Fourier Intelligence Visit: GRx Humanoid Robots and Smart Rehabilitation

A Fourier Intelligence visit is one of the few places in Shanghai where a delegation can watch a humanoid robot demonstrate, then walk twenty metres and see the same company's rehabilitation robots quietly working through clinical training programmes. Fourier has been building general-purpose robots since 2015 and sells into two markets that rarely share a building: humanoid robots for reception, research, education and industry, and rehabilitation robotics for hospitals and care institutions. The equipment reaches more than 2,000 institutions and hospitals across more than 40 countries and regions. What makes the visit worth a half-day is not the demonstration — it is that both halves of the company rest on the same actuator and control stack, and the programme lets you see where that stack is genuinely mature and where it is still experimental.

Key takeaways

The programme runs at Fourier's headquarters in Pudong New Area, Shanghai, at Xiupu Road. The standard format is half a day, either 09:00 to 12:00 or 13:30 to 16:30, and combines the technology showroom, the humanoid laboratory, a themed session and a closing discussion.

The company is a general-purpose robotics business rather than a pure humanoid player. It was founded in 2015, describes its mission as empowering human life through full-stack robotics, and operates two product lines — the GRx humanoid series and a rehabilitation robotics range covering more than 30 product categories, from upper- and lower-limb rehabilitation robots to balance-training systems and physical-factor therapy devices.

The headline hardware is the GRx series. GR-1 carries Fourier's own FSA actuator and covers the major degrees of freedom of the human body; GR-2 adds a 12-degree-of-freedom dexterous hand and the FSA2.0 actuator with dual encoders. The demonstrations that matter are unglamorous: a 380 newton-metre joint torque figure shown as a robot squatting, turning and picking up objects of different materials without crushing them.

The open platform is the part developers should plan around. Fourier publishes application source code and an underlying function SDK with open interfaces, and visitors can operate the second-development platform during the laboratory segment. The company frames this as removing the barrier to embodied-AI work rather than as a product; for a visiting engineering team, what matters is how much of the stack is genuinely exposed and what remains behind the interface.

The session is where the visit earns its time, and the standard themes are the evolution from GR-1 to GR-2 or the global practice of smart rehabilitation. We arrange the programme end to end, including site scheduling on the Chinese side and English interpretation on site.

Key visit details

Where the visit is held

Location — Fourier's headquarters at Xiupu Road, Pudong New Area, Shanghai. Both halves of the business are presented on the same site: the humanoid showroom and laboratory, and the rehabilitation equipment experience area. A variant of the programme adds a visit to the Zhangjiang robot valley exhibition hall, which is in the same part of Pudong.

Getting there — the site is in eastern Pudong, roughly 40 minutes by road from the central business districts, and about the same distance from Pudong International Airport. That makes it straightforward to place on either end of a Shanghai stay. We plan transport as part of the programme, including pickup from your hotel and the transfer back.

Format and duration

Duration — half a day, running either 09:00 to 12:00 or 13:30 to 16:30. Both windows follow the same shape: registration and the showroom, a laboratory segment with live demonstrations and hands-on time on the second-development platform, a themed session with the company's technical or rehabilitation team, and a closing discussion.

Format — a guided walk with live hardware, not a slide presentation. The laboratory segment includes motion demonstrations, voice interaction with the large-model-equipped GR-1, and the opportunity to operate the development platform. Session topics are chosen in advance: the humanoid route, or the rehabilitation route, or a roundtable on the responsibilities that come with human-robot coexistence.

Who the programme suits

Best suited to — robotics and embodied-AI engineering teams; hospital rehabilitation departments and care-institution operators; medical-device distributors and healthcare investors; manufacturing teams assessing where humanoids can be deployed now; and university or research laboratories working on manipulation and human-robot interaction.

Main themes — full-stack development and what vertical integration buys an actuator company; the six-dimension framework Fourier uses to evaluate a humanoid, covering motion intelligence, cognitive intelligence, dexterous work, biomimetic design, user experience and commercial application; how a rehabilitation robot becomes a standardised clinical service rather than a device; the data flows that connect rehabilitation equipment; and where the company believes humanoids are commercially usable today.

Booking, group size and site rules

Booking — around 30 days in advance is the practical lead time, and the programme is best suited to groups of 10–20 participants. The site runs one visiting group at a time, so the date is the constraint rather than the group size.

Visiting requirements — the programme runs beside active research and demonstration areas, so photography and contact with the hardware are at the host's discretion and are confirmed during planning. The laboratory is a working space rather than an exhibition, and the schedule is adjusted on the day when a development team is mid-test.

Why a Fourier Intelligence visit is worth a delegation's day

The first reason is that the company is one of the few humanoid developers with a commercial product line that predates the humanoid boom. Rehabilitation robotics has paid the bills since 2015 and has been installed in more than 2,000 institutions and hospitals across more than 40 countries and regions. That is an unusually long feedback loop for a robotics company: clinical use is demanding, conservative and slow to adopt, and surviving it produces engineering discipline that a demonstration-only humanoid programme never acquires.

The second reason is vertical integration, and it is the argument the visit makes best. Fourier builds its own actuators, and the FSA actuator line is the reason the humanoid and the rehabilitation equipment can share a technology base. A delegation that manufactures anything should spend its time on this question rather than on the robot: which components do you build, which do you buy, and at what point does the volume of your own products justify bringing an actuator in house?

The third reason is the honesty of the timeline. The company's positioning is that AI needs a physical container to act in the world, not that the container is finished. The GRx series is described by its own maker as having reached experimental deployment in reception, research, education, industrial and rehabilitation settings. A visiting team that wants to know what a humanoid can actually do this year will get a more useful answer here than at a demonstration built around a scripted routine.

Inside the Shanghai headquarters

The half-day is arranged as five segments, and a delegation that decides in advance which of them it came for will get considerably more out of the morning or afternoon.

The showroom: the development path in one room

The showroom holds the milestone exhibits and reduced-scale models from the company's founding to the present, which is the fastest way to understand the two-track strategy. The useful detail is not the chronology but the convergence: the same actuator and control work appears on both sides of the room, first in a clinical training device, later in a biped. Delegations that skip this room tend to spend the laboratory segment asking questions the showroom already answers.

The humanoid laboratory and the live demonstrations

In the laboratory, GR-2 demonstrates dynamic movement — squatting, turning, and picking up objects of different materials with the 12-degree-of-freedom hand — while GR-1 runs voice interaction on a large-model stack. Visitors can operate the second-development platform and see the SDK-level interfaces for themselves. The segment is where technical delegations should concentrate their questions: which of the demonstrated motions are scripted trajectories, which are closed-loop, how the hand handles compliance, and what the failure modes look like when an object is misjudged.

The smart rehabilitation harbour

The rehabilitation harbour shows several upper- and lower-limb rehabilitation robots and balance-training systems working as one coordinated set, with data moving between devices as a patient progresses. This is the segment that distinguishes the visit from a humanoid showcase. What is being demonstrated is not a robot but a service model: how a care institution with no rehabilitation capability builds a standardised one, and what the equipment has to report back for that to be auditable.

The Galileo motion-quantification system

The Galileo system is a human-motion quantification platform: a six-axis platform that reproduces road conditions, a split-belt treadmill that accommodates different cadences, and a motion-capture array that records movement trajectories. Visitors can put on a headset and enter a simulated domestic or office setting to experience how a patient with a neurological injury rebuilds daily function through simulated training. For a clinical or research delegation this is the most substantive twenty minutes of the day, because motion quantification is what turns rehabilitation from an experienced therapist's judgement into a measurement.

The management platform and where the robots already work

The integrated robot management platform is presented as the answer to operating a fleet rather than a single machine: continuous monitoring of battery state, position, movement speed and actuator status, with the ability to switch a unit from autonomous patrol to manual control and take over instantly. It exists because the deployed sites are unglamorous and demanding — hotel lobbies running reception and enquiry, museums using customised corpora for guided interpretation and crowd routing, and corporate showrooms handling visitor orientation across languages. Asking which of those deployments is profitable, and which is a reference installation, is a fair question and one the host can usually answer.

Two businesses inside one company

The rehabilitation range covers more than 30 product categories — upper-limb and lower-limb rehabilitation robots, motion and balance training systems, and physical-factor therapy devices — and spans neurological, orthopaedic and pain-related treatment types. For an institution starting from nothing, the proposition is a complete standardised rehabilitation service rather than a set of machines. That packaging, rather than any single device, is the commercially interesting part of this half of the company.

The two halves also fund each other in a way worth naming. Rehabilitation generates revenue from hospitals and care institutions on equipment purchase and service cycles, which is a slower but more predictable business than humanoid sales. The humanoid programme consumes capital and produces visibility. A visiting management team should ask how the second is justified against the first, and what the internal threshold would be for the humanoid line to stop being treated as a strategic investment.

The delegations this programme is usually built for reflect both sides: hospital rehabilitation departments and care providers, robotics research groups, medical-device distributors, and technology companies looking at where embodied systems can be put to work now. Groups drawn from only one of those worlds tend to finish the half-day with an unbalanced picture, which is the argument for mixing the delegation if you have the choice.

What different teams take away

For robotics and embodied-AI engineering teams — the actuator design and the dual-encoder approach in the FSA2.0 line, the dexterous-hand mechanics, the scope of the published SDK, and a candid view of which manipulation tasks remain unsolved.

For hospital rehabilitation departments and care operators — how a standardised rehabilitation service is assembled from equipment, data and training, what the equipment reports, and how a department measures whether patients are actually improving rather than merely being treated.

For manufacturing and operations teams — where a humanoid is deployable today, which is a narrower set of tasks than the demonstrations suggest, and what the management platform implies about the real cost of running robots as a fleet rather than as machines.

For medical-device distributors and healthcare investors — the route a Chinese rehabilitation-hardware company takes into more than 40 countries, how clinical acceptance differs from technology acceptance, and what the installation base of more than 2,000 institutions is worth as a service channel.

For university and research laboratories — the cost and the openness of a platform that a research group can actually build on, and where the boundary sits between the published interfaces and the company's own development work. The same half-day should produce a different debrief for each of those five groups.

Sample visit programme

That is the shape of a standard half-day, and it is the order the site works to. It changes when the delegation adds the Zhangjiang robot valley exhibition hall, or when the session takes the rehabilitation route instead of the humanoid route; both are settled during planning. The afternoon window follows the same sequence with the subject areas in a different order.

There are so many of the strongest minds in the world exploring AI, and it still needs a physical container to carry it. That is how the company's founder and chief executive describes the case for embodied intelligence, and it is the most honest one-sentence summary of why a robotics company sells into hospitals before it sells into industrial settings.

Where a Fourier Intelligence visit can be arranged

Fourier's headquarters is in Shanghai, and that is where the programme described above runs. It sits inside a Shanghai tech tour as the robotics and healthcare anchor, which is a useful counterweight to a city better known in this sector for consumer platforms and content commerce.

Most delegations pair it with one or two other stops. The humanoid-robot incubator in Caohejing is the obvious companion for a robotics group, because it shows the whole cluster rather than a single company. Because the site sits close to Pudong International Airport, it also works as the last stop before a flight or the first after landing.

Practical notes for the day

Decide the route before you book. The humanoid route and the rehabilitation route use different speakers and different parts of the site, and asking to cover both in full produces a rushed half-day. A mixed delegation is better served by choosing one route and leaving the other to the showroom.

Bring the engineers. This is a hardware visit, and the parts that repay attention — actuator design, encoder placement, compliance in the hand, the published interfaces — need someone in the room who works on those problems. A delegation composed entirely of executives will spend the laboratory segment watching a demonstration rather than reading a system.

For clinical delegations, prepare a case. Rehabilitation teams get the most from the programme when they arrive with a specific patient cohort or service gap and ask the host how the equipment, the data and the training would be configured for it. The Galileo system in particular rewards a prepared question about what is being measured and against what baseline.

Plan for a working site, and plan for interpretation. Demonstrations can be interrupted when a development team is mid-test, so build some slack into the window. The vocabulary of actuators, degrees of freedom and rehabilitation outcome measures does not translate cleanly, so professional English interpretation is part of how we run the programme rather than an optional extra.

What previous delegations asked us to change

Three adjustments come up repeatedly when we review a programme with the groups that have just finished it, and all three are easier to decide before the booking than after.

More hands-on time, less watching. Groups consistently ask for longer on the second-development platform and in the rehabilitation harbour, and less time watching a demonstration from a distance. Where the host's schedule allows, we now extend the interactive segments and shorten the presentation.

A narrower session theme. Broad requests for an overview of humanoid robotics produce a broad answer. Groups that specify one theme — dexterous manipulation, clinical outcome measurement, or the economics of running a robot fleet — get a materially better session, and it has to be requested in advance because it determines the speaker.

Fewer stops, more depth. Delegations that try to combine this half-day with two other Shanghai visits in the same day report that the value drops. The site is in eastern Pudong, and the transfer time comes out of the programme rather than out of the day.

Questions before a Fourier Intelligence visit

Where is the visit held? At Fourier's headquarters at Xiupu Road in Pudong New Area, Shanghai. Both the humanoid showroom and laboratory and the rehabilitation experience area are on the same site.

Can we see a production line? No. This is a headquarters and development site, not a manufacturing plant. What is accessible is the showroom, the humanoid laboratory, the demonstration hardware and the rehabilitation equipment area.

Can we interact with the robots? Yes, within the laboratory segment. GR-2 runs motion and handling demonstrations, GR-1 supports voice interaction, and visitors can operate the second-development platform. Contact with the hardware is at the host's discretion on the day.

Is the SDK genuinely open? The company publishes application source code and an underlying function SDK with open interfaces, and visitors can see the interfaces during the laboratory segment. How much of the stack is exposed beyond those interfaces is a fair question to put to the host directly.

Is this visit for robotics companies or for healthcare organisations? Both, and that is unusual. The rehabilitation route is built for hospitals, care operators and distributors; the humanoid route is built for engineering and research teams. Choosing one in advance produces a better half-day than attempting both.

Can the session topic be tailored to our team? Yes. Sessions are usually built around the GR-1 to GR-2 development path, the global practice of smart rehabilitation, or a roundtable on the responsibilities that come with human-robot coexistence, and they are confirmed before the visit.

Can we add the Zhangjiang robot valley exhibition hall? Yes, as a variant of the programme. It is in the same part of Pudong, so the transfer is short, and it works best for delegations that want the cluster rather than a single company.

How far in advance should we book? Around 30 days is the practical lead time. The site runs one visiting group at a time and the speakers are drawn from active teams, so the date is the binding constraint rather than the group size.

What group size works best? The programme is best suited to groups of 10–20 participants. We charge per group, so larger groups usually offer better value per person. Individuals and smaller groups are welcome to enquire at a higher per-person rate. Larger delegations are workable and we plan the route split and the room around the number you bring.

Is English interpretation provided? Yes. English interpretation on site is part of how we run the programme, and it matters most in the rehabilitation segments, where clinical terminology carries the meaning.
