About

Sagara Sumathipala is a robotics researcher focused on autonomous navigation and human-robot interaction for small-scale mobile robots. His work addresses the critical challenge of enabling compact robots to operate effectively in constrained indoor environments where traditional GPS and vision-based odometry fail. Sumathipala’s most cited paper, “Autonomous Spiral Motion by a Small-Type Robot on an Obstacle-Available Surface” (2021, 12 citations), pioneers a novel spiral coverage algorithm that allows small robots to autonomously traverse and map obstacle-laden surfaces—a key advancement for inspection and cleaning tasks in tight spaces. He also contributed to natural user interfaces through “A Study on Mobile Robot Control by Hand Gesture Detection” (2018, 11 citations), developing skin-color-based gesture recognition for intuitive robot command. His research on fuzzy logic-based navigation (“A Study on Autonomous Entering into Narrow Path Using a Mobile Robot,” 2018, 5 citations) and adaptive motion planning for track robots (2017) further demonstrates his systematic approach to overcoming indoor localization hurdles. With cumulative citations approaching 30, Sumathipala’s work provides foundational solutions for deploying small robots in real-world confined environments, bridging the gap between theoretical control and practical autonomous operation.
