About
Manojkumar Devarassu is a robotics researcher whose work focuses on modular, reconfigurable, and autonomous systems for specialized cleaning and maintenance tasks. His primary contributions center on the design and development of the **sTetro** robot—a novel, shapeshifting platform capable of navigating both flat floors and staircases, a domain largely neglected by commercial cleaning robots. By integrating a vertical conveyor mechanism for reconfiguration, Devarassu’s sTetro platform addresses critical challenges in multi-floor building maintenance, with his foundational 2018 paper on the robot’s design earning **43 citations**. He further advanced the platform’s autonomy by incorporating deep learning for navigation and proposing a novel method for 3D absolute localization using staircase geometry and onboard sensors, achieving precise positioning without external infrastructure. Beyond sTetro, Devarassu explored self-reconfigurable tiling robots inspired by polyabolo geometry, aimed at area coverage in constrained spaces. His work has accumulated over **90 citations**, demonstrating its influence on the field of service robotics. By tackling the practical yet underexplored problem of staircase cleaning, Devarassu has made a notable impact on the development of autonomous maintenance robots for complex indoor environments.
