About

Hamed Navabi is a distinguished researcher in mobile robotics and advanced control systems, with a particular focus on the modeling and control of novel robotic platforms. His most-cited work, "Position Control of the Single Spherical Wheel Mobile Robot by Using the Fuzzy Sliding Mode Controller" (2017, 24 citations), addresses the challenging dynamics of Ballbots—robots that balance and maneuver on a single actuated spherical wheel. In this influential paper, Navabi applies the Lagrangian method to derive precise governing dynamic equations, then develops a robust fuzzy sliding mode controller to achieve stable position control. This contribution is significant for advancing the field of agile, omnidirectional mobile robots, which have applications in human-robot interaction and confined-space navigation. Navabi’s research bridges theoretical mechanics and practical control design, offering solutions to the inherent instability of underactuated systems. His work has been cited by peers exploring similar nonlinear control challenges, reflecting its impact on both robotics and control engineering communities.
