LUS2

LUS2 is a full-size humanoid robot developed by Lumos Robotics, a Shenzhen-based high-tech company founded in 2024, specializing in industrial-grade embodied AI robots. Standing at 160 cm tall and weighing 57 kg, LUS2 represents a breakthrough in biomimetic motion control and intelligence, designed for research, education, industrial automation, service, and entertainment applications. Its architecture features a modular, open design with 28 degrees of freedom (DOF) overall, including 6 DOF per leg, enabling human-like agility. Key highlights include the ability to spring from a prone position to fully upright in just 1 second—a world-first for full-size humanoids—demonstrating superior dynamic balance recovery and real-time motion planning powered by neural AI algorithms. The robot's core computing is driven by an NVIDIA Jetson Orin AGX processor delivering 275 TOPS of AI performance, complemented by a dedicated real-time control processor for low-latency operations (150-250 ms glass-to-action). It runs on a Linux-based OS with ROS2 compatibility, open APIs, and SDKs supporting Python and C++ development. LLM integration is facilitated through external APIs, allowing autonomous behaviors, learned adaptations, and advanced decision-making. Multimodal perception is achieved via Intel RealSense D435i RGB-D cameras (~1080p), 360° LiDAR for SLAM navigation (indoor/visual/LiDAR mapping), IMU, gyroscope, ultrasonic sensors, force/temperature sensors, and high-sensitivity finger/palm tactile sensors (0.05mm deformation accuracy at 30fps). Actuation relies on self-developed high-performance electric servo motors with harmonic/planetary gears (e.g., Lumos-60-30 joint modules: 550g, 22.8Nm rated torque, 102Nm peak, 140 RPM max @48V, dual absolute encoders, EtherCAT/CAN/UART comm). Structural materials include aluminum alloy and composites for a lightweight yet robust frame. Power is supplied by a 10 Ah (10000mAh) 54V DC battery, offering 3 hours runtime per charge (2-3h recharge), with thermal management suited for -10°C to 55°C operation. LUS2 excels in dexterous manipulation (5 fingers/hand, 10 DOF hands, 5kg payload), high-speed locomotion (max 2 m/s or 7.2 km/h walking), and safe human interaction via force-limiting, collision detection, and emergency stops. Real-world deployments include silver medal in group dance at the 2025 World Humanoid Robot Games (first full-size humanoid to compete), showcases at iREX 2025, World Robot Conference 2025, China Hi-Tech Fair, and IROS 2025. As an early production/limited release model priced around $99,000, it bridges research platforms and commercial viability, accelerating embodied AI adoption in dynamic environments like healthcare, search-and-rescue, and manufacturing.
