Superman

Superman

By: Unitree Robotics

Launched: 2026

Unitree Superman is a high-performance bipedal humanoid prototype focused on extreme locomotion rather than general-purpose service work. It was introduced as a compact, fast-moving humanoid with a reported 0.85 m leg length, a standing vertical jump of about 2 meters, and a top running speed of 12.66 m/s, emphasizing dynamic balance and leg power over payload-heavy manipulation. Its design strongly suggests a research-oriented platform for motion-control benchmarking, athletic mobility demonstrations, and advanced humanoid development. Like Unitree’s other humanoids, it likely uses a lightweight frame, high-torque electric joints, and onboard sensing for balance and navigation. The robot appears aimed at pushing locomotion limits first, with manipulation and interaction capabilities secondary to its mobility performance.

Unitree H2 Plus

Unitree H2 Plus

By: Unitree Robotics

Launched: 2026

Unitree H2 Plus is a full-size bipedal humanoid designed for industrial-grade motion, human-like interaction, and developer-oriented research. It combines a 182 cm class standing height, 31 degrees of freedom, and high-torque joints with an expressive bionic head, making it suitable for locomotion, manipulation, and demo-grade social presence. The platform emphasizes dynamic balance, OTA-evolving motion control, and AI computing up to Jetson AGX Thor class performance. With a quick-release battery and around 3 hours of runtime, it is aimed at tasks that require agile walking, upper-body dexterity, and repeatable whole-body motions in controlled environments.

Unitree H1-2

Unitree H1-2

By: Unitree Robotics

Launched: 2024

The Unitree H1-2 is a full-size humanoid robot standing 178 cm tall with human-like proportions, optimized for advanced mobility, balance, and whole-body coordination. Featuring 27 degrees of freedom powered by high-torque M107 joint motors, it achieves walking speeds up to 2 m/s and potential mobility over 5 m/s, enabling agile navigation on complex terrains, stairs, and uneven surfaces. Equipped with 360° 3D LiDAR and depth cameras for precise environmental perception, it supports autonomous walking, running, jumping, and manipulation tasks like grasping objects with 5-finger hands. Each 7-DOF arm lifts up to 7 kg, while legs provide robust stability for dynamic motions including dancing and handshakes. Designed for research and development, the H1-2 integrates Intel Core i7 computing, swappable 864 Wh batteries for 2-hour runtime, and ROS-compatible software, making it ideal for AI training, human-robot interaction, and industrial prototyping in indoor-outdoor settings.
