From rehabilitation robotics to general humanoids — GR-series robots bridging healthcare and industry.
Fourier Intelligence is a Shanghai-based robotics company with a unique origin story in medical rehabilitation. Founded in 2015, Fourier built its technical foundation on exoskeleton robots for stroke rehabilitation, amassing 2,000+ hospital and clinic deployments across 40+ countries — giving it unparalleled experience in safe human-robot collaboration in sensitive environments.
This healthcare DNA directly informs Fourier's humanoid GR series. The GR-1, GR-2, and GR-3 are designed with human safety, soft manipulation, and multimodal sensing at their core — capabilities that translate directly to eldercare, hospital logistics, and home assistance use cases that competitors have largely ignored.
The GR-3 Care-bot, launched in August 2025 and showcased at CES 2026, represents Fourier's boldest product yet: a humanoid robot designed specifically for elder care, capable of assisting with mobility, monitoring health vitals, providing companionship, and performing household tasks. Fourier has partnerships with 20+ universities including ETH Zurich and Carnegie Mellon for AI development.
Fourier Intelligence makes its CES debut with GR-3, a next-generation humanoid robot designed for care-giving roles in eldercare facilities and homes, featuring full-perception multimodal AI.

The GR-2 is Fourier's most capable research humanoid, designed for teams that need high degrees of freedom, dexterous hands, and an open software ecosystem. Its 53 DoF — including 12-DoF hands with tactile sensing — make it ideal for manipulation research, healthcare logistics, and industrial trials. The FSA 2.0 actuators provide precise torque feedback for delicate handling tasks.
