About

Rajiv Desai is a robotics researcher whose work spans two foundational domains: autonomous planetary rovers and fine motion planning for robotic assembly. His early contributions in the late 1980s addressed the challenging problem of automated assembly under uncertainty, developing a novel framework for fine motion planning that formally represented contact formations among polyhedral objects — work that earned 38 citations and laid important theoretical groundwork for robot programming. His 1988 paper on contact formations further extended this foundation, proposing new principles for automatic robot program generation. Desai's research trajectory shifted toward field robotics in the early 1990s, where he made significant contributions to autonomous rover navigation. His most-cited work (43 citations) documents pioneering experiments with Rocky III, a small autonomous rover capable of traversing rough outdoor terrain, locating soft soil, and collecting samples — capabilities directly relevant to planetary exploration. Subsequent work on Rocky IV advanced behavior-based control architectures designed for low-cost Mars missions, demonstrating practical autonomy in complex environments. Collectively, Desai's research bridged theoretical robot planning and real-world autonomous systems, contributing meaningfully to technologies that would eventually inform NASA's Mars rover program.
