About

Maotao Yang is a robotics researcher whose work centers on the design, modeling, and advanced motion control of spherical robots—a class of underactuated, nonholonomic systems that pose unique challenges in stability and maneuverability. His most significant contribution is the development of the XK-I spherical robot, a two-degree-of-freedom pendulum-driven platform that achieves controlled swing around both the X and Y axes, addressing critical mechanical design limitations in earlier spherical robots. Yang has pioneered the application of active disturbance rejection control (ADRC) to spherical robots, demonstrating how parameter tuning and adaptive control schemes can substantially improve anti-interference performance and motion accuracy in real-world conditions. His 2020 and 2021 papers, with 13 and 12 citations respectively, are foundational references in the field, while his 2023 work on adaptive motion control further extends the theoretical framework. By tackling the core difficulties of strong coupling and underactuation, Yang’s research provides practical pathways for deploying spherical robots in inspection, exploration, and mobile sensing applications, marking him as a key innovator in nonholonomic robotic systems.
