About

Liu Junkao is a leading figure in the field of piezoelectric robotics and precision actuation, with a primary focus on developing compact, high-resolution robots for inspection and manipulation tasks. His most notable contribution is the invention of the "Crabbot," a novel pole-climbing robot driven by piezoelectric stacks, which overcomes the longstanding limitations of conventional electromagnetic and electrostatic motors—namely, their large size and poor displacement resolution. By harnessing the unique properties of piezoelectric materials, Liu has demonstrated a robot that achieves exceptional climbing precision and a significantly expanded reachable workspace, making it ideal for critical infrastructure inspection. This work, published in 2021, has already garnered 91 citations, underscoring its immediate impact on the field. Liu’s research bridges the gap between fundamental material science and practical engineering, offering a paradigm shift for applications requiring miniaturized, high-accuracy locomotion. His achievements position him as a key innovator in advanced robotics, with his Crabbot serving as a benchmark for future pole-climbing and precision-motion systems.
