Fourier Robotics

Fourier

Most humanoid companies came from motors; Fourier came from medicine. The Shanghai firm, founded in 2015 and known through its fftai.com identity as Fourier Intelligence and latterly Fourier Robotics, spent nearly a decade in rehabilitation robotics before its first humanoid walked, building the exoskeletons and therapy machines now working across more than 2,000 medical institutions, devices whose entire discipline is physical contact with fragile human bodies. That inheritance, force control tuned to patients, safety engineered for clinics, touch as a first class sense, is what the company carried into its GRx humanoid series, and it explains the destination the line has reached: while the industry raced for factory payloads, Fourier built the GR-3, the first humanoid it calls a Care-Bot, a machine whose 31 touch sensors, emotionally aware perception and deliberately soft, approachable form aim not at the production line but at the eldercare facility, the hospital ward and the family home.

The series ladders a coherent progression. The GR-1 of 2023, at 165 centimetres and 55 kilogrammes, made Fourier an early mover in mass produced general purpose humanoids. The GR-2 of late 2024 industrialised the platform: 175 centimetres and 63 kilogrammes with 53 degrees of freedom, seven types of self developed FSA 2.0 actuator peaking beyond 380 newton metres, 12 degree of freedom hands whose tactile arrays identify materials and shapes in real time, and a working posting at SAIC-GM's automotive facilities to prove the point. And the GR-3 turns the accumulated craft toward care: 165 centimetres, 71 kilogrammes, 55 degrees of freedom, roughly three hours of runtime, and a hybrid mind pairing fast reflexive control with large language model reasoning behind its Full Perception Multimodal Interaction System.

Background

A decade of touching people

Rehabilitation robotics is the hardest school of physical human robot interaction: machines that grip weakened limbs, guide recovering gaits and meter forces against bodies that cannot tolerate error. Fourier's years supplying that discipline to thousands of clinics built the competencies humanoid care actually requires, compliant actuation, contact rich sensing, clinical safety culture, and its GRx series reads as their systematic transfer: first a general platform, then industrial proof, then the return home to healthcare with a machine designed to be touched.

From parallel to serial, from spec to sim

The GR-2's quiet engineering decision signals the company's practicality: redesigning joints from parallel to serial structure to simplify control, ease debugging, cut manufacturing cost and, crucially, tighten the loop between AI simulation and real world behaviour, platform choices made for learning speed rather than brochure figures, carried through a toolchain spanning the company's SDK, ROS, NVIDIA Isaac Lab and MuJoCo, with VR teleoperation and lead through programming for teaching by demonstration.

The GRx Series

Fourier GR-1

The GR-1 is the founding machine: a 165 centimetre, 55 kilogramme general purpose humanoid that put Fourier among the earliest companies to move the category from laboratory to production, establishing the locomotion, actuation and platform architecture the series built upon, with configurations and current availability confirmed at quotation.

Fourier GR-2

The GR-2 is the working generation: 175 centimetres and 63 kilogrammes with 53 degrees of freedom, powered by seven distinct FSA 2.0 actuator types delivering peak torque beyond 380 newton metres, and manipulating through 12 degree of freedom dexterous hands whose six array type tactile sensors read materials and shapes as they grip. Its detachable battery doubles the GR-1's capacity for around two hours of duty, its serial joint architecture and integrated cabling shorten maintenance and speed simulation to reality transfer, its programming spans VR remote control and lead through teaching, and its deployment at SAIC-GM automotive facilities grounds the specification in shift work, the research, industrial and service platform of the range across industrial and research robotics.

Fourier GR-3: The Care-Bot

The GR-3 is the thesis machine: the series' first Care-Bot, 165 centimetres and 71 kilogrammes with 55 degrees of freedom, around 3 kilogrammes per arm with optional 12 degree of freedom hands, and roughly three hours of runtime, wrapped in a soft, deliberately approachable industrial design that swaps the category's chrome intimidation for warmth. Its Full Perception Multimodal Interaction System fuses vision, audio and 31 touch sensors into emotionally aware response, its hybrid architecture pairs fast reflexive motion with large language model reasoning for natural conversation, and its brief is written in human places: assisted living, rehabilitation centres, hospitals, education and private homes, companionship and human centred service across companion and hospital robotics, with planned APIs opening the platform to interaction research and custom applications.

Which buyers does Fourier suit?

Fourier sells along the line its history draws. Eldercare operators, hospitals and rehabilitation providers take the GR-3's approachable interaction across health care, hospital and medical robotics, a humanoid from a supplier their sector already knows. Manufacturers and integrators take the GR-2's torque, tactile manipulation and automotive pedigree across industrial robotics. Human robot interaction laboratories take the GR-3's touch rich platform and planned APIs, and embodied AI groups take the GR-2's serial architecture and Isaac Lab, MuJoCo and ROS toolchain across research robotics. Education programmes take the series' teaching potential across educational robotics, and care sector buyers weighing the humanoid market take the consideration Fourier uniquely offers, a maker whose safety instincts were trained on patients, with mission software from the robot software catalogue completing deployments.

Technology

Touch as the family competence

Fourier's signature sense runs the whole series: rehabilitation machines that meter force against limbs, GR-2 fingertips whose arrays identify material and shape mid grip, and the GR-3's 31 body sensors making physical contact a communication channel, the sensory foundation care robotics requires and factory heritage rivals lack.

Actuation bred for bodies

The FSA 2.0 actuator family, seven types spanning the series' joints to peaks beyond 380 newton metres, descends from a decade of moving human limbs safely: torque dense enough for industrial tasks, controlled finely enough for assistance, and packaged in the serial, integrated cabling architecture that keeps the fleet maintainable.

A mind in two speeds

The GR-3's hybrid control splits cognition by tempo: reflexive layers handle balance, contact and immediate response at machine speed, whilst large language model reasoning conducts conversation, comprehension and social judgement above, the architecture that lets a care robot both catch itself and chat, with the Full Perception system feeding both from vision, sound and touch together.

Simulation to bedside

The development stack, SDK, ROS, NVIDIA Isaac Lab, MuJoCo, VR teleoperation and lead through teaching, was tuned by the GR-2's serial redesign explicitly for fast simulation to reality transfer, so behaviours train in silicon, transfer to hardware and reach deployment, automotive floors today, care settings by design, on a research grade pipeline.

Frequently Asked Questions

What is Fourier?

Fourier, also known as Fourier Intelligence and Fourier Robotics, is a Shanghai robotics company founded in 2015: a rehabilitation robotics pioneer serving more than 2,000 medical institutions, and maker of the GRx humanoid series, the GR-1, the industrial GR-2 and the GR-3 Care-Bot.

What is the Fourier GR-3?

The GR-3 is the series' first Care-Bot: a 165 centimetre, 71 kilogramme humanoid with 55 degrees of freedom, 31 touch sensors and a soft, approachable design, whose Full Perception Multimodal Interaction System and hybrid reflexive plus language model control deliver emotionally aware companionship and service for eldercare, hospitals, education and homes.

What is the Fourier GR-2?

The GR-2 is the working generation: 175 centimetres and 63 kilogrammes with 53 degrees of freedom, seven FSA 2.0 actuator types peaking beyond 380 newton metres, 12 degree of freedom hands with real time tactile material recognition, a two hour detachable battery, VR and lead through programming and industrial deployment at SAIC-GM facilities.

Why does Fourier's medical background matter?

Because care robotics is rehabilitation robotics' natural heir: a decade of machines applying controlled force to fragile bodies built the compliant actuation, contact sensing and clinical safety culture that the GRx series inherits, credentials no factory descended humanoid carries into a hospital ward.

What are the benefits of Fourier robots?

Key benefits include the category's richest touch sensing from fingertip arrays to the GR-3's 31 body sensors, actuators bred on human limbs with peaks beyond 380 newton metres, a proven simulation to reality toolchain across ROS, Isaac Lab and MuJoCo, industrial validation at automotive scale and the only Care-Bot positioning grounded in genuine medical heritage.

Who is the GR-3 designed for?

For the places robotics has promised longest and delivered least: assisted living facilities, rehabilitation centres, hospitals, schools and private homes, where its approachable form, natural conversation and emotionally aware perception make it a companion and service presence rather than an industrial visitor.

Where can I buy Fourier robots and what do they cost?

Fourier robots are for sale through Robots Europa, serving the United Kingdom, the European Union and markets worldwide with delivery, customs clearance and support. Because cost varies by model and configuration, buyers should request a tailored quotation. Full purchasing details are available on this page.

Summary

Fourier is the humanoid argument made in reverse and made stronger for it: not a machine company reaching toward people, but a medical company extending a decade of touching patients into machines that stand and walk. The GR-1 opened the series, the GR-2 proved it in automotive shift work with tactile hands and 380 newton metres of purpose, and the GR-3 Care-Bot brings it home, 31 touch sensors, two speed cognition and a soft design meant for wards, care homes and living rooms. As the medical heritage house of humanoid robotics, Fourier stands where the category's hardest promise, machines among the vulnerable, meets the one maker trained for it, and this page as the European starting point for keeping that company.
