About
Hyungho Chris Choi is a roboticist whose work spans autonomous navigation, novel locomotion, and mechanical design for extreme environments. He is best known for his central role in TEAM CoSTAR’s victory in Phase II of the DARPA Subterranean Challenge, detailed in his highly cited paper “NeBula” (51 citations), which integrated robust autonomy algorithms, hardware, and software to navigate GPS-denied tunnels and urban ruins. Choi also pioneered the BAXTER bi-modal aerial-terrestrial hybrid vehicle (16 citations), enabling long-endurance versatile mobility by seamlessly transitioning between flight and ground travel. On the mechanical side, he invented the DRPD (Dual Reduction Ratio Planetary Drive) actuator (5 citations), allowing compact, switchable gear ratios for articulated robots. Most recently, his RAIBO2 quadruped robot completed a full marathon on a single battery charge (3 citations), demonstrating unprecedented energy efficiency in legged locomotion. With contributions spanning field robotics, hybrid mobility, and actuator design, Choi’s work pushes the boundaries of what autonomous systems can achieve in challenging, real-world conditions.
