With the continuous development of technology, enterprises are increasingly turning to robots in an effort to automate processes (that have traditionally been done by humans). Not only can robots complete more workload in less time, but their application also minimizes the losses due to human errors, eventually improving the overall production efficiency and quality.In light of this trend, this smart biped robot is designed with a lightweight body, flexible humanoid locomotion, as well as strong adaptability, which can be applied in an array of scenarios with complex environments and tasks. Even better, it can keep up with the changes in task requirements and industry trends through iteration, which means it can flexibly incorporate multiple functions or remove unwanted ones to meet diverse task needs in different industries. It also outperforms in environmental perception. This is attributed in part to its multi-source sensing system that supports recognition and positioning of humans & objects, ReID (Re-identification), VPR (Voiceprint Recognition), and grasp detection, and in part to the speech and emotion sensing system, through which it is able to fluently answer the questions posed by users. Another highlight of its functionality lies in its interactive locomotion. It can walk smoothly, run at a maximum average speed of more than 6km/h, and maintain balance on unstructured terrains. Its mechanical hands, combined with the seven-degree-of-freedom arms, ensure flexibility in gripping and lifting, as well as precise force control like piano playing.In terms of structural design, this robot consists of lightweight, yet high-strength one-piece components, and is further equipped with a multi-source sensing system (including RGB-D cameras, a microphone array, and UWB & IMU fusion positioning system) to sense the surroundings in real time and give feedback accordingly. In addition to these configurations, this robot can also work in tandem with the Cloud Brain developed by the lab affiliated to the brand, to
