About

Wei Cheah is a robotics researcher whose work focuses on enabling mobile robots to operate in the most challenging and extreme environments, from cluttered nuclear facilities to confined underwater spaces. Their major contributions center on reconfigurable and legged robots capable of navigating narrow gaps, climbing walls, and clearing debris—tasks that are impossible for conventional platforms. Cheah’s most cited paper (39 citations) critically examines the limitations of wireless power transfer for mobile robots, highlighting a key bottleneck in tetherless operation. They have also pioneered perceptual control theory for inverted pendulum robots (36 citations) and developed the MIRRAX platform (33 citations), a reconfigurable robot designed for limited-access environments. Their work on hexapod motion planning and state estimation has advanced the ability of legged robots to traverse unknown, perpendicular surfaces. With a growing portfolio that includes multi-agent underwater systems and image-based visual servoing, Cheah’s research is directly impacting real-world inspection and safety tasks, reducing human risk in hazardous settings. Their achievements demonstrate a clear commitment to pushing the boundaries of robotic autonomy in the world’s most inaccessible places.
