About
Longlong Chang is a pioneering roboticist whose work pushes the boundaries of insect-scale robotics, focusing on the design, actuation, and control of sub-gram autonomous machines. His most celebrated contribution is the creation of an 88-milligram autonomous crawling robot, driven by a catalytic artificial muscle—a landmark achievement that demonstrated complex, untethered behavior at a scale previously thought impossible (187 citations). Chang has also made significant strides in soft robotics, developing an earthworm-inspired robot with friction-controlled bidirectional locomotion and perceptive artificial skin, showcasing how bio-inspired design can enable adaptive movement on challenging surfaces (87 and 85 citations, respectively). In aerial robotics, he introduced Bee⁺, a 95-milligram four-winged microrobot that dramatically improved controllability over its two-winged predecessors (67 citations). His work on Preisach-model-based control of shape-memory alloy actuators further addresses the critical challenge of precise positioning under time-varying stress. With a portfolio that spans crawling, burrowing, and flying microrobots, Chang’s research is defining the future of autonomous microsystems, offering transformative potential for environmental monitoring, search-and-rescue, and medical applications.
