Seiko Epson released two new high-performance six-axis IMU

1.Press Overview

Tokyo, Japan, April 3, 2018 -

Seiko Epson (Tokyo stock exchange code: 6724, Epson) has developed two new high-performance six-axis Inertial Measurement Units (IMU) 1, M-g370 and M-g365.The two models are scheduled for mass production by the end of 2018.Epson launched the first IMU in 2011.

Since then, Epson IMU has been widely used and has gained a good reputation for excellent performance and quality.The rapid growth of demand for automated precision agricultural machinery, intelligent building machinery and unmanned vehicle applications has promoted the need for high precision positioning.Epson's new IMU was developed to provide superior quality and productivity, and to achieve the FOG2 level of performance required for autonomous driving and navigation.In addition, the new IMU maintains backward compatibility with earlier M-g364 and m-g354 to facilitate performance upgrades.

The describtion for M - G370 and M - G365

The M-G370 and M-G365 Overview

• Newly developed high-performance sensors that offer higher stability and lower noise in a wide dynamic range.
• Outstanding dynamic performance (scale factor non-linearity) for high-precision measurement, from static states to high-speed motion.
• Backward compatibility with the earlier M-G364 and M-G354, sharply reducing customer development costs and evaluation time.
• Low current consumption (16 mA, compared to 18 mA for the M-G364 and M-G354)

M - G370

Epson's top-of-the-line IMU offers FOG level performance in a 1-inch package.Ideal for inertial navigation and other applications that require superior position measurement precision, such as autonomous and unmanned applications.New development of deviation in the operation of the gyro sensor 3 can significantly improve the instability (0.8 ° / hr), 4 Angle random walk 5 and noise performance.The newly developed accelerometer significantly improves the performance of 6 uG in operation (M-g364 is 50 uG), and the initial deviation is 2 mg (1 mg).

M - G365

The next generation standard IMU has new attitude Angle output function and supports many applications.The original high speed DSP6 with extended kalman filter 7 provides highly accurate real-time attitude Angle output (roll/pitch/yaw) 8 with low power consumption.It is not necessary to calculate the dynamic attitude Angle of the system at high speed, so as to reduce the system load and power consumption.

3. Application examples

Autonomous driving and unmanned control of precision agricultural and engineering machinery.

Drones, such as industrial drones, ground and undersea vehicles.

Navigation system (GNSS9, INS10, high precision locator).

The universal camera and antenna are stable.

Vibration, Angle and path measurement of industrial equipment and vehicles.

4. Glossary of relevant terms

• The inertial measurement unit (IMU) is a device that is use for sensing inertial motion.It is consised of 3 axis angular velocity sensor and 3 axis accelerometer.
• The Fiber optic gyro( FOG) is a kind of gyroscope sensor based on fiber optic based on optical fiber and the properties of light interference， which can be found in some high-performance imus.
•  The gyroscope sensor (angular velocity sensor) measures the rotation Angle (angular velocity) of the object relative to the reference axis of unit time.
•  The gyroscope bias instability is at the specified sampling time and the average time interval computing a measure of the random variation of gyro output deviation, deviation of the change is characterized by the 1 / f noise density.

8.The latest press about Epson Corporation

-TOKYO, Japan, May 22, 2018 -

In May, Seiko Epson Corporation (TSE: 6724, "Epson") will begin a global roll-out*1 of the N6 compact 6-axis (vertically articulated) industrial robot the company announced in November 2017. Epson will also release the SH250LH, a new force sensor with a hollow design.Epson's N series of compact 6-axis robots perform tasks in tight spaces more efficiently than other robots because of a uniquely engineered "folding" arm. The N6 has a longer arm (1,000 mm) and can handle higher payloads (6 kg) than Epson's previously released N2. The N6 is ideal for loading/unloading small electronic products and automotive parts into/from test equipment. It is also perfect for shelving/unshelving medical products and much more. It has a smaller installation footprint than earlier 6-axis robots and can reach a wider range of places, from the top shelf to the bottom. These features increase productivity and the efficiency with which factory space is used.
