  • Accepts synchronization pulses
  • Individually calibrated for temperature, 3D misalignment and
  • Sensor cross-sensitivity

Fields of use

  • Biomechanics
  • Rehabilitation
  • Sports science
  • Virtual reality
  • Ergonomics
  • Animation

Pre-set user scenarios are available optimizing the Extended Kalman Filter routine for different applications. Based on the chosen scenario the XKF will apply appropriate filter settings recommended for the application.

With the MTx Development Kit, the MTx can be easily integrated in any system or (OEM) application.

The MTx is available as a stand-alone unit or as an Xbus version. On the Xbus, Xsens’ digital data bus, multiple MTx’s can easily be used simultaneously, enabling ambulatory and cost-effective measurement of human motion.

MTx Development Kit


First-time users are advised to start with the MT Development Kit. The Development Kit contains an MTi or MTx, USB cabling, a suitcase and the software development kit. 

Xsens MTi Development Kit

More information on the MT Software Development Kit can be found below:

MT Software Development Kit


The MT Software Development Kit gives easy access to Xsens’ products, allowing users to configure and easily integrate the MTx, MTi and MTi-G Motion Trackers in their own applications. The kit contains a specially developed and easy-to-use graphical user interface, as well as drivers for various operating systems and many other useful tools, example source code and documentation.

The MT Software Development Kit contains:

  • MT Manager
  • Development Tools
    • MT API for Windows
    • C++ classes and direct low level (binary) communication for any OS
    • Example source codes
  • Magnetic Field Mapper plug-in
  • Documentation

MT Manager

The MT Manager is Windows application for easy access to the full capabilities of Xsens’ Motion Trackers. It is the tool for getting acquainted with, confguring and analyzing the Motion Trackers. The MT Manager is also capable of recording and playback MT data.

  • Real time visualization of all MT data
  • Logging, exporting and reprocessing data
  • Changing and storing settings in the firmware

MT Development Tools


The Xsens Communication MT (CMT) API will help save time in interfacing in a reliable way with Xsens Motion Trackers in a Windows environment. Direct interfacing gives full control and maximum flexibility. The example code (C/C++, Excel (VBA) and Matlab) can be easily extended to a user-specific program.

The C++ class and direct low level (binary) communication allows for reliable interfacing with Xsens Motion Trackers in any (RT)OS environment. The C++ class and direct low level (binary) communication is open source and can be used when hard real-time performance is required. The example code for Linux and Windows can be easily extended to a user-specific program.
