ERA-42

RobotEra's end-to-end VLA embodied model, released in late 2024, driving the company's dexterous hands and humanoid robots.

ERA-42 is the embodied large model from Beijing-based RobotEra, described on the company's website as an “end-to-end VLA embodied model.” RobotEra was founded in August 2023; its founder, Jianyu Chen, is an assistant professor at Tsinghua University's Institute for Interdisciplinary Information Sciences (IIIS), and Tsinghua holds a stake in the company. According to the company's own timeline, ERA-42 was released in December 2024, with the first version demonstrated on a single arm plus a five-fingered dexterous hand; it moved to dual arms in March 2025, and by July was driving the same model across all 55 degrees of freedom of the full-size humanoid robot L7. The technical work the company's website lists as groundwork includes papers on the video prediction policy VPP, UP-VLA, the online reinforcement-learning method iRe-VLA, and the controllable world model Ctrl-World. The company says it now has 100 dexterous manipulation skills deployed in logistics, manufacturing, and commercial services; the architecture and parameter count have not been fully disclosed.

ExampleIn RobotEra's warehousing solution, a robot running on ERA-42 completes the full order-outbound-picking-scanning-packing sequence, using the 12-DOF XHAND1 dexterous hand to grasp irregularly shaped medicine boxes and flip them to scan the barcode.
