Fourier frames GR-3 with the motto \"Love, above all functionality\": building a relationship with people first and doing tasks second.","The series has two models: GR-3, nicknamed \"Meow-bot\", for public-space interaction, elderly care and companionship for children, and GR-3C \"Cosmo\", with a harder white shell and optional LiDAR, aimed at research, higher-risk work and rehabilitation."]},{"h":"Hardware","p":["Fourier's spec sheet lists GR-3 at 1642 mm and about 71 kg, with up to 55 actuators in the 12-DoF-hand version: 2 in the head, 3 in the waist, 6 per leg, 7 per arm and 6 in the basic hand. Peak torque is 440 Nm, walking speed is at least 5.5 km/h and single-arm payload is about 3 kg.","Two hot-swappable batteries (702 Wh and 234 Wh) give about three hours on average and recharge in about 1.5 hours. The standard computer is an 8-core AMD Ryzen running Ubuntu 22.04, with NVIDIA Jetson AGX Orin or Thor as options.","Instead of a metal shell, GR-3 wears automotive upholstery (Alcantara) over foam on an aluminium and engineering-plastic frame. Thirty-one pressure sensors (16 on the head, 15 on the torso) let it respond to touch, and an LED face shows expressions."]},{"h":"Software and AI","p":["Fourier's multimodal interaction system combines stereo vision, a four-microphone array with sound-source localisation, and touch. Rule-based control handles quick reflexes while a large language model handles complex conversation. GR-3 tracks faces and turns towards whoever is speaking.","The series supports whole-body teleoperation via motion capture and custom algorithm development on a client-server architecture for researchers and integrators."]},{"h":"Use cases and deployments","p":["Fourier lists commercial services such as reception, rehabilitation and wellness, research and light industrial tasks as target uses. It has not published unit sales or named GR-3 customers."]},{"h":"Manufacturer","p":["Fourier was founded in 2015 by Alex Gu. It started with rehabilitation robots and exoskeletons and has built humanoids since 2019 (GR-1 in 2023, GR-2 in 2024, GR-3 in 2025). It is headquartered in Shanghai."]},{"h":"Price and availability","p":["Fourier does not publish a GR-3 price.
