Fourier

Fourier robot platforms: the GRx humanoid series, the wheeled GRW, the open-source N1 and supply enquiries

Fourier is a Chinese company founded in 2015 that develops full-stack robotic technology. Its lineup spans the GRx humanoid series, RehabHub rehabilitation solutions, the MetaMotus Galileo biomechanics analysis platform and open-source work. The company reports serving more than 2,000 institutions and hospitals across over 60 countries. The GRx series is designed under the "Made for AI" principle and built around six core values: locomotion, cognition, bionic design, commercial viability, user experience and manipulation. Robotlar.org lists five models: the third-generation GR-3 (165 cm, 71 kg, 55 degrees of freedom, 31 pressure sensors), the wheeled dual-arm GRW (16 kg with both arms, a 2 m working height, 29 degrees of freedom), the second-generation GR-2 (175 cm, FSA 2.0 actuators, 436 N·m peak torque), the open-source research platform N1 (130 cm, 23 degrees of freedom, a published hardware package) and the series' first model, the GR-1. Fourier hardware reaches Turkey through enterprise supply; we offer interested organizations a technical assessment, a realistic view of the sourcing process and the alternatives deliverable today.

GR-3

Full-Size Care and Interaction Humanoid Robot

The Fourier GR-3 is Fourier's third generation in humanoid robotics. It stands 165 cm, weighs 71 kg and offers a 5.5 km/h walking speed, three hours of runtime, a 3 kg single-arm load capacity and 55 degrees of freedom. Fourier's proprietary Multimodal Interaction System merges vision, audio and tactile feedback into a single real-time emotional processing engine. A stereo-depth OAK camera module handles facial recognition and dynamic tracking; a four-microphone array delivers omnidirectional voice activation with echo cancellation and sound source localization; 31 pressure sensors distributed across the body detect touch in real time. The surface is Alcantara, the stuffing is a foamed material and the structure uses aluminium alloy with engineering plastic. The series comes in three configurations: GR-3, GR-3C and GR-3C Ultra. Robotlar.org assesses sourcing and alternatives together with organizations that have a GR-3 requirement.

GRW

Wheeled Dual-Arm Humanoid Handling Robot

The Fourier GRW is a dual-arm humanoid handling robot on a wheeled base. It was built for high-load assistive work across rehabilitation, eldercare, warehousing and logistics, and light manufacturing. Body height adjusts between 1160 and 1650 mm and it weighs approximately 160 kg. It carries up to 16 kg with both arms, works with a 1970 mm arm span and a 2000 mm working height, and holds ±0.1 mm repeatability. There are 29 degrees of freedom excluding end-effectors: head 2, seven per arm, waist 3, foldable lower body 2 and mobile base 8. Maximum speed is 1.5 m/s, peak torque approximately 500 N·m and the communication interface is EtherCAT. Two 720 Wh batteries provide up to four hours of operation and hot-swap without shutting the robot down. Robotlar.org assesses sourcing and alternatives together with organizations that have a GRW requirement.

GR-2

Full-Size General-Purpose Humanoid Robot

The Fourier GR-2 is Fourier's second-generation humanoid robot. It stands 175 cm and weighs approximately 63 kg; the body carries 29 degrees of freedom (head 2, waist 1, legs 6+6, arms 7+7), and with the 12-DoF dexterous hand configuration the total actuator count rises to 53. Walking speed is 5 km/h and single-arm payload approximately 3 kg. FSA 2.0 dual-encoder actuators produce a maximum joint torque of up to 436 N·m, with 23-bit encoders in the legs and 24-bit in the arms. An approximately 950 Wh removable lithium-ion battery provides about two hours of operation. Six array-type tactile sensors in the fingers sense contact force and distinguish object shape and material. Robotlar.org assesses sourcing and alternatives together with organizations that have a GR-2 requirement.

N1

Open-Source Research Humanoid Robot

The Fourier N1 is Fourier's open-source humanoid robot, built for embodied AI research. The product page states 130 cm in height, 38 kg in weight, a maximum speed of 3.5 m/s, a two-hour battery and 23 degrees of freedom. It supports dynamic movements including fast walking, running and stair climbing, aiming to let research teams validate algorithms quickly on a real body. It handles 15 to 20 degree slopes, climbs 20 cm stairs and performs moves such as single-leg balancing and ground push-ups. The frame is lightweight aluminium alloy with engineering plastic. A complete hardware resource package is published: design schematics, a bill of materials, assembly manuals and basic operating software code. Robotlar.org assesses sourcing and alternatives together with organizations that have an N1 requirement.

GR-1

First-Generation Research Humanoid Robot

The Fourier GR-1 is the first humanoid robot Fourier developed. It stands 165 cm and weighs approximately 55 kg; the body carries 32 degrees of freedom (legs 6+6, waist 3, head 3, arms 7+7), and in the dexterous-hand configuration the total actuator count reaches 44. Walking speed is 5 km/h, single-hand payload 3 kg and peak joint torque 230 N·m. The drive is based on the Fourier Smart Actuator family, which combines motor, driver, reducer and encoder into a single module. It carries a 460 Wh battery and a 20-thread Intel i7-13700H processor. Perception includes a RealSense depth camera; the pure-vision solution uses six RGB cameras with a bird's-eye-view, Transformer and occupancy network approach. Because Fourier has shifted product focus to the GR-3 and GRW, the GR-1 product page has been removed from the manufacturer's site.

FAQ

Common questions about Fourier

Can Fourier robots be bought in Turkey?

We cover Fourier requirements in Turkey through enterprise supply and integration. Share your requirement and we will plan the sourcing process together with a realistic timeline.

Which model suits which job?

The GR-3 is a care and interaction body that relates to people through touch and speech: 165 cm, 71 kg, 55 degrees of freedom, 31 pressure sensors across the body and a four-microphone array, with a 3 kg single-arm capacity. The GRW is the body that carries physical load: a wheeled base, 16 kg with both arms, an adjustable height of 1160-1650 mm, a 2 m working height and four hours of runtime. The GR-2 offers 436 N·m peak torque and a 12-DoF dexterous hand for manipulation research. The N1 is an open-source research platform: 130 cm, 23 degrees of freedom and a published hardware package that opens it to part swaps and rebuilds. The GR-1 is the first generation of the series and has been removed from the manufacturer's site.

Does Fourier also make rehabilitation products?

Yes. Alongside humanoid robots, Fourier's lineup covers RehabHub rehabilitation solutions and the MetaMotus Galileo biomechanics analysis and training platform. The Galileo is a research and training system combining virtual reality with robotics, used for movement-pattern analysis and functional performance evaluation.

Select the right Fourier model for your operation.

Choosing by brand name alone is not enough. Payload, operating environment, shift pattern, bidirectional traffic, and integration requirements should all shape the decision. We can map the right architecture with you.
