Leju Robot ROBAN 2 Humanoid Robot

A Humanoid Designed for Learning and Research

ROBAN 2 is a medium-sized humanoid robot developed by China's Leju Robotics to make advanced robotics education and research more accessible. Standing approximately 1.24 metres tall, it combines a bipedal body with articulated arms, intelligent control systems, and programming tools that allow students and developers to explore how humanoid robots move and interact with their surroundings.

One of ROBAN 2's main strengths is its flexibility. The robot is available in four configurations, ranging from an entry-level version for programming and movement demonstrations to more advanced versions equipped with depth cameras, LiDAR, additional computing power, and different robotic hands.

ROBAN 2 also supports robot learning and motion-control development, making it useful for experimenting with walking behaviours, coordinated movements, and embodied AI algorithms. Its combination of accessible programming tools and advanced research capabilities makes it particularly interesting for universities, technical colleges, and robotics laboratories.

Applications: From Classroom Learning to Advanced Robotics Research

Education is one of ROBAN 2's primary applications. In schools, colleges, and universities, students can use the robot to explore programming, robot control, artificial intelligence, and humanoid movement through practical experiments. Its graphical programming tools provide an accessible starting point, while Python and more advanced development interfaces support increasingly complex projects.

ROBAN 2 is also designed for robotics research. Researchers can investigate bipedal locomotion, reinforcement learning, robot perception, autonomous navigation, and human-robot interaction. The Advanced versions add sensing and computing capabilities that support experiments involving environmental mapping, visual perception, and more sophisticated robot behaviours.

Another interesting application is interactive demonstrations and robotics competitions. ROBAN 2 can perform programmed movements, support dance and motion-development activities, and interact through supported voice and AI systems. These capabilities make it a useful platform for demonstrating robotics technologies at educational events, research exhibitions, and public showcases.

What Makes ROBAN 2 Special

What makes ROBAN 2 stand out is its focus on combining accessible robotics education with more advanced humanoid research capabilities.

Rather than offering a single fixed hardware configuration, Leju provides four versions that support different stages of learning and development. Students can begin with basic programming and robot movement before progressing to topics such as perception, navigation, reinforcement learning, and robotic manipulation.

Another important feature is its development ecosystem. ROBAN 2 is supported by programming resources, simulation tools, and robot-control interfaces that allow developers to test algorithms and experiment with different control methods. Compatible LejuLab resources also provide opportunities to explore learning-based humanoid motion control.

Its bipedal design adds another dimension to learning. Instead of working only with a stationary robot arm or wheeled educational robot, users can investigate balancing, walking, and coordinated whole-body movement.

Overall, ROBAN 2 offers a practical platform for connecting robotics theory with hands-on experimentation, from introductory demonstrations to more advanced research in embodied intelligence.

ROBAN 2 vs Other Leju Humanoid Robots

ROBAN 2 occupies a different position within Leju Robotics' humanoid lineup compared with the company's larger KUAVO robots. While KUAVO 4Pro and KUAVO 5 are full-size humanoid platforms aimed at advanced research, manipulation, and practical applications, ROBAN 2 is a smaller robot designed primarily for education, programming, and robotics research. Its different configurations allow users to explore humanoid movement, perception, navigation, and manipulation without requiring a full-size platform. KUAVO 5-W, meanwhile, uses a wheeled base and is more closely associated with industrial mobile manipulation rather than bipedal education.

Compared with Leju's smaller AELOS robots, ROBAN 2 offers a more advanced platform for research and development. The AELOS family is mainly oriented toward introductory programming, educational activities, and robotics learning, whereas ROBAN 2 provides more sophisticated perception, computing, and manipulation options. It therefore sits between Leju's compact educational robots and its full-size humanoids, offering a balance of hands-on learning and advanced robotics experimentation.
