About
Ranjana Sahai is a pioneering robotics researcher whose work spans microrobotics, soft sensing technologies, and humanoid robot perception. Best known for her foundational contributions to millirobot and microrobot design, her highly cited 2008 paper on fiber reinforced composite microrobots (389 citations) addressed critical fabrication challenges for centimeter-scale robots, establishing new methodologies that bridged the gap between MEMS technology and precision machining. Her early work on biomimetic crawling robots, including a remarkable 3-gram hexapod platform, demonstrated her ability to integrate diverse microrobot technologies into functional autonomous systems. Sahai also made significant strides in soft robotics sensing, introducing flexible PDMS-based curvature sensors embedded with liquid metal microchannels for joint angle proprioception — work that has garnered over 200 citations and influenced the wearable and soft robotics communities. Her research into vibrotactile surface recognition enabled humanoid robots to categorize textures through artificial fingertip sensing, earning 158 citations and pushing boundaries in robot tactile perception. Across more than two decades, Sahai's interdisciplinary contributions — encompassing fabrication, sensing, and bio-inspired locomotion — have made her a distinctive voice in the field of small-scale and embodied robotics.
