Sunrise Instruments

Sunrise Instruments (SRI) is a technology company founded in 2007, specializing in multi-axis force/torque (F/T) sensors, strain-gauge load cells, and force-control systems. Its headquarters is in Shanghai (China), with a US office in Canton, Michigan. The founder holds a Ph.D. from Wayne State University, with prior engineering experience at Ford Motor Company and as chief engineer at Humanetics, where he developed the world's first commercial finite-element crash-dummy model and oversaw the design of more than 100 six-axis force sensors.

SRI's portfolio includes 500+ product models deployed in 2,000+ applications, with over 60,000 sensors currently in service worldwide. The flagship M37XX series consists of 6-axis force/torque sensors (measuring Fx/Fy/Fz and Mx/My/Mz) widely used in joints, wrists and feet of humanoid robots. In 2025, SRI launched the M3701F1 — a miniature 6-axis sensor with 6 mm diameter and 1 g mass.

In robotics, SRI supplies sensors to humanoid makers such as Unitree, Fourier Intelligence, XPENG Robotics, and UBTECH, and collaborates with ABB, Yaskawa, KUKA, Foxconn, and Franka Emika. In automotive, the company provides multi-axis load cells for crash and durability testing to Humanetics, GM, SAIC, Volkswagen, Toyota, and Magna. SRI co-operates the "Robot Intelligent Joint Laboratory" with KUKA (2021) and the "iTest Intelligent Test Equipment Joint Laboratory" with SAIC (2021). Quality management is ISO 9001:2015 certified; the calibration lab is ISO/IEC 17025 certified. The company holds 27 patents and draws on 30+ years of sensor-design experience from its founder.
