Fourier GR-3 Fourier Intelligence · China · 2025
A 'care-bot' humanoid from a rehabilitation-robotics pioneer, designed for warm human interaction.
Fourier leveraged a decade of rehabilitation-robotics experience to build the GR series. The GR-3 emphasizes safe human contact and emotional interaction: soft-touch surfaces, expressive audio-visual feedback and full-body compliance control, targeting eldercare, guidance and companionship scenarios in hospitals and public spaces.
