Summary
To date, the world’s first fully functional male sex robot remains at the prototype or limited exhibition stage. Achieving market readiness with full-body, multi–degree-of-freedom movement and advanced semantic interaction is still 3–5 years away. At the 2025 Shanghai International Adult Products Expo (APIEXPO) held April 18–20, Realing showcased its latest male robot doll prototype, which features multiple preset position modes, basic conversational ability, and thermal–tactile feedback—marking an early foray by an Asian manufacturer into this field.

I. Industry Status
1.1 Female Robots Lead the Way
In 2017, Realbotix unveiled the “Henry” female sex robot prototype, equipped with customizable mechanical structures and rudimentary AI dialogue. However, it never entered mass production and remained a lab demonstration. Robots like Harmony can display facial expressions and engage in simple conversation, but their full-body motion is not yet mature and is limited to head and upper-limb movements.

1.2 Progress in Male Robot Development
In 2018, Realbotix announced its first male sex robot, also named Henry. Standing about 1.83 m tall, it featured an interchangeable “mechanical penis” and app-controlled voice interaction. It was available for pre-order only, never mass-produced, and has not been publicly sold. Industry insiders have noted that while its realistic appearance and high-quality vibration module were impressive, its core movement mechanics and conversational AI still require significant improvement.

II. Technical Challenges
2.1 Full-Body Motion Control
Enabling seamless position changes involving the waist and hips requires compact, high-torque servo motors and redundant sensors within a soft yet durable exterior. Current mainstream solutions support only 39–44 degrees of freedom in the upper body and cannot deliver the synchronized, fluid motions needed for realistic sexual positions.

2.2 Tactile Realism and Materials
While silicone or TPE skins can mimic human touch, embedding thermal and pressure sensors often degrades material strength and lifespan. Developing new nanocomposite materials and micro-integrated sensor arrays is key to overcoming these limitations.

2.3 Semantic Interaction and Emotional Experience
Although large language models like ChatGPT offer powerful dialogue capabilities, integrating them into a sex robot requires extensive adult-oriented corpus collection and rigorous safety reviews to prevent inappropriate content or ethical issues. Real-time voice recognition and response latency control also remain critical technical hurdles.

III. Projected Development Timeline
2025–2027: Limited-run prototypes will debut, offering multiple preset position modes, basic AI dialogue, and tactile feedback. These units will primarily appear at trade shows and as high-end custom orders.

2028–2030: Cost optimization and performance upgrades will enable the first commercially viable products, featuring fuller body motion ranges and adaptive learning capabilities, launched in small batches to global markets.

Post-2030: Technology maturity and price reductions will transform male sex robots into mainstream adult entertainment and companion devices.

IV. Realing’s Male Robot Doll at 2025 APIEXPO
At the 2025 Shanghai International Adult Products Expo, which featured over 400 exhibitors and attracted more than 50,000 visitors, Realing unveiled its male robot doll prototype. According to the company’s exhibition materials, the prototype offers:

Five Preset Position Modes: Servo motors enable limited automated adjustments in the waist and hip angles.

Basic Dialogue System: A simple AI module for keyword-triggered Q&A and pre-recorded audio responses.

Thermal and Tactile Sensors: Embedded in key contact areas to deliver initial temperature and pressure feedback.

Modular Exterior Design: Detachable head and reproductive module for customization and maintenance.

Note: These specifications are drawn from Realing’s official expo brochure and on-site materials; few public media reports exist. For finalized technical details, please refer to Realing’s forthcoming product documentation.

V. Conclusion
Delivering a truly mature male sex robot demands simultaneous breakthroughs in full-body motion control, material science, and deep AI integration. Based on current R&D trajectories, the first limited commercial models should appear within 3–5 years, though widespread adoption will take longer. Realing’s prototype at the 2025 APIEXPO provides a significant early benchmark for Asian manufacturers, and continued advances in new materials, servo technology, and AI will drive this industry into its next phase.
