Sunrise Instruments (SRI) - 宇立仪器

Sunrise Instruments (brand name SRI, Chinese trade name Yuli Instruments) is a force and torque sensor manufacturer that states on its own website it was founded in 2007, with its founder previously an engineer at Ford, and that it entered the robotics sensor market in 2010. The company says it established a headquarters function in Shanghai in 2021, while a North American contact address of 8534 N Canton Center Rd, Canton, Michigan, USA is also listed on its site. A separate Chinese-language site for the same brand lists additional locations in Nanning, Guangxi and Shanghai.

SRI's core product line is six-axis force and torque load cells and sensors used in robotics and automotive testing. Its online catalog lists sensor families including the C075XX series for collaborative robots, a C025XX to C060XX range aimed at humanoid robot applications, and an M43XX series for general industrial robot arms. These sensors are typically mounted at a robot's wrist or joint to provide force and torque feedback for assembly, polishing, and compliant manipulation tasks. The company also makes Auto Crash Wall load cells for automotive crash and durability testing, and an M822XX-series data acquisition system for logging sensor signals.

A second major product family is the iGrinder line of force-controlled grinding and deburring tools designed for mounting on industrial robot arms. Listed models include the iCG03 interchangeable force-controlled grinder, a heavy-duty radial floating grinding head, floating deburring tools such as the M5314N and M5933N2, and a radial floating grinding head model M5302T1. These tools use SRI's force-sensing technology so a robot arm can hold constant contact force against a workpiece during grinding, polishing, or deburring, positioned by the company as an alternative to manual surface-finishing labor on manufacturing lines.

SRI's site states it has developed more than 500 product models, documented over 2,000 application cases, and holds 27 patents. It presents itself as a specialist in force-sensing hardware for robotics and automotive testing rather than a maker of complete robots. No employee count, funding history, or certification list was found on the pages reviewed, and the exact legal registration details of the entity exhibiting at WRC 2026 (including a Suzhou-based entity referenced in third-party listings) could not be independently confirmed.
