GR-2
Specifications Breakdown
Height
175cmAt 175cm, the GR-2 is roughly the height of an average adult human, which allows it to interact naturally with human-designed environments including countertops, doorways, and shelving at standard heights. This size is important for robots that need to work alongside people in factories, warehouses, or homes.
Weight
63kgWeighing 63kg, the GR-2 is a substantial machine. This weight provides stability during physical tasks and manipulation but means it requires careful consideration for floor loading and may need dedicated charging infrastructure. Industrial-weight robots typically offer higher payload capacity and more robust construction.
Battery Life
2 hoursThe GR-2 offers 2 hours of battery life per charge. Battery life is one of the most critical real-world performance metrics for any mobile robot. It determines how much work the robot can accomplish in a single session before needing to recharge. For humanoid robots, this runtime should be evaluated against the size of the area you need covered and the intensity of the tasks involved. Robots with self-charging capability can partially compensate for shorter battery life by autonomously returning to their dock.
Max Speed
5 km/hThe GR-2 can move at up to 5 km/h. Maximum speed affects how quickly the robot can traverse its operating area, respond to commands, and complete tasks. For humanoid robots, speed must be balanced against safety โ faster robots need better obstacle detection and stopping capabilities to prevent collisions and ensure safe operation around people and pets.
AI Platform
Fourier AI platformThe GR-2 runs on Fourier AI platform for its artificial intelligence capabilities. The AI platform determines how intelligently the robot behaves โ from basic reactive responses to sophisticated scene understanding, natural language processing, and adaptive learning.

Owning a Fourier Robot: What to Expect
Purchasing a robot is the start of an ongoing relationship with technology that requires setup, maintenance, and periodic attention.
Setting Up Your Robot
First-time robot setup varies significantly by category and complexity. Consumer robots like vacuums and lawn mowers typically involve downloading a companion app, connecting to Wi-Fi, and running an initial mapping or boundary setup routine. More complex robots like humanoids or quadrupeds may require professional installation, calibration, and training. Allow extra time for the first session โ the robot needs to learn your space, and you need to learn its controls. Most modern robots improve their performance over the first few uses as their maps and AI models refine based on your specific environment.
Ongoing Maintenance Requirements
Every robot requires some level of maintenance to operate at peak performance. For cleaning robots, this includes emptying dustbins, washing filters, replacing brush rolls, and cleaning sensors โ typically a few minutes per week. Lawn mowing robots need periodic blade replacements and seasonal cleaning. Legged robots may require joint lubrication and firmware updates. Check the manufacturer's recommended maintenance schedule and factor replacement part costs into your total cost of ownership. Establishing a regular maintenance routine significantly extends the robot's useful life and maintains cleaning or task performance over time.
Software Updates and Long-Term Support
Modern robots receive regular software updates that can add features, improve navigation, fix bugs, and enhance security. When evaluating any robot, consider the manufacturer's track record for software support โ how frequently do they release updates, and for how long do they support older models? Some companies provide updates for years after purchase, while others may discontinue support sooner. Cloud-dependent features are particularly important to evaluate: if the manufacturer shuts down cloud services, will your robot still function? Prefer robots with strong local processing capability for long-term reliability.
Safety Considerations
Robot safety encompasses both physical safety (preventing collisions, falls, and injuries) and digital safety (data privacy, network security, camera access). Physically, look for robots with emergency stop mechanisms, collision detection, cliff sensors, and speed-limiting features when operating near people or pets. Digitally, understand what data the robot collects, where it is stored, who can access it, and whether the manufacturer has a clear privacy policy. For robots with cameras and microphones, hardware privacy indicators (LED lights when recording) and physical mute switches provide important transparency and control.
Warranty and After-Sales Support
Robotics purchases represent significant investments, making warranty terms and after-sales support critical evaluation criteria. Standard warranties in the industry range from one to three years, with some manufacturers offering extended warranty options. Beyond warranty length, consider what the warranty covers โ some exclude consumable parts like brushes and filters. Also evaluate the manufacturer's service infrastructure: do they have authorized repair centers in your region? Is support available by phone, email, or chat? Response times and repair turnaround times can vary significantly between companies. User community forums and third-party repair guides can supplement official support.
Total Cost of Ownership
The sticker price of a robot is just the beginning. Total cost of ownership includes the initial purchase price, replacement parts and consumables, electricity for charging, any subscription fees for cloud or premium features, and potential repair costs. For commercial robots, add integration, training, and downtime costs. For consumer robots, factor in accessories like extra mop pads, replacement brushes, or boundary accessories. A thorough TCO analysis over the expected product lifetime โ typically three to five years for consumer robots and longer for commercial platforms โ provides a much more accurate picture of value than purchase price alone.
For model-specific ownership details, visit individual robot pages or contact Fourier directly.
Deployment Planning for Fourier Robots
Successful robot deployment depends on preparation that goes well beyond selecting the right model.
Readiness Assessment
1
Laboratory and research environment preparation
Research deployments require controlled conditions that differ from commercial settings. Verify that the lab space meets the robot's power requirements, including dedicated circuits for charging stations and any auxiliary computing hardware. Plan for motion capture or external sensor arrays if your research protocol requires ground-truth positioning data. Establish clear demarcation between the robot's active workspace and personnel areas, especially for platforms with manipulator arms or high-speed locomotion capabilities. Document the software development environment requirements, including supported operating systems, SDK dependencies, and network configurations needed for remote operation and data collection.
2
Network infrastructure and cybersecurity planning
Modern robots are networked devices that require thoughtful integration with existing IT infrastructure. Plan a dedicated network segment or VLAN for robot operations to isolate robot traffic from critical business systems. Implement certificate-based authentication where supported, and verify that firmware update mechanisms use signed packages. Establish a security review cadence for robot software components, especially for robots that process camera feeds, microphone input, or personal data. Create an incident response plan specific to robot compromise scenarios โ what happens if a robot's navigation system is tampered with, or if sensor data is intercepted? These questions are easier to answer before deployment than during an active incident.
3
Operator training and workflow integration
Even highly autonomous robots require human operators who understand normal behavior, can recognize anomalies, and know when and how to intervene. Develop a training program that covers daily operations (startup, shutdown, charging), routine maintenance (cleaning sensors, checking mechanical wear), and emergency procedures (manual override, safe power-down, physical recovery from stuck positions). Integrate robot operations into existing workflow documentation so that robot tasks and human tasks have clear handoff points. Track operator confidence levels over time and provide refresher training when procedures change or new capabilities are deployed through software updates.
4
Performance benchmarking and acceptance criteria
Define measurable success criteria before the robot arrives. For cleaning robots, this might be coverage percentage and cleaning quality scores. For commercial service robots, track task completion rates, customer interaction quality, and mean time between interventions. For research platforms, establish reproducibility metrics and data quality thresholds. Having objective benchmarks prevents the common failure mode where a robot is judged impressive in demos but disappointing in sustained operation. Create a 30-60-90 day evaluation framework with specific milestones at each stage, and define clear decision points for scaling up, adjusting configuration, or discontinuing the deployment.
5
Regulatory compliance and liability assessment
Deploying a robot in a commercial or public-facing setting triggers regulatory considerations that vary by jurisdiction. Verify compliance with local safety standards for autonomous machines, including emergency stop accessibility, speed limitations in human-occupied spaces, and noise level restrictions. Assess liability coverage โ does your existing insurance policy cover robot-caused property damage or personal injury, or do you need a specific rider? For healthcare or eldercare companion deployments, review data privacy regulations that govern the collection and storage of health-related observations. Document your compliance posture before deployment so that auditors and regulators see proactive governance rather than reactive scrambling.
6
Long-term maintenance and total cost modeling
The purchase price of a robot is typically a fraction of the total cost of ownership over its operational lifetime. Model the full cost picture including consumables (filters, brushes, wheels, batteries), scheduled maintenance (sensor calibration, actuator inspection, firmware updates), unscheduled repairs (motor replacement, sensor failure, structural damage), and operational costs (electricity, network bandwidth, operator time). Request maintenance schedules and spare-part pricing from the manufacturer before purchase. For commercial deployments, calculate the break-even point against the labor or service cost the robot replaces, factoring in realistic uptime assumptions rather than manufacturer-stated maximums. Revisit the cost model quarterly as real operating data replaces initial estimates.
Deployment planning is iterative โ capture lessons learned and refine your approach as you progress with Fourier products.
