Frequently Asked Questions (FAQ)
Depends on the model selected. Fourier GR-3, Unitree H2, Realbotix Aria are all designed for long-term family companionship. Key factors include: battery life, maintenance costs, and AI update support. It is recommended to choose brands with local agents and after-sales maintenance systems.
Highly customizable: Realbotix Aria (changeable faces, customizable personality), AINIDOLL (full appearance customization), Promobot Robo-C2 (can replicate real human faces), Actroid (very limited custom versions)
Limited customization: Chinese reception robots, Hanson Robotics Sophia (personality adjustable)
No customization: Geminoid F, Ameca, and other research-oriented models (usually finished products)
High-fidelity robots require professional repair techniques. Key check items:
✓ Does the manufacturer have agents in your region?
✓ Spare parts availability and cost
✓ Warranty period and coverage
✓ Does technical support provide remote assistance?
Recommendation: Sign a comprehensive maintenance and warranty contract before purchase.
Models with cameras and microphones require extra caution. Privacy checklist:
✓ Data storage location (local vs. cloud)
✓ Who can access recorded audio and image data?
✓ Data encryption and secure transmission protocols
✓ Is the privacy policy transparent?
Commercial scenarios: It is recommended to post privacy notices in prominent locations.
Main factors for price differences:
• Appearance realism — Silicone + real hair > engineering plastic
• Degrees of freedom and sensors — More DoF, richer sensors, higher cost
• AI licensing — Using commercial models like GPT requires additional fees
• Manufacturing location and craftsmanship — Japanese handmade customization > Chinese mass production
• After-sales system — A robust maintenance and support system incurs costs
• Production scale — Niche products have higher unit prices, mass-produced products are cheaper
Validated applications:
• Long-term care (companionship, medication reminders, emotional support)
• Commercial reception (hotel, exhibition guidance)
• Education and research (programming platforms, AI research)
• Remote kinship (video avatar, remote companionship)
• Brand display (theme parks, mall events)
Immature applications:
× Complex household chores (requires higher autonomy and mobility)
× Outdoor services (limited environmental adaptability)
× Medical procedures (safety and regulatory restrictions)
Safety design considerations:
✓ Most models have force limits (e.g., Unitree H2's 15kg payload limit)
✓ Companion robots use soft materials and gentle movements
✓ Built-in emergency stop buttons
✓ Regular safety certification
Risk factors:
× Walking robots require safety isolation in crowded environments
× Long-term battery use requires monitoring for overheating
× Users need training for correct operation
Recommendation: Ask for safety test reports and certification levels before purchasing.
Buying is suitable for: Long-term use (1 year+), family companionship, high frequency of use
Renting is suitable for: Short-term events, testing and evaluation, limited budget, experimenting with new technologies
Rental examples: Actroid DER2 rental (USD 3,500 for 5 days), short-term rental of Chinese reception robots
Return on investment: Calculate = annual cost of use / robot price. If < 30%, consider buying; if > 50%, consider renting.
Predicted technological development directions:
• Deepened AI integration — GPT-4 level natural dialogue, emotional recognition
• Improved battery life — Expected 8–12 hours of battery life
• Reduced costs — Mid-range models expected to see a 20–50% price reduction
• Modular design — Interchangeable parts, cheaper upgrades
• Enhanced outdoor capability — Improved handling of complex terrain
Purchase recommendation: If not urgent, you can wait for new product releases in the second half of 2025.
Public subsidy programs:
• Some European and American countries offer research subsidies for long-term care robots
• The Japanese government offers tax incentives for robots in an aging society
• Some local governments in China offer subsidies for commercial robots
Financing options:
• Manufacturer installment plans (e.g., Realbotix offers financing options)
• B2B enterprise leasing programs
• Bank commercial loans (depending on collateral)
Recommendation: Contact brand sales representatives to inquire about local financing options.
Conclusion
Bionic companion robots have moved from science fiction to reality. From entry-level education at USD 5,900 to high-end collectibles at USD 250,000+, the choice depends on your budget, needs, and long-term planning.
