Story
GR-3 is Fourier's clearest attempt to move the GR line from “humanoid research platform” toward “care-oriented product.” The official page calls GR-3 a full-size care-bot and positions the GR-3C variant for more complex environments.
The public spec story is stronger than the deployment story. Fourier lists 165 cm height, 71 kg weight, 55 joints, roughly three hours of battery life, whole-body teleoperation, and hot-swappable batteries. That is enough to justify a separate successor profile instead of burying the model under GR-2.
The open question is whether GR-3 becomes a deployed service platform or remains mainly a polished product concept for research, clinical, public-service, and companion scenarios. Until customer deployments or third-party field tests appear, HumanoidRoster credits the transparent product data but keeps commercial and independent-verification scores modest.
Reality check
Fourier publishes a dedicated GR-3 Series page with dimensions, mass, joint count, battery life, teleoperation support, and application positioning. HumanoidRoster keeps the lifecycle at demo because the page is product-positioning evidence, not customer deployment or independent performance validation.
- Fourier lists GR-3 at 165 cm height, 71 kg weight, 55 joints, and about three hours of battery life
- Fourier positions GR-3 as a full-size care-bot / companion platform and GR-3C as a variant for more complex environments
- Fourier says the GR-3 Series supports whole-body teleoperation
- Fourier describes dual hot-swappable batteries and upgraded hardware with high-performance actuators and multi-DoF dexterous hands
- Care, clinical, public-service, and personal-space applications are product-positioning claims unless deployment evidence names real customers or sites
- Whole-body teleoperation is useful transparency but should not be mistaken for autonomy proof
- Product-page availability does not establish production volume or field reliability
