Overview

The Fourier GRW is a handling robot that combines a wheeled mobile base with coordinated dual-arm manipulation. It was built for high-load assistive work across rehabilitation, eldercare, warehousing and logistics, and light manufacturing.

Mechanically: height adjusts between 1160 and 1650 mm, the footprint is 720 × 618 mm, shoulder width 585 mm and weight approximately 160 kg. Arm span is 1970 mm, maximum reach height 2100 mm, maximum working height 2000 mm and turning diameter 895 mm. There are 29 degrees of freedom excluding end-effectors: head 2, single arm 7, waist 3, foldable lower body 2, mobile base 8. Peak torque is approximately 500 N·m and the communication interface is EtherCAT.

On performance: maximum speed 1.5 m/s, maximum gradeability 10 degrees, up to 16 kg dual-arm payload and ±0.1 mm repeatability. Rated voltage is 48 V, rated power approximately 1200 W, and power-loss braking is supported.

For energy there are two 720 Wh lithium-ion batteries: up to four hours of operation, approximately two hours of charging, 5.8 kg battery weight, over 2,000 cycles at 80% depth of discharge and autonomous hot swapping.

Perception includes one RGB structured-light camera, four depth cameras, two LiDAR units, eight ultrasonic sensors and a 6-axis IMU. Compute runs on an 8-core high-performance CPU with an AMD Ryzen processor under Ubuntu 22.04; NVIDIA Jetson AGX Orin or Thor is offered as the AI platform. The frame is aerospace-grade aluminium alloy and engineering plastic.

End-effectors are interchangeable: a three-finger gripper, a paddle gripper, a two-finger gripper and a dexterous hand. The FOCUS fleet management and communication system lets the robot operate alone or as part of a coordinated multi-robot system, and drag-and-drop task programming allows workflows to be built without coding.

For organizations with a GRW requirement we assess sourcing, timing and the alternatives deliverable today transparently.

Technical Analysis of a Wheeled Base in Dual-Arm HandlingDesign decisions, comparison table and evaluation

Why Wheels Instead of Two Legs

The same manufacturer's bipedal GR-3 carries 3 kg on a single arm; the wheeled GRW carries 16 kg with both. The difference is not accidental. On a bipedal body most of the carried load comes out of the balance budget: when the centre of mass shifts, the leg joints have to produce the correcting torque. On a wheeled base that budget is freed and up to 500 N·m of peak torque can go to manipulation. An 895 mm turning diameter and a 720 × 618 mm footprint are the price of the gained capacity: the robot cannot climb stairs and maximum gradeability is 10 degrees.

29 Degrees of Freedom and the Foldable Lower Body

The breakdown is: head 2, seven per arm, waist 3, foldable lower body 2, mobile base 8. The two joints in the foldable lower body vary height between 1160 and 1650 mm. That lets a single body target both a box on the floor and a shelf at a 2000 mm working height; a fixed-height handling robot would need two separate machines for that range. The three waist axes let the torso rotate while the base stays put, giving lateral reach without a wheel manoeuvre.

Hot-Swappable Batteries and Shift Arithmetic

Two 720 Wh batteries give up to four hours of operation, and charging takes approximately two hours. Without hot-swap support a robot would run four hours and stop for two; in a three-shift facility that would raise the required robot count by fifty percent. With autonomous hot swapping the battery is refreshed without shutting the robot down and downtime falls to the swap itself. Battery life exceeds 2,000 cycles at 80% depth of discharge; at two full cycles a day that means roughly three years of battery life.

Engineering Assessment

The GRW is the body in Fourier's lineup that carries the workload. Sixteen kilograms with both arms, a 2000 mm working height and ±0.1 mm repeatability bring warehouse picking and patient transfer onto the same machine; the 3 kg arm capacity of the bipedal bodies covers none of that work. Hot-swappable batteries with four hours of runtime establish a realistic base for shift planning. The limits are equally clear: 160 kg requires adequate floor loading, a 10-degree gradeability limit rules out buildings with stairs and steep ramps, and the 895 mm turning diameter has to be measured against narrow corridors.

GRW: Frequently Asked Questions

The most common questions about the Fourier GRW.

Can the Fourier GRW be bought in Turkey?

Sourcing, delivery schedule and investment for the GRW are settled per project. If you have a corporate requirement you can talk to Robotlar.org: we assess the sourcing process, a realistic timeline and the alternatives deliverable today.

What are the Fourier GRW's specifications?

Height 1160-1650 mm, footprint 720 × 618 mm, shoulder width 585 mm, weight approximately 160 kg. Arm span 1970 mm, maximum reach height 2100 mm, maximum working height 2000 mm, turning diameter 895 mm. Twenty-nine degrees of freedom excluding end-effectors: head 2, single arm 7, waist 3, foldable lower body 2, mobile base 8. Peak torque approximately 500 N·m, EtherCAT communication, 48 V nominal, approximately 1200 W rated power. Maximum speed 1.5 m/s, maximum gradeability 10 degrees, 16 kg dual-arm payload, ±0.1 mm repeatability.

Which sensors does the GRW carry?

One RGB structured-light camera, four depth cameras, two LiDAR units, eight ultrasonic sensors and a 6-axis IMU. On the compute side there is an 8-core high-performance CPU with an AMD Ryzen processor, and NVIDIA Jetson AGX Orin or Thor as the AI platform. The operating system is Ubuntu 22.04 with USB Type-C, USB 3.0 and RJ45 I/O.

How do you choose between the GRW and the GR-3?

If the work involves physical load, choose the GRW: it carries 16 kg with both arms, adjusts between 1160 and 1650 mm in height, reaches a 2000 mm working height and runs for four hours. If the work involves interacting with people, choose the GR-3: with 31 pressure sensors, a four-microphone array, facial recognition and micro-expressions it answers touch and speech, though single-arm capacity is 3 kg. The GRW cannot climb stairs; maximum gradeability is 10 degrees.

Is there a handling robot alternative deliverable today?

Yes. For warehouse and in-facility transport, Pudu Robotics service and delivery robots and Unitree quadruped platforms can be ordered now, with 4-6 week delivery, a 1-year official warranty, on-site commissioning and engineering support across Turkey. If dual-arm humanoid manipulation is required, the Unitree G1 and H2 are the candidates. Pricing is set by quote per configuration.
