About

Thomas Libby is a leading researcher in bio-inspired robotics, with a primary focus on understanding how animals use their tails for dynamic stabilization, aerial reorientation, and rapid maneuvering. His work bridges biology, physics, and engineering to uncover the principles of inertial appendage control. Libby’s landmark 2012 study on tail-assisted pitch control in lizards, robots, and dinosaurs (330 citations) demonstrated that lizards can right themselves mid-air by swinging their large tails, a principle he then applied to terrestrial robots. His 2010 analytical model (127 citations) formalized how tails act as inertial appendages for body rotation, while his 2011 robotic implementation (79 citations) showed that a 177-gram robot with an active tail could achieve rapid stabilization and maneuvers. Libby’s contributions extend to comparative design frameworks (2016, 55 citations) and nonlinear control for aerial self-righting (2013, 59 citations). His recent work, including the widely discussed 2024 paper “Why animals can outrun robots” (44 citations), critically examines the performance gap between biological and robotic runners, highlighting agility, range, and robustness. Libby’s research has also produced insect-sized aerial robots with piezo-actuated tails (2019) and explored spinal twisting for reorientation (2020). His work has profoundly influenced both the understanding of animal locomotion and the design of agile, bio-inspired robots.
