About

Sashreek Krishnan’s research centers on the foundational challenges of robot path planning and assembly sequence generation, with a particular focus on geometric reasoning in complex, obstacle-laden environments. His work addresses the critical problem of automatically determining collision-free paths for polyhedral robots, a key enabler for automated manufacturing and manipulation. Krishnan’s major contributions include the development of the “window corner algorithm,” a method for computing both feasible and shortest collision-free paths for translating robots in polyhedral environments. This algorithm provides a systematic approach to navigating geometric constraints, offering a solution to the classic shortest path problem. His earlier work on path planning for assembly sequence planning further demonstrates his impact, tackling the intricate task of generating operation sequences that respect geometric and mechanical feasibility. While his most-cited paper, “Path planning algorithms for assembly sequence planning” (1991), has garnered 10 citations, and the “window corner algorithm” (2003) has 2, these works represent early, principled contributions to a field that has since exploded in importance. Krishnan’s research laid essential groundwork for modern robotics and automated planning, offering elegant algorithmic solutions to enduring geometric challenges.
