The KUAVO 3.0 is a 45 kg humanoid from Leju Robotics of China, built as a modular, adaptable platform that can be reconfigured for many different roles. Its flexible design lets a single base serve applications that range from marketing activations to light industrial support, making it appealing to operators who want one investment to cover several use cases.
The robot walks omnidirectionally at up to 4.6 km/h and is driven by Leju's self-developed high-torque joints capable of 360 Nm peak torque at rated speeds of 150 rpm, producing strong, precise and dynamic limb movement. It runs KaihongOS built on OpenHarmony together with an open-source motion controller for trajectory planning and feedback control, and it supports integration with large AI models for higher-level reasoning, perception and interaction.
As a flexible humanoid robot, the KUAVO 3.0 fits advertising and brand activations, manufacturing support, home assistance, healthcare tasks and education, adapting its behaviour to whatever environment it is placed in. Its omnidirectional gait and modular build let it be reconfigured as requirements evolve rather than replaced.
Nexon System deploys the Leju humanoid across Southeast Asia, handling commissioning, application-specific task programming, and integration with the customer's production, facility or engagement systems. Each deployment includes operator training and ongoing maintenance and support, so the platform can be re-tasked across campaigns and departments over its life. Talk to Nexon to scope a modular-humanoid pilot.
