I'm Rusiru Anupama Rasanjana, an Electronic and Telecommunication Engineering undergraduate at the University of Moratuwa.
I work across robotics, embodied AI, computer vision, signal processing, and embedded systems, with a particular interest in connecting perception, reasoning, and control on resource-constrained robotic systems.
