About
David Rajaratnam is a leading researcher at the intersection of knowledge representation, cognitive robotics, and machine ethics. His work focuses on equipping autonomous systems—from warehouse robots to social machines—with robust reasoning capabilities. Rajaratnam’s major contributions include pioneering the integration of Answer Set Programming (ASP) into the Robot Operating System (ROS), most notably through his influential ROSoClingo package, which provides a practical bridge between high-level logical reasoning and low-level robot control. He has also advanced the use of the Situation Calculus for both belief change and ethical decision-making, proposing formal frameworks that allow autonomous machines to reason about moral dilemmas. His research on hierarchical architectures for combining symbolic and sub-symbolic representations has further shaped the field of cognitive robotics. With over 40 citations across his key works, Rajaratnam’s impact is evident in both theoretical foundations and industrial applications, such as his recent work on solving large-scale warehouse delivery problems using ASP modulo difference constraints. His 2021 paper on epistemic reasoning for machine ethics represents a significant step toward embedding ethical deliberation into real-world autonomous systems.
