The published capability is behavioural rather than computational: C1 performs a full set of standard etiquette moves including waving hello, bowing in greeting, turning to lead the way and politely saying goodbye, moves in a human-like and elegant way through its motion control, walks smoothly and stably without faltering under peak foot traffic, and runs quietly. It also supports dance interaction and event warm-up, and its hotel scripts and holiday greetings can be customised. The company reports that deployments achieve a 78 per cent improvement in operational efficiency, a 60 per cent increase in venue traffic activation, a 75 per cent replacement rate for high-frequency labour and a reduction in repeat enquiries. No processor, model or on-board compute hardware is published.

The engineering claims published for M1 concentrate on load, joints and safety rather than software. It is described as the industry's first fifty-kilogram-class heavy-load humanoid, with a 50 kg effective dual-arm payload, robust load-bearing walking, coordinated dual-arm torque output and dynamic load posture compensation that lets it keep its balance while carrying. Its joints are integrated high-output units with load-impact buffering, efficient thermal balance management and large instantaneous torque, delivering a peak of 430 newton metres, and every joint carries dual encoders with arm end accuracy of 1 mm or better. The safety architecture is built on hardware-level redundancy, fault self-diagnosis and alarming, and millisecond emergency braking. The company also states that M1 is grounded in real industrial working conditions, exposes open secondary-development interfaces and supports customisation across industries. Joint ranges of motion are published: the waist rotates from minus 90 to plus 90 degrees, the hip from minus 45 to plus 90 in pitch and minus 35 to plus 90 in roll, the knee combines a minus 35 to plus 35 axis with a 0 to plus 110 axis, and the ankle runs from minus 55 to plus 30 in pitch and minus 25 to plus 25 in roll.

No sensor list is published for C1. The solution text states that it carries an intelligent navigation and voice-interaction system, which it uses to greet guests, answer frequent questions about check-in, breakfast, parking and nearby facilities and guide visitors to lifts, the front desk and rest areas.

No sensor list is published for M1. The documents published with it describe the joint and safety systems instead: dual encoders on every joint, hardware-level safety redundancy, fault self-diagnosis and alarming, and millisecond emergency braking.
