About

Xi Xi is a leading figure in the field of robotics, with a primary focus on the dynamics and control of spherical mobile robots—a class of highly agile, omnidirectional platforms that present unique challenges due to their nonholonomic and underactuated nature. Her seminal work, "Path tracking control of a spherical mobile robot" (2012), which has garnered 99 citations, established foundational methods for steering these complex systems along desired trajectories. Xi further advanced the field by integrating actuator dynamics into control frameworks, as demonstrated in her 2011 paper on neural network control for linear motion, which has been cited 32 times. This work tackled the difficult problem of stabilizing and tracking the linear motion of an underactuated spherical robot, deriving a complete, third-order nonlinear dynamic model. Her 2014 study on linear motion control, though newer, continues to refine these techniques by applying Euler’s equations to model the robot’s dynamics. Through her research, Xi has provided critical theoretical and practical insights that enable more precise and reliable control of spherical robots, paving the way for their use in exploration, surveillance, and other mobile applications.
