About

Janaka Wijayakulasooriya is a robotics and control systems researcher whose work bridges theoretical advances with practical assistive technologies. His most-cited paper, "Semi-globally exponential trajectory tracking for a class of spherical robots" (2017, 21 citations), addresses a fundamental challenge in nonlinear control—achieving precise, stable motion for nonholonomic spherical robots. This work has provided a rigorous framework for trajectory tracking in these unique platforms. In the realm of human-robot interaction, Wijayakulasooriya has made notable contributions to Brain-Computer Interfacing (BCI). His 2021 paper on "Single-Channel EEG SSVEP-based BCI for Robot Arm Control" (9 citations) demonstrates a low-cost, non-invasive system that uses steady-state visual evoked potentials to enable disabled individuals to control a robotic arm with minimal training. This work highlights his commitment to accessible rehabilitation technology. Additionally, his research on sensor fusion for reconnaissance robots (2015) combines odometry and inertial data with stereo vision to generate accurate depth maps, even in the presence of wheel slip. Through these diverse contributions—from control theory to applied BCI—Wijayakulasooriya has established himself as a researcher dedicated to making robotic systems both more capable and more inclusive.
