BEIJING, Nov. 14, 2026 /PRNewswire/ -- If the global expansion of Chinese-made robots defined the hardware boom in the first half of the embodied AI race, the second half will be won by those that can bring down the high cost of real-world trial and error and make robot training more universal and accessible. In this underlying physics engine race long dominated by Western players, a Chinese team is now bringing a potential game-changer to the field.

Recently, Chinese company Motphys was invited to attend CoRL 2026, where it showcased its fully in-house embodied intelligence simulation engine—MotrixSim 1.0. In extreme benchmark tests against leading international physics engines, MotrixSim 1.0 demonstrates extraordinary capabilities: overwhelming established open-source engines in the contact and grasping test and vastly surpassing mainstream GPU-accelerated simulation platforms in training efficiency.

In the past, simulation was primarily used for error-proof verification at the end of the design phase. But in the era of embodied AI, AI requires massive amounts of interaction experience.

"Simulation once served to validate how machines perform. Now, it is where they learn how to perform," said Zhang Heng, co-founder and CTO of Motphys. Simulation has evolved from a "post-design validation tool" into a "physical experience production system". To power this system, Motphys builds its physics engine entirely in-house, developing the core from the ground up in Rust rather than building on existing open-source engines. This equips MotrixSim 1.0 with strong memory safety and computation power, enabling it to compete with established international players at the underlying architecture level.

In a "devil-level" disturbance-rejection grasping test where a Franka arm grasps objects of different shapes, MotrixSim 1.0 is the only engine to achieve a 100% pass rate at both 2 ms and 10 ms simulation step sizes.

In terms of compute and training efficiency.
