9 axis wireless motion sensor ZMP® IMU - Z2 & SDK

Since 2014, sold more than 1000 units, determined version of research motion sensor (IMU, acceleration sensor)! !

 Reason why IMU-Z2 is used

 

  ・軽量&コンパクト(20g & 36×52×11[㎜])

  ・フレキシブルなセンサ構成(有線&無線対応)

  ・充実した開発環境(アプリケーション、ライブラリ、サンプルプログラム)

Overview

· The IMU - Z2 is a lightweight and compact casing, making it the optimum motion sensor for simple human movements and mobile object measurements.
· A 9-axis motion sensor with 3 axis acceleration, 3 axis angular velocity, 3 axis geomagnetism is mounted and data is measured with Bluetooth (wireless) or CAN (wired).
Up to 28 connections can be made.
· An attitude estimation library with high accuracy and improved response speed by the Extended Kalman Filter (EKF) is also available.
· A rich development environment (applications, libraries, sample programs) is prepared for general products with sensor main body alone.

Features - Sensor

Small / Wireless
· It is compact and can communicate wirelessly via Bluetooth, so you can choose the installation target and position.
· Lightweight that does not affect the exercise performance of the subject
· Can also be connected with wired (CAN)

High speed and high precision
· Small size, high performance sensor device (manufactured by STMicroelectronics) based on MEMS (3-axis acceleration sensor, 3-axis angular velocity sensor, triaxial geomagnetic sensor)
· Since it is possible to know the attitude by the geomagnetic sensor, absolute angle can be measured in a static state. Furthermore, by combining it with a gyroscope, even in a dynamic state it can be measured
· By changing the dynamic range, highly accurate measurement is possible according to the research application

Features - Application - Diverse viewer

Easily measure data and calibrate the sensor easily with the included application. Also, log output is possible.
You can synchronize and output even when using multiple.

IMU-Z Viewer 2

It is a viewer software. You can acquire the IMU - Z data and display it on the graph. There is also a log function that saves measurement data to a file. In addition, since offset and gain adjustment can be added to measurement data, data according to sensor characteristics can be measured.

With the log function, save the data just by specifying the storage location and checking the type to measure. In the calibration function, offset values ​​of acceleration, gyroscope, and geomagnetism are saved in a file, and values ​​are available automatically when read next time.

IMU-Z Cube Viewer

In addition to measuring the values ​​of acceleration, gyroscope and geomagnetism, attitude estimation is performed using the Kalman filter attitude estimator. The Euler angle and IMU - Z data are displayed graphically. At the same time, it displays a cube model and can visually check what attitude angle the measurement target is now. The measured data can also be output with the log function.

IMU-Z Model Draw Application

It is an application that displays 3D links combining pyramidal parts to measure motion data such as arm, upper body, lower body, whole body. Various link configurations can be displayed by selecting a file at the time of application startup of 3D link. By attaching the IMU - Z to each part of the body, the movement of the person and the link on the screen move synchronously. The 3D link can be edited, and you can create a link model suitable for the measurement target. Also, you can play motion data measured by using the application called IMU - Z Model Draw (BVH).

Features - Software development kit (SDK)

The SDK provides various functions for easy usage of the IMU - Z from the user 's application.
The SDK is provided as a Windows .NET component and can be developed in a general-purpose environment such as Micorosft Visual Studio. It is easy to integrate with other devices such as sensors available from Windows and to link with existing software assets.

Since we have many sample programs covering all the libraries, it is possible to start programming immediately.
A posture estimation library with high precision and improved response speed by the Extended Kalman Filter (EKF) has become available.
It is also compatible with Windows 7 "Sensor & Location Platform". Since it is possible to control the device by standard API, application development using motion sensor on Windows 7 is easy.

In addition, since CAN protocols and serial protocols are also made public, values ​​can be imported directly to instruments and controllers without using SDK.
