Tsumiki Seisaku starts a physical AI business, training quadruped robots in simulation

Tsumiki Seisaku, a Japanese company that makes XR content, has fully launched a business that combines digital twins with physical AI, linking robotics, AR and MR support for on-site work, and VR training. On November 4 it added a page about the business to its website and began taking enquiries about joint development and proofs of concept.

The company uses Kasukabe Midori no PARK, a former primary school in Kasukabe, Saitama, as its test field. It scans indoor and outdoor areas with handheld LiDAR into 3D Gaussian splats and point clouds, brings the spaces into NVIDIA Isaac Sim to simulate robots trained in Isaac Lab, and then checks the movements with its own quadruped robot on the same site.

With reinforcement learning, its quadruped robot has learned to walk on flat ground and to climb steps and stairs, the company says, with training that allows for communication delays on the real robot. Tsumiki Seisaku will show the work and a quadruped robot at NexTech Week 2026 at Makuhari Messe from November 11 to 13.
