About

Dr. W. K. I. L. Wanniarachchi is a robotics researcher specializing in human-robot interaction, autonomous navigation, and low-cost assistive robotic systems for indoor environments. Their work centers on developing accessible, user-friendly service robots that can operate effectively in unstructured office and domestic settings. Dr. Wanniarachchi’s most significant contribution is the design and implementation of the OABot (Office Assistant Robot), a service robot that uses the Message Queuing Telemetry Transport (MQTT) protocol for real-time state updates and multi-user communication, as detailed in their 2022 paper (11 citations). They have also pioneered the integration of affordable, off-the-shelf components—such as iRobot, Arduino, and Kinect sensors—with open-source software like the Robot Operating System (ROS) to create voice and keyboard-operated mobile robots for educational and practical use (2017, 6 citations). Their 2018 paper (9 citations) demonstrated a vision-based office assistant robot built with inexpensive materials, while their 2019 work (6 citations) advanced autonomous navigation and control within the ROS framework. With a cumulative impact of over 30 citations across their top papers, Dr. Wanniarachchi’s research is notable for making robotic assistance more accessible, bridging the gap between advanced robotics and real-world, low-resource applications.
