YEI 3-Space™ Featured in Robotics Trends

The YEI 3-Space™ product line is a family of miniature, high-precision, high-reliability, Inertial Measurement Units (IMUs) / Attitude and Heading Reference Systems (AHRS). Each YEI 3-Space Sensor uses triaxial gyroscope, accelerometer, and compass sensors in conjunction with advanced on-board filtering and processing algorithms to determine orientation relative to an absolute reference orientation in real-time. The product family offers a breadth of communication, performance, and packaging options ranging from the ultra-miniature surface-mountable TSS Embedded module to fully integrated battery-powered TSS Bluetooth, TSS Wireless 2.4GHz, and TSS Data-logging versions.

Orientation can be returned in absolute terms or relative to a designated reference orientation. The proprietary multi-reference vector mode increases accuracy and greatly reduces and compensates for sensor error. The YEI 3-Space Sensor system also utilizes a dynamic sensor confidence algorithm that ensures optimal accuracy and precision across a wide range of operating conditions. Fully filtered orientation (AHRS) outputs at rates up to 200Hz and sensor data (IMU) outputs at rates up to 1000Hz make the 3-Space sensor products excellent choices for use in real-time or bandwidth-sensitive applications.

The YEI 3-Space™ family features are accessible via a well-documented open communication protocol that provides access to all available sensor data and configuration parameters using a variety of communication interfaces. Versatile commands allow access to raw sensor data, normalized sensor data, and filtered absolute and relative orientation outputs in multiple formats including: quaternion, Euler angles (pitch/roll/yaw), rotation matrix, axis angle, two vector (forward/up). Customers can use the free YEI 3-Space Suite™ to easily visualize this data in a graphical format as well as log data for future analysis.

The current YEI 3-Space Sensor family consists of:

• The TSS Embedded, which offers the 3-Space Sensor technology in a surface mountable module package measuring 23mm x 23mm x 2mm and weighing only 1.3 grams, is the smallest and lightest high-performance IMU/AHRS available. The TSS Embedded module offers SPI, UART, and USB interfaces.
• The TSS Wireless 2.4GHz integrates a miniature, high-precision, high-reliability, AHRS/IMU with a high-performance 2.4GHz DSSS communication interface, a USB interface, and a rechargeable lithium-polymer battery solution into a single low-cost end-use-ready unit.
• The TSS Bluetooth integrates a miniature, high-precision, high-reliability, AHRS/IMU with an industry-standard Bluetooth v2.0+EDR Class 1 interface, a USB interface, and a rechargeable lithium-polymer battery solution into a single low-cost end-use-ready unit.
• The TSS Data-logging integrates a miniature, high-precision, high-reliability, AHRS/IMU with micro-SD card storage, a USB interface, and a rechargeable lithium-polymer battery solution into a single low-cost end-use-ready unit.
• The TSS USB/RS232 integrates a miniature, high-precision, high-reliability, AHRS/IMU with both USB and RS232 asynchronous serial communication interfaces.

With prices starting at USD$99.00 in single unit quantities, YEI 3-Space Sensors are affordable for a wide range of deployments including research & development efforts, single-use applications, and high-volume commercial.
